Methane fermentation of ferulate and benzoate: anaerobic degradation pathways.
The anaerobic biodegradation of ferulate and benzoate in stabilized methanogenic consortia was examined in detail. Up to 99% of the ferulate and 98% of the benzoate were converted to carbon dioxide and methane. Methanogenesis was inhibited with 2-bromoethanesulfonic acid, which reduced the gas production and enhanced the buildup of intermediates. Use of high-performance liquid chromatography an...
متن کاملRuminal Fermentation of Anti-Methanogenic Nitrate- and Nitro-Containing Forages In Vitro
Nitrate, 3-nitro-1-propionic acid (NPA) and 3-nitro-1-propanol (NPOH) can accumulate in forages and be poisonous to animals if consumed in high enough amounts. These chemicals are also recognized as potent anti-methanogenic compounds, but plants naturally containing these chemicals have been studied little in this regard. Presently, we found that nitrate-, NPA-, or NPOH-containing forages effec...
متن کاملMethanogenic fermentation of the naturally occurring aromatic amino acids by a microbial consortium.
Medium 2 was similar to Medium 1 except for the replacement of sodium lactate by sodium benzoate (0.75 9). Sterile culture flasks (500ml) were filled to the brim with freshly prepared sterile Medium 1 and 2 separately, inoculated with a suspension of freeze-dried Desulfovibrio N.C.I.B. 8399, capped with sterile Suba-Seal rubber stoppers and incubated by total immersion in a water bath at 37°C. ...
متن کاملFermentation Enhancement of Methanogenic Archaea Consortia from an Illinois Basin Coalbed via DOL Emulsion Nutrition
Microbially enhanced coalbed methane technology must be used to increase the methane content in mining and generate secondary biogenic gas. In this technology, the metabolic processes of methanogenic consortia are the basis for the production of biomethane from some of the organic compounds in coal. Thus, culture nutrition plays an important role in remediating the nutritional deficiency of a c...
متن کاملBenzoate fermentation by the anaerobic bacterium Syntrophus aciditrophicus in the absence of hydrogen-using microorganisms.
The anaerobic bacterium Syntrophus aciditrophicus metabolized benzoate in pure culture in the absence of hydrogen-utilizing partners or terminal electron acceptors. The pure culture of S. aciditrophicus produced approximately 0.5 mol of cyclohexane carboxylate and 1.5 mol of acetate per mol of benzoate, while a coculture of S. aciditrophicus with the hydrogen-using methanogen Methanospirillum h...
