“…Several recent studies have suggested various biological methods for the cleanup of TNT-contaminated soil (6,(10)(11)(12)(13). The results of composting studies are encouraging, but the requirement for excavation and transport of the contaminated soil, addition of supplemental carbon, long incubation periods, and in some cases, inoculation with a suitable microbial population make this approach expensive (6).…”

“…Kilbane isolated a pure culture Rhodococcus rhodochrous; research with this microorganism has reported 35% organic sulfur removal [10]. Isbister [11] reported up to 32% organic sulfur removal with a mixed culture CB1, although this has not been found readily repeatable by others [2]. Kargi [12] reported partial removal of organic sulfur by Sulfolobus acidocaldarius, but in other papers no indication is given of organic sulfur removal by the organism [13,14].…”

“…DO producing DBT sulfoxide, DBT sulfone, and benzoate as major intermediates during DBT mineralization. The most extensively studied pathway, the biodesulfurization pathway for DBT (22,25,26,27,31,37), is inhibited by the presence of sulfate and is not likely to contribute to DBT biodegradation in sulfate-containing environments such as the oceans (32).…”

Dibenzothiophene is a sulfur heterocycle found in crude oils and coal. The biodegradation of dibenzothiophene through the Kodama pathway by Pseudomonas sp. strain BT1d leads to the formation of three disulfides: 2-oxo-2-(2-thiophenyl)ethanoic acid disulfide, 2-oxo-2-(2-thiophenyl)ethanoic acid-2-benzoic acid disulfide, and 2,2-dithiodibenzoic acid. When provided as the carbon and sulfur source in liquid medium, 2,2-dithiodibenzoic acid was degraded by soil enrichment cultures. Two bacterial isolates, designated strains RM1 and RM6, degraded 2,2-dithiodibenzoic acid when combined in the medium. Isolate RM6 was found to have an absolute requirement for vitamin B 12 , and it degraded 2,2-dithiodibenzoic acid in pure culture when the medium was supplemented with this vitamin. Isolate RM6 also degraded 2,2-dithiodibenzoic acid in medium containing sterilized supernatants from cultures of isolate RM1 grown on glucose or benzoate. Isolate RM6 was identified as a member of the genus Variovorax using the Biolog system and 16S rRNA gene analysis. Although the mechanism of disulfide metabolism could not be determined, benzoic acid was detected as a transient metabolite of 2,2-dithiodibenzoic acid biodegradation by Variovorax sp. strain RM6. In pure culture, this isolate mineralized 2,2-dithiodibenzoic acid, releasing 59% of the carbon as carbon dioxide and 88% of the sulfur as sulfate.
