Sulfur from benzothiophene and alkylbenzothiophenes supports growth of Rhodococcus sp. strain JVH1

摘要: Rhodococcus sp. strain JVH1 was previously reported to use a number of compounds with aliphatic sulfide bridges as sulfur sources for growth. We have shown that although does not the three-ring thiophenic compound dibenzothiophene, this can two-ring benzothiophene its sole source, resulting in growth culture and loss benzothiophene. Addition inorganic sulfate medium reduced conversion benzothiophene, indicating metabolism is repressed by therefore used specifically source. also all six isomers methylbenzothiophene two dimethylbenzothiophene Metabolites identified from some methylbenzothiophenes were consistent published pathways biodesulfurization. Products retaining atom sulfones sultines, sultines being formed phenolic sulfinates under acidic extraction conditions. With 2-methylbenzothiophene, final desulfurized product 2-methylbenzofuran, dehydration 3-(o-hydroxyphenyl) propanone conditions an oxygenative desulfination reaction. 3-methylbenzothiophene, 2-isopropenylphenol, hydrolytic first microorganism methylbenzothiophene, well isomers, sources. possesses broader abilities than reported, including only sulfidic but species.
