Isomers by Methanogenic Consortia Anaerobic Degradation of Phthalate

Anaerobic degradation of halogenated phenols by sulfate-reducing consortia.

Sulfidogenic consortia enriched from an estuarine sediment were maintained on either 2-, 3-, or 4-chlorophenol as the only source of carbon and energy for over 5 years. The enrichment culture on 4-chlorophenol was the most active and this consortium was selected for further characterization. Utilization of chlorophenol resulted in sulfate depletion corresponding to the values expected for compl...

Interspecies acetate transfer influences the extent of anaerobic benzoate degradation by syntrophic consortia.

Benzoate degradation by an anaerobic, syntrophic bacterium, strain SB, in coculture with Desulfovibrio sp. strain G-11 reached a threshold value which depended on the amount of acetate added and ranged from about 2.5 to 29.9 (mu)M. Increasing acetate concentrations also uncompetitively inhibited benzoate degradation. The apparent V(infmax) and apparent K(infm) for benzoate degradation decreased...

Vitamin and Amino Acid Auxotrophy in Anaerobic Consortia Operating under Methanogenic Conditions

Syntrophy among Archaea and Bacteria facilitates the anaerobic degradation of organic compounds to CH4 and CO2. Particularly during aliphatic and aromatic hydrocarbon mineralization, as in the case of crude oil reservoirs and petroleum-contaminated sediments, metabolic interactions between obligate mutualistic microbial partners are of central importance. Using micromanipulation combined with s...
