Anaerobic biodegradation of monochlorophenols
Environmental Technology Letters, 1987Abstract Anaerobic degradation of 2‐, 3‐, and 4‐chlorophenol, with and without phenol supplementation, was investigated. 2‐Chlorophenol was readily degraded and mineralized at concentrations as high as 285 mg L‐1. However, 3‐ and 4‐chlorophenol were only degraded after very long acclimation times.

Algal biomass anaerobic biodegradability
Journal of Applied Phycology, 2012We conducted a series of biodegradation studies using microalgae (Arthrospira maxima and Nannochloropsis sp.) and macroalgae (Gelidium corneum and Cladophora glomerata) to elucidate algal biodegradability in wastewater sludge under anaerobic conditions. Algal biodegradability was evaluated according to ASTM D5210-92. The results indicate that A. maxima

Biodegradation of xenobiotics by anaerobic bacteria
Applied Microbiology and Biotechnology, 2005Xenobiotic biodegradation under anaerobic conditions such as in groundwater, sediment, landfill, sludge digesters and bioreactors has gained increasing attention over the last two decades. This review gives a broad overview of our current understanding of and recent advances in anaerobic biodegradation of five selected groups of xenobiotic compounds ...

Isotopic fractionation indicates anaerobic monochlorobenzene biodegradation
Environmental Toxicology and Chemistry, 2005Abstract The concentration and isotopic composition of monochlorobenzene (MCB) was monitored in the plume of an anaerobic, contaminated aquifer in Bitterfeld, Germany. An enrichment in the carbon isotopic composition of more than 4 δ units was found at the fringes of the plume relative to the center (-26.5 ‰), suggesting the occurrence ...

Anaerobic benzene biodegradation—a new era
Research in Microbiology, 2002Benzene is biodegraded in the absence of oxygen under a variety of terminal electron-accepting conditions. However, the mechanism by which anaerobic benzene degradation occurs is unclear. Phenol and benzoate have been consistently detected as intermediates of anaerobic benzene degradation, suggesting that the hydroxylation of benzene to phenol is one ...

Anaerobic Biodegradation of Pesticides
2019With the exception of those used in paddy rice, pesticides are typically applied to oxic environments but may be transported to anoxic environments through leaching, surface runoff, or eroded sediments. Pesticides are often applied to sites subject to transient flooding, eventually causing soil to become anoxic as oxygen consumptions rates exceed ...

Biodegradability of leathers through anaerobic pathway
Waste Management, 2007Leather processing generates huge amounts of both solid and liquid wastes. The management of solid wastes, especially tanned leather waste, is a challenging problem faced by tanners. Hence, studies on biodegradability of leather become imperative. In this present work, biodegradability of untanned, chrome tanned and vegetable tanned leather under ...

Anaerobic biodegradation of surrogate naphthenic acids
Water Research, 2016Surface bitumen extraction from the Alberta's oil sands region generates large settling basins known as tailings ponds. The oil sands process-affected water (OSPW) stored in these ponds contain solid and residual bitumen-associated compounds including naphthenic acids (NAs) that can potentially be biodedgraded by indigenous tailings microorganisms ...

Anaerobic biodegradation of sugar beet pulp
Biodegradation, 2000Sugar beet pulp is a by-product of sugar production and consists mainly of cellulose, hemicellulose and pectin. Its composition is suitable for biological degradation. A possible alternative for the utilization of this material (besides cattle feeding) can be anaerobic methanogenic degradation. It has an additional advantage--biogas production.

Anaerobic biodegradation of saturated and aromatic hydrocarbons
Current Opinion in Biotechnology, 2001Saturated and aromatic hydrocarbons are wide-spread in our environment. These compounds exhibit low chemical reactivity and for many decades were thought to undergo biodegradation only in the presence of free oxygen. During the past decade, however, an increasing number of microorganisms have been detected that degrade hydrocarbons under strictly ...
