title: Experimental biofilm and its application in malathion degradation.
abstract: Mixed bacterial culture consisting of three different strains of Micrococcus sp. (AG 36, AG 94 and AG 98) and two strains of Pseudomonas sp. (AG 7 and AG 52) and its individual components was passed through a sand column and 25.5-92% of cell dry mass was found to be retained (adsorbed) on it. Incubation of sand soaked in mineral medium containing glucose as a sole carbon source resulted in formation of a biofilm with 1.2-2.5-fold increase in biomass. A 61% degradation of malathion by the mixed culture biofilm could be achieved in 4 d.
