Fulltext Genome sequence dataset of Bacillus altitudinis strain ST14 isolated from Tunggak River in Gebeng Industrial Park, Kuantan, Pahang

Aziz AA, Zulbahri AS, Sharif MF, Mohamad MAN, Gan HM, Azizan NH

Bacillus sp. has been reported to be involved in the biodegradation of various hydrocarbon pollutants which can potentially be useful in cleaning up hydrocarbon pollutants. Here we report the draft genome of Bacillus altitudinis strain ST14 isolated from Tunggak river, Gebeng, Kuantan, an area in close proximity to industrial activities. Genome sequencing was conducted using Illumina NovaSEQ 6000 technology. Structural genes in the genome were described, including rRNAs, tRNAs, and ncRNAs. Bacillus altitudinis strain ST14 was sequenced with a length of 3,801,811 bp containing 3,891 coding sequences (CDS). Functional gene annotation reported the presence of six enzymes involved in the degradation of aromatic compounds often found in hydrocarbon pollutants.
Fulltext Pellet diameter of Ganoderma lucidum in a repeated-batch fermentation for the trio total production of biomass-exopolysaccharide-endopolysaccharide and its anti-oral cancer beta-glucan response

The pellet morphology and diameter range (DR) of Ganoderma lucidum were observed in a repeated-batch fermentation (RBF) for the trio total production of biomass, exopolysaccharide (EPS) and endopolysaccharide (ENS). Two factors were involved in RBF; broth replacement ratio (BRR: 60%, 75% and 90%) and broth replacement time point (BRTP: log, transition and stationary phase) in days. In RBF, 34.31 g/L of biomass favoured small-compact pellets with DR of 20.67 µm< d < 24.00 µm (75% BRR, day 11 of BRTP). EPS production of 4.34 g/L was prone to ovoid-starburst pellets with DR of 34.33 µm< d <35.67 µm (75% BRR, day 13 of BRTP). Meanwhile, the highest 2.43 g/L of ENS production favoured large-hollow pellets with DR of 34.00 µm< d < 38.67 µm (90% BRR, day 13 of BRTP). In addition, RBF successfully shortened the biomass-EPS-ENS fermentation period (31, 33 and 35 days) from batch to 5 days, in seven consecutive cycles of RBF. In a FTIR detection, β-glucan (BG) from EPS and ENS extracts were associated with β-glycosidic linkages (2925 cm-1, 1635 cm-1, 1077 cm-1, 920 cm-1 and 800 cm-1 wavelengths) with similar 1H NMR spectral behaviour (4.58, 3.87 and 3.81 ppm). Meanwhile, 4 mg/L of BG gave negative cytotoxic effects on normal gingival cell line (hGF) but induced antiproliferation (IC50 = 0.23 mg/mL) against cancerous oral Asian cellosaurus cell line (ORL-48). Together, this study proved that G. lucidum mycelial pellets could withstand seven cycles of long fermentation condition and possessed anti-oral cancer beta-glucan, which suits large-scale natural drug fermentation.

Obesity is a metabolic disorder that has become critically prevalent throughout the world. Obesity has been linked to other chronic diseases such as diabetes mellitus, cardiovascular diseases and cancer. Natural products such as honey have been investigated for their potential effect on obesity. Hence, this study systematically reviewed the recent literature concerning the effects of honey on obesity in obese animal models and in people with obesity. The Ovid MEDLINE, PubMed, Scopus, Web of Science and Google Scholar electronic databases were searched for relevant articles. A total of 130 relevant articles were obtained from the initial search. Following a thorough screening, nine articles were selected for data extraction, including six animal studies and three clinical trials. In most of the animal studies, honey demonstrated an anti-obesity effect by reducing body weight, body fat composition and adipocyte size, among others. However, supplementation of honey in clinical trials showed conflicting results. Even though honey supplementation did not demonstrate any weight-reducing effect in some of the clinical trials, none of the trials showed that honey increases body weight. However, the results should be interpreted with caution as most of the studies involved animal models and there is a limited number of high quality, randomized, controlled clinical trials.
