Using 2,4-dichlorophenoxyacetic acid methyl ester (2,4-DME) as a benchmark chemical, we determined relative pseudo-first-order rate coefficients for the butoxyethyl ester of 2,4-dichlorophenoxyacetic acid (2,4-DBE), methyl parathion, and methyl-3-chlorobenzoate in a diversity of microbial samples, including water, sediment, biofilm, and floating microbial mats collected from a laboratory mesocosm as well as from streams, lakes, and wetlands in Georgia and Florida. The decreasing order of… Expand
Quantitative assessment of the effects of metals on microbial degradation of organic chemicals
TLDR
Effects of heavy metals on aerobic microbial degradation rates of organic chemicals appeared to be considerably more inhibitory to the biodegradation of an organic chemical than high concentrations of microbially toxic organics studied previously. Expand
The effect of algal blooms on the disappearance of phenol in a small forest pond
TLDR
During the periods of “blooms” of the green algae in the pond the concentrations of inorganic nutrients were comparatively high and the phenol-degrading bacteria likely were not limited by these nutrients, in contrast to the periods-of-bloom of the blue–green algae on the other hand in the reservoir.

Inoculum Standardization for Biodegradability Tests
To obtain standardized inoculum with constant characteristics for biodegradability test, Actizym powder was used instead of sludge. A predigestion and stabilization step were introduced to prepareExpand

Predicting 2,4-Dichlorophenoxyacetic Acid Ester Transformation Rates in Periphyton-Dominated Ecosystems
TLDR
Using batch cultures, transformation rate coefficients for microbial transformation of 2,4-dichlorophenoxyacetic acid butoxyethyl ester in periphyton-dominated ecosystems were determined and mean second-order rate coefficients were used to predict 2, 4-DBE transformation rates in microcosms having diverse chemical and biological environments.

TLDR
Under conditions of mass transport limitation, the contributions of attached microorganisms relative to total microbial activities at various field sites were related to the ratio of water velocity, U, and depth, D, showing that historical definitions of ecosystems according to flow and depth characteristics are also valid for describing the process-related structure of ecosystems.

TLDR
Using batch cultures, transformation rates for low concentrations of two toxicants are determined by aufwuchs, aquatic microbial growth attached to submerged surfaces or suspended in streamers or mats, for potential use in a mathematical model capable of predicting the transport and fate of chemicals in aquatic systems.

Kinetic Concepts for Measuring Microbial Rate Constants: Effects of Nutrients on Rate Constants
TLDR
The use of nutrient-amended waters could be a useful tool for estimating second-order rate constants for an expanded number of compounds, and this technique would provide a larger data base for predicting the behavior of xenobiotic compounds in the environment by using currently available mathematical models.

Microbial Transformation of Esters of Chlorinated Carboxylic Acids
TLDR
The microbial rate constants of the carboxylic acid esters with a fixed aromatic moiety increased with an increasing length of alkyl substituents, and the regression coefficient for the linear relationships between log k(b) and log K(ow) was high for group 1 compounds, indicating that these parameters correlated well.
