Substrate interactions during the anaerobic biodegradation of 1,1,1-trichloroethane
… is the most important mechanism for the anaerobic biodegradation of highly halogenated aliphatic hydrocarbons. The concentrations of primary electron-donor and -acceptor substrates, which control the intracellular availability of electrons, can affect the rates of these reactions. A …

Evaluation of Anaerobic Biodegradation of Organic Carbon Extracted from Aquifer Sediment
… extracted using this method will biodegrade in anaerobic environments. The ultimate goal is to use this method for the evaluation of chloroethene contaminated sites in order to estimate the long-term sustainability of monitored natural attenuation (MNA) as a remediation strategy. Although …

Anaerobic biodegradation of selected organic compounds with and without inhibition of sulfate reducing bacteria
… substitute or as a reducing equivalent in the anaerobic biodegradation of methanol, methyl tert-butyl ether (MTBE), toluene, phenol, and 2,4- dichlorophenol. In addition, biodegradation rates of these compounds at various initial concentrations with and without inhibition of sulfate reducing …

An investigation of recalcitrant organic compounds in leachates
… In one experiment, a laboratory scale aerobic biodegradation is carried out on four untreated and two treated leachate samples collected from two UK MSW landfills (Pitsea and Rainham), and leachates are characterised using conventional methods (COD and DOC) as well as UV absorption and …

Effects of Capping on Biodegradation of Organic Contaminants in Sediments
… research investigated the effect of capping on biodegradation of organic contaminants in Anacostia River sediments using both experimental and modeling techniques. 14C–Phenanthrene mineralization was monitored under various redox conditions in Anacostia River sediments. Mineralization of …

Biodegradation of Volatile Hydrocarbons in Estuarine Environments
… is not completely elucidated. Aerobic and anaerobic degradation of these VOCs in the Colne estuary, UK, was investigated using both cultivation-dependent and independent approaches, to understand the effect of VOC-type, concentration and estuarine location on degradation and microbial …

A Non-isolated Half Bridge Buck-based Converter For Vrm Application And Small Signal Modeling Of A Non-conventional Two Phase Bu
… will remove refractory compounds that inhibit biodegradation and will produce smaller, more biodegradable organic molecules which will result in an increase in BOD and BMP values. Both BOD and BMP results demonstrated that Fenton's reagent treatment did not convert mature leachate to …

Identification of Genes Induced under Anaerobic Benzene-Oxidizing Conditions in Dechloromonas aromatica strain RCB
… attenuation of benzene from the environment. Biodegradation of benzene by oxidation can occur under aerobic, anaerobic and microaerophilic conditions. Biooxidation of benzene under aerobic conditions is well-studied. However, oxygen is scarce in contaminated subsurface environments, and after …

IMPROVING THE CIRCULARITY OF BIODEGRADABLE BIOPLASTICS BY PRODUCING BIOGAS: A FULL-SCALE ASSESSMENT
… alternative to conventional plastics. Their anaerobic co-digestion with the organic fractions of municipal solid waste (OFMSW) is a promising end-of-life scenario, as it reduces pre-treatment and increases process efficiency and biogas production. However, PLA shows poor biodegradability …

Elevated temperatures in waste containment facilities
… above 65°C is considered to be elevated because anaerobic decomposition has been curtailed. Several factors can lead to elevated landfill temperatures, including aerobic decomposition, self-heating, partially extinguished surface fires, exothermic chemical reactions, and spontaneous combustion. …

The Microbubble Assisted Bioremediation of Chlorinated Ethenes
… to deliver hydrogen and carbon dioxide to anaerobic consortia to stimulate their ability to reductively dehalogenate tetrachloroethylene all the way to ethene and ethane. A continuous flow system, consisting of six anaerobic soil column bioreactors, inoculated with sediments from Virginia …
