Bacterial biofilms are a complex community of microbes in which the cells are embedded in a polysaccharide matrix.
This slime is a mean of protection in hostile environments. Biofilms in hospital settings are perilous as they not only
make treatment difficult, cause blockage of pipes but are also cause of serious nosocomial infections thus making their
dispersal an even more important phenomenon. Any foaming method is not applicable at all places for the cleaning of
biofilms hence biofilm dispersal by household sweep containing hydrochloric acid was checked using the microliter
plate assay as dispersal strategy. Bacteria from hospital waste disposal pipes were isolated, its ability to form biofilm
was noted under different time intervals and then finally biofilm degradation was done using different concentrations
of household sweep. It was noted that household sweep can be successfully employed at many places especially waste
disposal pipes and acid resistant tubes. Our results indicated that 20% sweep (HCl conc. 1%) if used for only one
minute can reduce the biofilms to 50%. Similarly increasing contact time can reduce the biofilms further.
