A mathematical model composed of a direct proportionality relationship between bulk water velocities and field-determined second-order microbial transformation rate coefficients, and the relative rate coefficient of a benchmark chemical, was developed for estimating the substrate removal rates of rapidly degraded chemicals by attached organisms in shallow (<1 m deep) aquatic ecosystems. Data from 31 field experiments involving the addition of 2,4-dichlorophenoxyacetic acid methyl ester (2,4-DME… 

Initial Test of the Benchmark Chemical Approach for Predicting Microbial Transformation Rates in Aquatic Environments

Overall, the data indicated that microbial transformation rates of a chemical can be satisfactorily inferred for a wide variety of microbial habitats-such as water, biofilm, or a sediment-on the basis of its transformation rate relative to that of an appropriate benchmark chemical by using a single type of microbial sample.

Quantitative assessment of the effects of metals on microbial degradation of organic chemicals

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.

Nutrient effects on microbial transformation of pesticides in nitrifying surface waters

Multivariate analyses of a large set of physical, chemical, and biological measurements indicated possible effects that specific surface water properties have on biotransformation rates of

Transformation processes of contaminants in rivers

The paper reviews the expressions used to predict the rates of transformation of organic contaminants in surface waters. The application of these expressions to determine transformation rates of

Fluorescent pseudomonas isolates from Mississippi Delta oxbow lakes: In vitro herbicide biotransformations

Results indicate that reductive and hydrolytic pathways for herbicide co‐metabolism (aromatic nitroreduction, aryl acylamidase, and glutathione conjugation) are common in Mississippi Delta aquatic fluorescent pseudomonads; however, the potential for certain oxidative transformations (N‐dealkylation, cyano group oxidation) may be rare in this group of bacterioplankton.

Predicting 2,4-Dichlorophenoxyacetic Acid Ester Transformation Rates in Periphyton-Dominated Ecosystems

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.

Decomposition by planktonic and attached microorganisms improves chemical fate models

Terms for decomposition by both suspended and attached microorganisms were included in a model to calculate the fate of chemicals in aquatic systems. This model differs from previous models primarily

Seasonal effects on microbial transformation rates of an herbicide in a freshwater stream: Application of laboratory data to a field site

The increased winter transformation rates were associated with leaf-litter accumulation, which provided additional colonized surface area in the stream, which more than compensated for the effects of temperature and water velocity that otherwise would have reduced microbial transformation rates in the winter months.

Second-Order Model to Predict Microbial Degradation of Organic Compounds in Natural Waters

The reliability of second-order rate constants for assessing microbial degradation kinetics in natural waters was examined by using three compounds that undergo hydrolytic degradation, and indicated that the rate conformed to second- order kinetics.

Models for the kinetics of biodegradation of organic compounds not supporting growth

It is concluded that the kinetics of mineralization of organic compounds at concentrations too low to support growth are best described either by the first-order model or by models that incorporate expressions for the kinetic of growth of the metabolizing population on other substrates.

Application of single‐ and multiphasic michaelis‐menten kinetics to predictive modeling for aquatic ecosystems

The transport, fate and effects of many toxic chemicals in aquatic ecosystems are largely mediated by microbial transformations. In our research, we have assumed that the transformations are a result

Effects of microbial community interactions on transformation rates of xenobiotic chemicals

Inhibition resulted from treatments that lowered the pH, and stimulation resulted from an increase in cell biomass and from a different process whereby rates of transformation per bacterial cell rapidly increased as much as 10-fold.

Kinetics of carbon dioxide uptake by phytoplankton at high pH1

When phytoplankton assimilate CO, at the low concentrations existing at high pI1 their uptake rates may be limited by diffusion transport. Dehydroxylation of IICO, to CO, will, however, reduce the

Microbial Transformation of Esters of Chlorinated Carboxylic Acids

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.
