Microbial transformation of nitroaromatic compounds under anaerobic conditions.
The transformation of several mono- and dinitroaromatic compounds (tested at 50-200 microM) by methanogenic bacteria, sulphate-reducing bacteria and clostridia was studied. Some of the nitroaromatics tested were transformed chemically by 1.5 mM quantities of culture media reducing agents, like cysteine or sulphide. This abiotic reduction occurred at the o-nitro-groups preferentially. Nitropheno...
متن کاملBiodegradation of nitroaromatic compounds.
Nitroaromatic compounds are released into the biosphere almost exclusively from anthropogenic sources. Some compounds are produced by incomplete combustion of fossil fuels; others are used as synthetic intermediates, dyes, pesticides, and explosives. Recent research revealed a number of microbial systems capable of transforming or biodegrading nitroaromatic compounds. Anaerobic bacteria can red...
متن کاملApplication of immobilized microbial cells in biological treatment of contaminated effluent with aromatic compounds: a review article
Background and Objective: Bioremediation of contaminants by living microorganisms is a favorable method for elimination or degradation of pollutants to less harmful substances. In the recent decades, cell immobilization technique has been applied to improve biodegradation efficiency and also overcome to free cells disadvantages. The purpose of this review article is to investigate the applicati...
متن کاملRole of organic matter in microbial transport during irrigation with sewage effluent.
Reduction of migration of fecal coliforms (FC) and streptococci (FS) by limiting the leaching in effluent-irrigated soil was tested in lysimeters packed with quartz sand without or with added biosolids compost or with one of two clayey soils. The 200-L, 70-cm-deep lysimeters were either planted with a Eucalyptus camaldulensis or an Oroblanco citrus tree (in the sand only), or not planted. The E...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
