ABSTRACT
The biodegradability of pollutants introduced into aquatic environments is subject to many variabilities characteristic of microbial processes. Some observations have been reported on studies with p-cresol, methyl parathion, benzo[b]thiophene, dibenzothiophene, 9H-carbazole, quinoline, benzo[f]quinoline, benz[a]anthracene, benzo[a]pyrene, 7H-dibenzo[c,g]carbazole, Mirex, 2,4-dichlorophenoxyacetic acid, Lindane and 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane analogs. Water reservoirs included a eutrophic stream, a eutrophic pond, an oligotrophic lake and effluents from waste-water treatment plants. The first ten of the above compounds were studied only in aerobic mixed-culture systems, and Mirex was studied with mixed cultures under both aerobic and anaerobic conditions. Examples were presented of the significance of cometabolism, diauxic processes, film fermentations and microbial interactions in biodegradation studies. Caution is advised in protocols regarding biodegradability of pollutants in aquatic environments.
