Simultaneous production of cellulase and reducing sugar through modification of compositional and structural characteristic of sugarcane bagasse

Yoon LW, Ngoh GC, Chua AS

Enzyme Microb Technol, 2013 Sep 10;53(4):250-6.
PMID: 23931690 DOI: 10.1016/j.enzmictec.2013.05.005

This study examined the potential of untreated and alkali-pretreated sugarcane bagasse (SCB) in cellulase, reducing sugar (RS) and fungal biomass production via solid state fermentation (SSF) using Pycnoporus sanguineus. The impact of the composition, structure and cellulase adsorption ability of SCB on the production of cellulase, RS and fungal biomass was investigated. From the morphological and compositional analyses, untreated SCB has relatively more structural changes with a higher percentage of depolymerisation on the cellulose, hemicellulose and lignin content compared to alkali-pretreated SCB. Thus, untreated SCB favoured the production of cellulase and fungal biomass whereas alkali-pretreated SCB yielded a higher amount of RS. The composition and morphology of untreated SCB did not encourage RS production and this suggested that RS produced during SSF might be consumed in a faster rate by the more abundantly grown fungus. Besides that, alkali-pretreated SCB with higher cellulase adsorption ability could have adsorbed the cellulase produced and resulted in a lower cellulase titre. In short, the production of specific bioproducts via SSF is dependent on the structure and composition of the substrate applied.

Safety and efficacy of the COMBO bio-engineered stent in an all-comer PCI cohort: 1-Year final clinical outcomes from the MASCOT post-marketing registry

Colombo A, Chandrasekhar J, Aquino M, Ong TK, Sartori S, Baber U, et al.

Int J Cardiol, 2019 05 15;283:67-72.
PMID: 30826192 DOI: 10.1016/j.ijcard.2019.01.053

BACKGROUND: The COMBO stent (OrbusNeich Medical, Ft. Lauderdale, Florida) is a new-generation bio-engineered drug eluting stent, combining an abluminal coating of a bioabsorbable polymer matrix for sustained release of sirolimus and luminal anti-CD34 coating for endothelial progenitor cell capture and rapid endothelialization.
METHODS: The Multinational Abluminal Sirolimus Coated BiO-Engineered StenT (MASCOT) registry was a prospective post-marketing study conducted from June 2014-May 2017 across 60 centers globally. Patients were eligible if COMBO stent implantation was attempted, and they received dual antiplatelet therapy (DAPT) per local guidelines. Follow-up was conducted by trained research staff at 1, 6 and 12 months by phone or clinic visit to capture clinical events and DAPT cessation events. The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, non-fatal myocardial infarction not clearly attributable to a non-target vessel, or ischemia-driven target lesion revascularization.
RESULTS: A total of 2614 patients were enrolled over the study period with 96.7% completion of 1-year follow-up. The mean age of enrolled patients was 62.9 ± 11.2 years and 23.0% were female. Diabetes mellitus was present at baseline in 33.5%. A total of 56.1% patients underwent PCI for acute coronary syndrome (ACS). The 1-year primary endpoint of TLF occurred in 3.4% patients (n = 88). Definite stent thrombosis occurred in 0.5% patients (n = 12).
CONCLUSION: The MASCOT post marketing registry provides comprehensive safety and efficacy outcomes following contemporary PCI using the novel COMBO stent in an all-comer population. This platform is associated with low rates of 1-year TLF and ST. CLINICALTRIALS.

Pirouzi G, Abu Osman NA, Eshraghi A, Ali S, Gholizadeh H, Wan Abas WA

ScientificWorldJournal, 2014;2014:849073.
PMID: 25197716 DOI: 10.1155/2014/849073

Socket is an important part of every prosthetic limb as an interface between the residual limb and prosthetic components. Biomechanics of socket-residual limb interface, especially the pressure and force distribution, have effect on patient satisfaction and function. This paper aimed to review and evaluate studies conducted in the last decades on the design of socket, in-socket interface pressure measurement, and socket biomechanics. Literature was searched to find related keywords with transtibial amputation, socket-residual limb interface, socket measurement, socket design, modeling, computational modeling, and suspension system. In accordance with the selection criteria, 19 articles were selected for further analysis. It was revealed that pressure and stress have been studied in the last decaeds, but quantitative evaluations remain inapplicable in clinical settings. This study also illustrates prevailing systems, which may facilitate improvements in socket design for improved quality of life for individuals ambulating with transtibial prosthesis. It is hoped that the review will better facilitate the understanding and determine the clinical relevance of quantitative evaluations.

