Beneficial biofilm formation by industrial bacteria Bacillus subtilis and related species

Identification and characterization of Bacillus subtilis from grass carp (Ctenopharynodon idellus) for use as probiotic additives in aquatic feed

“…Biofilm are microbial communities encased by a self-made extracellular matrix [52]. Formation of probiotic biofilm has many benefits to host intestinal health via: (1) producing specific secondary metabolites and significantly increasing the resistivity to biological, chemical and physical assaults in the gut [53], (2) increasing the colonization efficiency and local concentration of antibiotics, (3) protecting gut epithelium by competing with pathogens for adherence sites, and (4) inducing host immune reactions to the pathogens [54]. In this study, all the isolated B. subtilis strains were capable of forming biofilms at high levels.…”

Biodegradation of Pharmaceutical Wastes in Treated Sewage Effluents by Bacillus subtilis 1556WTNC

“…The considerations in the enzymatic treatment of wastewaters are the presence of substrates, which may inhibit the growth and production of enzymes by the added bacterial strains (Morikawa 2006). Therefore, in the current study, the bacteria strains were tested to study the potential to grow and produce β-lactamase in treated sewage effluents.…”

Biosurfactants and Bioemulsifiers Biomedical and Related Applications – Present Status and Future Potentials

“…Current biofilm preventive strategies are essentially aimed at coating medical surfaces with antimicrobial agents, a process not always successful (Basak et al, 2009;von Eiff et al, 2005). Bacteria in biofilms become highly resistant to antibiotics, and so they evade host defenses withstanding antimicrobial chemotherapy (Morikawa, 2006). Since nosocomial infections remain an important problem even for hospitals with strict infection control programmes, infection control measures remain highly sought after (Falagas & Makris, 2009).…”
