Genthner, Barbara R. Sharak published the artcileReduction of 3-chlorobenzoate, 3-bromobenzoate, and benzoate to corresponding alcohols by Desulfomicrobium escambiense, isolated from a 3-chlorobenzoate-dechlorinating coculture, Product Details of C8H7ClO4, the main research area is Desulfomicrobium chlorobenzoate bromobenzoate benzoate reduction.
An anaerobic bacterial coculture which dechlorinated 3-chlorobenzoate (3CB) to benzoate was obtained by single-colony isolation from an anaerobic bacterial consortium which completely degraded 3CB in defined medium. Of 29 addnl. halogenated aromatic compounds tested, the coculture removed the meta halogen from 2,3- and 2,5-dichlorobenzoate, 3-bromobenzoate (3BB), 5-chlorovanillate (5CV), and 3-chloro-4-hydroxybenzoate. Dechlorinating activity in the coculture required the presence of pyruvate. 5CV was also O-demethoxylated. The coculture contained two cell types: a short, straight gram-neg. rod and a long, thin, curved gram-pos. rod. The short rod, Desulfomicrobium escambiense, was recently isolated and identified as a new sulfate-reducing bacterial species (B. R. Sharak Genthner, S. D. Friedman, and R. Devereux, Int. J. Syst. Bacteriol. 47:889-892, 1997; B. R. Sharak Genthner, G. Mundfrom, and R. Devereux, Arch. Microbiol. 161:215-219, 1994). D. escambiense did not dehalogenate any of the compounds dehalogenated by the coculture, nor did it O-demethoxylate 5CV or vanillate. However, D. escambiense reduced 3CB, 3BB, and benzoate to their resp. benzyl alcs. Reduction to alcs. required the presence of pyruvate, which was transformed to acetate, lactate, and succinate in the presence or absence of 3CB, 3BB, or benzoate. Alc. formation did not occur in pyruvate-sulfate medium. Under these conditions, sulfate was preferentially reduced. Other electron donors that supported the growth of D. escambiense during sulfate reduction did not support benzoate reduction to benzyl alc.
Applied and Environmental Microbiology published new progress about Desulfomicrobium escambiense. 62936-23-6 belongs to class chlorides-buliding-blocks, name is 3-Chloro-4-hydroxy-5-methoxybenzoic acid, and the molecular formula is C8H7ClO4, Product Details of C8H7ClO4.
