Both the organism has the Ability to form the Bioflim. Biofilm formation is shown to be coordinated by EPS production, cell migration, sub population differentiation and interactions. The detachment of bacteria after bioflim formation leave diefferent constituents of EPS as their “footprints,” which can be a valuable tool for tracking the trajectory of bacterial transport.

But Can you tell me, whether it is possible to get the idea about their chemical composition?and if so how...of the "footprints"?

The main extracellular polysaccaride mediating biofilm formation in staphylococci is PIA or PNAG a linear β-1,6-linked poly-N-acetylglucosamine polysaccharide. PIA is partially deacetylated and there are some hints for a possible succinylation of the polysaccharide. The best investigated EPS in Pseudomonas aeruginosa is alginate which is a linear copolymer of β-1,4-linked D-mannuronic acid and L-glucuronic acid residues.