Rational Design Principles for the Transport and Subcellular Distribution of Nanomaterials into Plant Protoplasts

Lew TTS, Wong MH, Kwak SY, Sinclair R, Koman VB, Strano MS

Small, 2018 Nov;14(44):e1802086.
PMID: 30191658 DOI: 10.1002/smll.201802086

The ability to control the subcellular localization of nanoparticles within living plants offers unique advantages for targeted biomolecule delivery and enables important applications in plant bioengineering. However, the mechanism of nanoparticle transport past plant biological membranes is poorly understood. Here, a mechanistic study of nanoparticle cellular uptake into plant protoplasts is presented. An experimentally validated mathematical model of lipid exchange envelope penetration mechanism for protoplasts, which predicts that the subcellular distribution of nanoparticles in plant cells is dictated by the particle size and the magnitude of the zeta potential, is advanced. The mechanism is completely generic, describing nanoparticles ranging from quantum dots, gold and silica nanoparticles, nanoceria, and single-walled carbon nanotubes (SWNTs). In addition, the use of imaging flow cytometry to investigate the influence of protoplasts' morphological characteristics on nanoparticle uptake efficiency is demonstrated. Using DNA-wrapped SWNTs as model nanoparticles, it is found that glycerolipids, the predominant lipids in chloroplast membranes, exhibit stronger lipid-nanoparticle interaction than phospholipids, the major constituent in protoplast membrane. This work can guide the rational design of nanoparticles for targeted delivery into specific compartments within plant cells without the use of chemical or mechanical aid, potentially enabling various plant engineering applications.

Pull-out and tensile strength properties of two selected tropical trees

Normaniza Osman, Mohamad Nordin Abdullah, Che Hassandi Abdullah

Sains Malaysiana, 2011;40:1123-1127.

A bioengineering technique is gradually being used as an alternative for slope stabilisation design. The effect of vegetation on soil strength, particularly in terms of root reinforcement aspects has therefore become a major interest. However, there is a lack of documentation on the root mechanical properties available especially in Malaysia. In this study, both pull-out and tensile strength of two tropical trees namely Leucaena leucocephala and Acacia mangium were investigated on different stem sizes. L. leucocephala performs the higher pullout strength than A. mangium. The results also show that pullout resistance is much affected by the root than the shoot profiles. In terms of tensile strength, the tensile strength decreases with increasing root diameter, implying the finer root diameter contribute to the higher tensile strength. In both parameters, L. leucocephala exhibits the highest value. The study suggests that L. leucocephala has an added value as a good potential slope plant for slope stabilization work as it exhibits outstanding root mechanical properties. Interestingly, the results also showed that the pullout force was much affected by the tensile strength. It can be concluded that some root and shoot properties do have a great impact on root mechanical properties such as tensile and pullout strengths.

Production of 3-Oxo-2-(2'-pentenyl)-cyclopentane-1-octanoic Acid in the Fungus Aspergillus oryzae: A Step Towards Heterologous Production of Pyrethrins in Fungi

Mohamed ME, Pahirulzaman KA, Lazarus CM

Mol Biotechnol, 2016 Mar;58(3):172-8.
PMID: 26718544 DOI: 10.1007/s12033-015-9911-0

Pyrethrins are natural insecticides, which accumulate to high concentrations in pyrethrum (Chrysanthemum cinerariaefolium) flowers. Synthetic pyrethroids are more stable, more efficacious and cheaper, but contemporary requirements for safe and environmentally friendly pesticides encourage a return to the use of natural pyrethrins, and this would be favoured by development of an efficient route to their production by microbial fermentation. The biosynthesis of pyrethrins involves ester linkage between an acid moiety (chrysanthemoyl or pyrethroyl, synthesised via the mevalonic acid pathway from glucose), and an alcohol (pyrethrolone). Pyrethrolone is generated from 3-oxo-2-(2'-pentenyl)-cyclopentane-1-octanoic acid, which originates from α-linolenic acid via the jasmonic acid biosynthetic cascade. The first four genes in this cascade, encoding lipoxygenase 2, allene-oxide synthase, allene-oxide cyclase 2 and 12-oxophytodienoic acid reductase 3, were amplified from an Arabidopsis thaliana cDNA library, cloned in a purpose-built fungal multigene expression vector and expressed in Aspergillus oryzae. HPLC-MS analysis of the transgenic fungus homogenate gave good evidence for the presence of 3-oxo-2-(2'-pentenyl)-cyclopentane-1-octanoic acid.

