E. Coli (IMAGE) University of Birmingham Caption The researchers screened synthetic polymers for their ability to induce biofilm formation in a strain of E. coli (MC4100), which is known to be poor at forming biofilms. They also monitored the biomass and biocatalytic activity of both MC4100 and PHL644 (a good biofilm former), incubated the presence of these polymers, and found that MC4100 matched and even outperformed PHL644.
