Biostimulation and bioaugmentation enhances aerobic biodegradation of dichloroethenes
Chemosphere, 2006The accumulation of dichloroethenes (DCEs) as dominant products of microbial reductive dechlorination activity in soil and water represent a significant obstacle to the application of bioremediation as a remedial option for chloroethenes in many contaminated systems.

COMPUTER-AUTOMATED PREDICTIONS OF AEROBIC BIODEGRADATION OF CHEMICALS
Environmental Toxicology and Chemistry, 1995Abstract A computer program has been developed that can predict the most probable metabolites formed from aerobic biodegradation of chemicals. Predictions are based on an expert evaluation of the parent chemical's molecular structure. The program was designed to recognize molecular fragments within complete chemical structures that are ...

AEROBIC BIODEGRADATION OF MONOBRANCHED ALIPHATIC ALCOHOL POLYETHOXYLATES
Environmental Toxicology and Chemistry, 2000Abstract Aerobic biodegradation of the 2-butyl-octyl alcohol polyethoxylate (2Bu-C8AE) was investigated under laboratory standardized conditions (Organization for Economic Cooperation and Development 301E and 310B screening test protocols) to study the effect of the 2-alkyl chain length on the biodegradation mechanism of monobranched ...

Strategies for the Aerobic Biodegradation of Dinitrotoluenes
1999Dinitrotoluenes (DNT) are intermediates in the production of the explosive 2,4,6-trinitrotoluene (TNT) and precursors of toluenediisocyanate used in the manufacture of polyurethane foams (Hartter, 1985) Disposal practices associated with TNT manufacturing dating back to World Wars I and II, have resulted in an enormous contamination problem at ...

Environmental Toxicology and Chemistry, 1997
AbstractIt is shown that a combination of two programs, MultiCASE and META, can help assess the biodegradability of industrial organic materials in the ecosystem. MultiCASE is an artificial intelligence computer program that had been trained to identify molecular substructures believed to cause or inhibit biodegradation and META is an expert system ...

Aerobic biodegradation of nonylphenol by cold-adapted bacteria
Biotechnology Letters, 2003Three strains capable of mineralizing nonylphenol as sole carbon source were isolated from a sample of contaminated soil and characterized as two Pseudomonas spp. and a Stenotrophomonas sp. The two Pseudomonas spp. expressed characteristics typical of psychrophiles growing optimally of 10 degrees C and capable of growing at 0 degree C.

Aerobic biodegradation of amines in industrial saline wastewaters
Chemosphere, 2011The treatment of hypersaline wastewaters represents a challenge since high salt concentrations disrupt bacteria present in normal biological treatments. This study was conducted to determine the fate of amines in two hypersaline wastewaters obtained from an industrial treatment plant processing influents with 3% and 7% of NaCl.

p-Nitrophenol Biodegradation by Aerobic Microbial Granules
Applied Biochemistry and Biotechnology, 2012Mixed microbial consortia in the form of aerobic microbial granules (AMG) capable of xenobiotic degradation can be developed from activated sludge or by adaptation of microbial granules pre-grown on labile carbon sources. Both of these approaches were investigated for the cultivation of AMG capable of p-nitrophenol (PNP) biodegradation.