Fulltext Present practices and emerging opportunities in bioengineering for slope stabilization in Malaysia: An overview

Dorairaj D, Osman N

PeerJ, 2021;9:e10477.
PMID: 33520435 DOI: 10.7717/peerj.10477

Population increase and the demand for infrastructure development such as construction of highways and road widening are intangible, leading up to mass land clearing. As flat terrains become scarce, infrastructure expansions have moved on to hilly terrains, cutting through slopes and forests. Unvegetated or bare slopes are prone to erosion due to the lack of or insufficient surface cover. The combination of exposed slope, uncontrolled slope management practices, poor slope planning and high rainfall as in Malaysia could steer towards slope failures which then results in landslides under acute situation. Moreover, due to the tropical weather, the soils undergo intense chemical weathering and leaching that elevates soil erosion and surface runoff. Mitigation measures are vital to address slope failures as they lead to economic loss and loss of lives. Since there is minimal or limited information and investigations on slope stabilization methods in Malaysia, this review deciphers into the current slope management practices such as geotextiles, brush layering, live poles, rock buttress and concrete structures. However, these methods have their drawbacks. Thus, as a way forward, we highlight the potential application of soil bioengineering methods especially on the use of whole plants. Here, we discuss the general attributions of a plant in slope stabilization including its mechanical, hydrological and hydraulic effects. Subsequently, we focus on species selection, and engineering properties of vegetation especially rooting structures and architecture. Finally, the review will dissect and assess the ecological principles for vegetation establishment with an emphasis on adopting the mix-culture approach as a slope failure mitigation measure. Nevertheless, the use of soil bioengineering is limited to low to moderate risk slopes only, while in high-risk slopes, the use of traditional engineering measure is deemed more appropriate and remain to be the solution for slope stabilization.

Moi IM, Leow ATC, Ali MSM, Rahman RNZRA, Salleh AB, Sabri S

Appl Microbiol Biotechnol, 2018 Jul;102(14):5811-5826.
PMID: 29749565 DOI: 10.1007/s00253-018-9063-9

Polyunsaturated fatty acids (PUFAs) play an important role in human diet. Despite the wide-ranging importance and benefits from heart health to brain functions, humans and mammals cannot synthesize PUFAs de novo. The primary sources of PUFA are fish and plants. Due to the increasing concerns associated with food security as well as issues of environmental contaminants in fish oil, there has been considerable interest in the production of polyunsaturated fatty acids from alternative resources which are more sustainable, safer, and economical. For instance, marine bacteria, particularly the genus of Shewanella, Photobacterium, Colwellia, Moritella, Psychromonas, Vibrio, and Alteromonas, are found to be one among the major microbial producers of polyunsaturated fatty acids. Recent developments in the area with a focus on the production of polyunsaturated fatty acids from marine bacteria as well as the metabolic engineering strategies for the improvement of PUFA production are discussed.

Phenotypic characterization of culture expanded rabbit limbal corneal keratocytes

Abd Ghafar N, Chua KH, Wan Ngah WZ, Che Hamzah J, Othman F, Abd Rahman R, et al.

