WebBiofilm matrix dependence on Psl and/or Pel has been discussed in detail (Colvin et al., 2011b). Colvin et al. proposed four classes of P. aeruginosa strains based on their dependence on aggregative polysaccharides. Class I strains include those that rely predominantly on Pel for biofilm matrix stability. WebThe presence of S. salivarius K12 increased the biofilm’s biomass due to the creation of an EPS-rich matrix and the development of a complex biofilm structure . The average fluorescence intensity of the different experimental groups (for both the dead and live bacterial cells group and the EPS and live bacterial group) can be found in Figure 8 .
