Formation of hydride-Meisenheimer complexes of picric acid (2,4,6-trinitrophenol) and 2,4-dinitrophenol during mineralization of picric acid by Nocardioides sp. strain CB 22-2
Article Abstract:
A strain that was able to use picric acid as a sole source of carbon and energy at certain concentrations and rates in continuous cultures was isolated and characterized for the first time. A Nocardioides sp. strain, CB 22-2 completely mineralizes picric acid with intermediate formation of the (H(super -))-Meisenheimer complexes (2,4,6-trinitrophenol) (H(super -)-TNP) and 2,4-dinitrophenol (H(super -)-DNP). The strain was also found to be able to use picric acid as a sole source of nitrogen at comparable rates in a nitrogen-free medium.

Stability and performance of Xanthobacter autotrophicus GJ10 during 1,2-dichloroethane biodegradation
Article Abstract:
A nucleic acid-based approach was used to investigate the dynamics of microbial community dominated by Xanthobacter autotrophicus GJ10 in the degradation of synthetic wastewater containing 1,2-dichloroethane (DCE). The study was performed over a 140-day period in a nonsterile continuous stirred tank bioreactor (CSTB) subjected to different operational regimens such as nutrient limiting conditions, baseline operation and the introduction of glucose as a cosubstrate.

Evidence of substantial carbon isotope fractionation among substrate, inorganic carbon, and biomass during aerobic mineralization of 1,2-dichloroethane by Xanthobacter autotrophicus
Article Abstract:
Carbon isotope fractionation can be used to detect microbial breakdown of 1,2-dichloroethane in groundwater. This technique relies on the fact that biotic transformation often involves a kinetic isotope effect whereby the precursor and product have different isotope ratios.