Cell Tissue Bank, 2014 Mar;15(1):25-34.
PMID: 23292197 DOI: 10.1007/s10561-012-9360-y

The in vivo quiescent corneal stroma keratocytes need to be transformed to activated state in order to obtain sufficient number of cells either for monolayer evaluation or corneal stroma reconstruction. This study aimed to investigate the phenotypic characterization of corneal stromal cells during culture expansion from the limbal region of the cornea. Isolated corneal keratocytes from limbal tissue of New Zealand White Strain rabbits' corneas (n = 6) were culture expanded until three passages. Keratocytes morphology was examined daily with viability, growth rate, number of cell doubling and population doubling time were recorded at each passage. The expression of collagen type 1, aldehyde dehydrogenase (ALDH), lumican and alpha smooth muscle actin (α-SMA) were detected by RT-PCR. Immunocytochemistry was also used to detect ALDH, α-SMA, collagen type I and Cytokeratin-3 (CK3). Growth kinetic study revealed that the growth rate was low at the initial passage but increase to about two folds with concomitant reduction in population doubling time in later passages. Freshly isolated and cultured keratocytes expressed collagen type 1, ALDH and lumican but α-SMA expression was absent. However, α-SMA was expressed along with the other genes during culture expansion. Keratocytes at P1 expressed all the proteins except CK3. These results suggest that cultured keratocytes maintained most of the gene expression profile of native keratocytes while the emergence of α-SMA in serial passages showed a mix population of various phenotypes. The phenotypic characterization of monolayer keratocytes provides useful information before reconstruction of bioengineered tissue or in vitro pharmaceutical applications.

Fulltext Mesenchymal Stem Cell-Derived Extracellular Vesicles: Regenerative Potential and Challenges

Fuloria S, Subramaniyan V, Dahiya R, Dahiya S, Sudhakar K, Kumari U, et al.

Biology (Basel), 2021 Feb 25;10(3).
PMID: 33668707 DOI: 10.3390/biology10030172

Evidence suggests that stem cells exert regenerative potential via the release of extracellular vesicles. Mesenchymal stem cell extracellular vesicles (MSCEVs) offer therapeutic benefits for various pathophysiological ailments by restoring tissues. Facts suggest that MSCEV action can be potentiated by modifying the mesenchymal stem cells culturing methodology and bioengineering EVs. Limited clinical trials of MSCEVs have questioned their superiority, culturing quality, production scale-up and isolation, and administration format. Translation of preclinically successful MSCEVs into a clinical platform requires paying attention to several critical matters, such as the production technique, quantification/characterization, pharmacokinetics/targeting/transfer to the target site, and the safety profile. Keeping these issues as a priority, the present review was designed to highlight the challenges in translating preclinical MSCEV research into clinical platforms and provide evidence for the regenerative potential of MSCEVs in various conditions of the liver, kidney, heart, nervous system, bone, muscle, cartilage, and other organs/tissues.

Fulltext Functional diversity of biocatalysts: whether to bioprospect or bioengineer?

Benbelgacem, Farah Fadwa, Bellag, Oualid Abdelkader, Soroodi, Fatemeh, Abdul Aziz Ahmad, Hamzah Mohd Salleh, Noorbatcha, Ibrahim Ali

Biocatalyst should have sufficient and efficient activity for the intended
biotechnological application. In the quest for novel biocatalyst, there is a need to have a
genetic diversity either by finding it within the astronomically large number of possible
candidates or to obtain it by bioengineering an existing gene supported by various
bioinformatic and molecular engineering tools. Nowadays, it is well-known that a huge
number of microorganisms is unculturable and poses great challenges to access biocatalysts
from these microbes. Metagenomics is one of the methods widely applied to reach out
maximum possible variants to “bioprospect” biocatalysts. On the other hand, other approaches
are available to bioengineer enzymes by modifying the DNA sequence precisely based on the
structure and the function information of the protein in the case of rational design, or by a
brave creation of anarchic mutations of the DNA sequence with directed evolution method. In
this regard, both approaches, whether to bioprospect or to bioengineer biocatalysts have
advantages and disadvantages which will be discussed in this paper.KEY WORDS: Sugar

Effect of visible light on catalytic hydrolysis of p-nitrophenyl palmitate by the Pseudomonas cepacia lipase immobilized on sol-gel support

Ganasen P, Khan MR, Kalam MA, Mahmud MS

Bioprocess Biosyst Eng, 2014 Nov;37(11):2353-9.
PMID: 24879090 DOI: 10.1007/s00449-014-1213-6

This paper demonstrates Pseudomonas cepacia lipase catalyzed hydrolysis of p-nitrophenyl palmitate under irradiation of light with wavelengths of 250-750 nm. The reaction follows Michaelis-Menten Kinetics and the light irradiation increases the overall rate of hydrolysis. Using Lineweaver-Burk plot K M and V max values for the reaction in presence of light are found to be 39.07 and 66.67 mM/min/g, respectively; while for the same reaction under dark condition, the values are 7.08 and 10.21 mM/min/g. The linear form of enzyme dependent rate of reaction confirms that no mass-transfer limitations are present and the reaction is a kinetically controlled enzymatic reaction.

