Priming effect of substrate addition in soil-based biodegradation tests
Article Abstract:
Glucose added to the soil in biodegradation tests produces a substrate-stimulated soil organic matter mineralization priming effect that increases the production of CO2. Phenol produces a temporary increase in CO2 production. Formate, benzoate, n-hexadecane, and bis(2-ethylhexyl)phthalate produce no priming effect. The measurement of 14CO2 and net CO2 evolution from different test compounds indicates that the effect of glucose is unique. Thus, benzoate is suitable for use as a control compound in the biodegradation tests while glucose is unsuitable.

Testing of some assumptiions about biodegradability in soil as measured by carbon dioxide evolution
Article Abstract:
Carbon dioxide evolution is used for testing soil biodegradability. Experiments were conducted with unlabeled and radiolabeled substrates to determine the effect of chemmical composition, mode of application, substrate concentrations and carbon dioxide (CO2) evolution on soil microbial community. The utility of net CO2 and CO2 evolution measurements as first tier tests for evaluating soil biodegradability was demonstrated.

Biodegradation of [14C]benzo[a]pyrene added to crude oil to uncontaminated soil
Article Abstract:
The degradation of benzo[a]pyrene (BaP) in conjunction with other hydrocarbons in crude oil admixed with soil was monitored in a controlled environment. Results reveal cometabolic degradation of BaP and hydrocarbons in uncontaminated soil indicating that native bacteria can biotransform BaP in the presence of suitable co-substrates. Further, complete degradation of BaP is possible under this condition.
