The high demand for dyes in the paper, cosmetic, clothing, leather, and food industries drives up use of as a result industrialization. As result, wastewater production from dye manufacturing activities will rise. presence their structural compounds industrial sources place humans, animals plants lives at risk. Synthetic are more challenging to decolorize because they resistant chemical physica...

Dimethylamine was formed from trimethylamine in soils of different pH values. The rate of disappearance of the secondary amine from soil was affected by pH and was markedly reduced under anaerobiosis. The accumulation of dimethylamine in cultures of Micrococcus sp. provided with trimethylamine depended on the nitrogen sources available to the bacterium but was not greatly influenced by the C-N ...

A new procedure was developed for the study of lignin biodegradation by pure or mixed cultures of microorganisms. Natural lignocelluloses were prepared containing C in primarily their lignin components by feeding plants l-[U-C]phenylalanine through their cut stems. Lignin degradation was observed in numerous soils by monitoring evolution of CO(2) from [C]lignin-labeled oak (Quercus albus), mapl...

Passage of agricultural runoff through vegetated drainage ditches has been shown to reduce the amount of pesticides, such as atrazine, exiting out of agricultural watersheds. Previous studies have found that microbial communities in soil from fields treated with atrazine display enhanced rates of atrazine degradation. However, no studies have examined the potential for atrazine degradation in d...

Measurements of biological O(2) demand showed that normal alkanes containing up to 44 carbon atoms were metabolized by microorganisms.
