Biofilms are the result of the multicellular lifestyle of B. subtilis. They are characterized by the formation of a matrix polysaccharide (poly-N-acetyl glucosamine as a major polysaccharide PubMed) and an amyloid-like protein, TasA. Correction of sfp, epsC, swrAA, and degQ as well as introduction of rapP from a plasmid present in NCIB3610 results in biofilm formation in B. subtilis 168 PubMed.
