The anaerobic decomposition of benzoic acid during methane fermentation

The aerobic metabolism of cyclohexanecarboxylic acid by Acinetobacter anitratum

“…The hexahydrohippuric acid (cyclohexanoylglycine), detected in the urine of cattle (Suemitsu et al, 1971), may conceivably have arisen from 11-cyclohexylundecanoic acid, shown by Hansen (1967) to be a component of the fatty acids of bovine rumen bacteria. However, in the light of the anaerobic metabolism of benzoate by rumen liquor, described by Clark & Fina (1952) and in the preceding paper (Williams & Evans, 1975), a direct reduction of benzoate (or of the benzoate moiety of hippurate) to cyclohexanecarboxylate is now-a viable alternative origin for this compound. Colla & Treccani (1960) isolated adipic acid and pimelic acid from the culture fluid of a Flavobacterium sp.…”

The Microbiological Degradation of Aromatic Compounds

“…Clarke & Fina (1952) confirmed the utilization of benzoate by methane-producing cultures; catechol and protocatechuate could not be metabolized by these cultures, and exogenous CO, was not reduced mainly to methane. In subsequent tracer studies (Fina & Fiskin, 1960;Roberts, 1962) it was determined that the carboxyl-C and C4 of benzoate behaved the same as exogenous CO,.…”

Heat treatment of organics for increasing anaerobic biodegradability. Annual progress report, June 1, 1976-May 31, 1977. Civil engineering technical report No. 222

“…(1) to verify the potential of the two-stage thermochemical digestion scheme for increasing methane yield from lignocellulose, (2) to develop an anaerobic culture acclimated to products from the alkaline .heat treatment of lignocellulose, and (3) to develop long-term, batch.bioassay techniques for future study with acclimated seed. In addition, the d'igestibility of thermochemicdlly treated lignin was investigated by use of the newly developed long-term assay procedures.…”

“…Mass balances have played a big part in most of the investigations of the methanogenic degradation of simple aromatic compounds (Tarvin and Buswell, 1934;Clark and Fina, 1952;Fina and Fiskin, 1960;Chmielowski et al, 1964;Nottingham and Hungate, 1969;and Ferry and Wolfe, 1976). Chmielowski et al (1964) demonstrated that phenol, p-cresol, resorcinol, and a combination of …”

“…Tarvin and Buswell (1934) obtained mixed cultures from sewage sludge which fermented a range of aromatic compounds to a mixture of C02 and CH4. Clark and Fina (1952) and Fina and Fiskin (1960) used a mixed culture from sewage sludge or rumen fluid and confirmed that benzoate was metabolized to a mixture of C02 and CH4. Barker (1956) described studies in which several aromatic acids were utilized under strictly anaerobic conditions by a heterogeneous population of methanogenic bacteria.…”