Fulltext Detection of dengue using PAMAM dendrimer integrated tapered optical fiber sensor

Mustapha Kamil Y, Al-Rekabi SH, Yaacob MH, Syahir A, Chee HY, Mahdi MA, et al.

Sci Rep, 2019 09 17;9(1):13483.
PMID: 31530893 DOI: 10.1038/s41598-019-49891-7

The exponential escalation of dengue cases has indeed become a global health crisis. This work elaborates on the development of a biofunctionalized tapered optical fiber (TOF) based sensor with the integration of polyamidoamine (PAMAM) dendrimer for the detection of dengue E protein. The dimension of the TOF generated an evanescent field that was sensitive to any changes in the external medium while the integration of PAMAM promoted more adhesion of bio-recognition molecules; anti-DENV II E protein antibodies; that were complementary to the targeted protein. This in return created more active sites for the absorption of DENV II E proteins onto the tapered region. The resolution and detection limit of the sensor are 19.53 nm/nM and 1 pM, respectively with Kd = 1.02 × 10-10 M.

PMID: 22299553 MyJurnal

Transplantation of cultivated limbal epithelium on substrates such as amniotic membrane is an established treatment for severe ocular surface disease with limbal stem cell deficiency. In this study, we adapted an established method to generate sheets of limbal epithelium on amniotic membrane and characterized the cells contained in these sheets and tested them for safety with regard to microbial contamination. Human limbal biopsies were cultivated on denuded amniotic membranes. After three weeks of culture, the phenotypes of cultivated cells were analyzed by immunohistochemistry and real-time RT-PCR for the expression of a panel of specific markers. Cultivated limbal epithelial cell sheets were also analyzed by scanning (SEM) and transmission (TEM) electron microscopy. Sterility tests and mycoplasma assays were conducted for the safety of product. A confluent layer of polygonal cells was formed in 2 weeks and 1-3 stratified layer of cells were observed after three weeks of culture. Cultivated cells were positive for p63, K3, K19, and involucrin but negative for K14, integrin alpha9 and ABCG2 when analyzed by immunohistochemistry. Expression of molecular markers was detectable with real-time RT-PCR. SEM showed multilayer of flat squamous polygonal epithelial cells. Desmosomal and hemidesmosomal attachments were evident. Our study showed that cultivated limbal epithelium consists of limbal progenitors as well as differentiated corneal epithelial cells. SEM and TEM analysis showed cultivated cells demonstrated typical features of corneal epithelium. The risk of contamination is low and can be prevented by culturing the cells in a clean room facility complying to Good Manufacturing Practice standard.

Biorefineries of carbon dioxide: From carbon capture and storage (CCS) to bioenergies production

Cheah WY, Ling TC, Juan JC, Lee DJ, Chang JS, Show PL

Bioresour Technol, 2016 Sep;215:346-56.
PMID: 27090405 DOI: 10.1016/j.biortech.2016.04.019

Greenhouse gas emissions have several adverse environmental effects, like pollution and climate change. Currently applied carbon capture and storage (CCS) methods are not cost effective and have not been proven safe for long term sequestration. Another attractive approach is CO2 valorization, whereby CO2 can be captured in the form of biomass via photosynthesis and is subsequently converted into various form of bioenergy. This article summarizes the current carbon sequestration and utilization technologies, while emphasizing the value of bioconversion of CO2. In particular, CO2 sequestration by terrestrial plants, microalgae and other microorganisms are discussed. Prospects and challenges for CO2 conversion are addressed. The aim of this review is to provide comprehensive knowledge and updated information on the current advances in biological CO2 sequestration and valorization, which are essential if this approach is to achieve environmental sustainability and economic feasibility.
