Sulfide oxidation under chemolithoautotrophic denitrifying conditions
The results of this study indicate the potential of chemolithotrophic denitrification for the removal of hydrogen sulfide, as the sulfide/nitrate ratio can be used to control the fate of sulfide oxidation to either elemental sulfur or sulfate. Expand
Microbial transformation and degradation of polychlorinated biphenyls.
Higher chlorinated biphenyls therefore are potentially fully biodegradable in a sequence of reductive dechlorination followed by aerobic mineralization of the lower chlorinated products. Expand
Biodegradation of polycyclic aromatic hydrocarbons by new isolates of white rot fungi
Biodegradation of PAH by the various strains was highly correlated to the rate by which they decolorized Poly R-478 dye, demonstrating that ligninolytic indicators are useful in screening for promising PAH-degrading white rot fungal strains. Expand
Biodegradability of chlorinated solvents and related chlorinated aliphatic compounds
The biodegradability of chlorinated methanes, chlorinated ethanes, chlorinated ethenes, chlorofluorocarbons (CFCs), chlorinated acetic acids, chlorinated propanoids and chlorinated butadienes wasExpand
Microbial degradation of chlorinated phenols
Chlorophenols have been introduced into the environment through their use as biocides and as by-products of chlorine bleaching in the pulp and paper industry. Chlorophenols are subject to bothExpand

The results suggest that this single isozyme produced in manganese-free cultures of Bjerkandera sp. Expand
Chemolithotrophic denitrification with elemental sulfur for groundwater treatment.
Comparison of bioreactor results with batch kinetic studies revealed that denitrification rates were dependent on the surface area of the added S0, which was determined to be 26.4 mmol /(m2 S0 d). Expand
Anaerobic biotransformation of roxarsone and related N-substituted phenylarsonic acids.
It is demonstrated that roxarsone is rapidly transformed in the absence of oxygen to the corresponding aromatic amine, 4-hydroxy-3-aminophenylarsonic acid (HAPA), the first report of a biologically catalyzed rupture of the phenylarsic group under anaerobic conditions. Expand
Toxicity of N-substituted aromatics to acetoclastic methanogenic activity in granular sludge
It was observed that at any given log P, N-substituted phenols had a toxicity that was 2 orders of magnitude higher than that of chlorophenols and alkylphenols, which indicates that toxicity due to the chemical reactivity of nitroaromatics is much more important than partitioning effects in bacterial membranes. Expand
Toxicity of copper(II) ions to microorganisms in biological wastewater treatment systems.
The results of the batch bioassays indicated that copper(II) caused severe inhibition of key microbial populations in wastewater treatment systems, and denitrifying and nitrifying bacteria showed considerable recovery of their metabolic activity after only several days of exposure to high copper levels.
