Abstract |
Although numerous techniques have been standardized for assessing the metabolic activities of free-living (suspended) microorganisms, little corresponding methodology has been developed for attached microorganisms. Because attached microorganisms, such as those in biofilms, may dominate the microbiology of shallow aquatic ecosystems, methods designed specifically for measuring their activities are a much needed tool in environmental science. The following method gives detailed procedures for measuring the rates of biofilm removal of rapidly degraded hydrophilic organic substrates. Using replicate Teflon strips colonized in aquatic microcosms and a benchmark chemical (2,4-dichlorophenoxyacetic acid methyl ester), substrate removal rate coefficients were determined for a particular ratio of colonized surface area to container volume. These coefficients are applicable in mathematical models used to predict chemical removal rates under field conditions. (Copyright (c) 1989 Elsevier Science Publishers B.V.) |
