| Abstract: | A blocking agent of polysaccharide synthesis (5 x 10-4 M 2,4-dinitrophenol) was continuously added to a reaction system, where a heterogeneous microbial population was cultivated at a dilution rate of 0.1 h-1. The results indicate that adhesion and biofilm accumulation were severely reduced when exopolysaccharydes synthesis was blocked. |
