	abstract = {<p>4-Methylphenol (4-MP), a putative bisphenol A (BPA) degradation intermediate, was detected at concentrations reaching 2.1 mg L(-1) in anoxic microcosms containing 10 mg L(-1) BPA and 5 g of freshwater sediment material collected from four geographically distinct locations and amended with nitrate, nitrite, ferric iron, or bicarbonate as electron acceptors. 4-MP accumulation was transient, and 4-MP degradation was observed under all redox conditions tested. 4-MP was not detected in microcosms not amended with BPA. Unexpectedly, incubations with (13)C-labeled BPA failed to produce (13)C-labeled 4-MP suggesting that 4-MP was not derived from BPA. The detection of 4-MP in live microcosms amended with lactate, but not containing BPA corroborated that BPA was not the source of 4-MP. These findings demonstrate that the transient formation of 4-MP as a possible BPA degradation intermediate must be interpreted cautiously, as microbial activity in streambed microcosms may generate 4-MP from sediment-associated organic material.</p>},

	abstract = {The transfer of the methyl group of acetate to coenzyme M (2-mercaptoethanesulfonic acid; HS-CoM) during the metabolism of acetate to methane was investigated in cultures of Methanosarcina strain TM-1. The organism metabolized CD3COO- to 83\% CD3H and 17\% CD2H2 and produced no CDH3 or CH4. The isotopic composition of coenzyme M in cells grown on CD3COO- was analyzed with a novel gas chromatography-mass spectrometry technique. The cells contained CD3-D-CoM and CD2H-S-CoM) in a proportion similar to that of CD3H to CD2H2. These results, in conjunction with a report (J.K. Nelson and J.G. Ferry, J. Bacteriol. 160:526-532, 1984) that extracts of acetate-grown strain TM-1 contain high levels of CH3-S-CoM methylreductase, indicate that CH3-S-CoM is an intermediate in the metabolism of acetate to methane in this organism.},
