Sulfur can be removed from benzothiophene (BT) by some bacteria without breaking carbon-carbon bonds. However, a clear mechanism for BT desulfurization and its genetic components have not been reported in literatures so far. In this study, we used comparative transcriptomics to study differential expression of genes in Gordonia terrae C-6 cultured with BT or sodium sulfate as the sole source of...

Cells of Gordonia nitida LE31 grown on 3-methylpyridine degraded 3-ethylpyridine without a lag time and vice versa. Cyclic intermediates were not detected, but formic acid was identified as a metabolite. Degradation of levulinic acid was induced in cells grown on 3-methylpyridine and 3-ethylpyridine. Levulinic aldehyde dehydrogenase and formamidase activities were higher in cells grown on 3-met...

Statistically based experimental designs were used to construct a mixedculture community for maximizing the chemical oxygen demand (COD) degradation of pulping effluents by the use of six different strains, i.e., Agrobacterium sp., Bacillus sp., Enterobacter cloacae, Gordonia, Pseudomonas stutzeri, and Pseudomonas putida. Significant effects of single and mixed strains on COD degradation were q...

Actinomycetes that have mycolic acid in the cell walls have been classified under genera such as Corynebacterium, Gordonia, Mycobacterium, Nocardia, Rhodococcus, Tsukamurella, Skermania and Williamsia [1]. Williamsia was introduced in 1999 by Kämpfer et al. [2] to accommodate actinomycetes with atypical cell morphology and mycolic acids with 50 to 56 carbon chain lengths between the genera of R...

Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9.0. The most effective dehalogenase activity for 1-chlorobutane conversion was detected with Rhodococcus erythropolis NCIMB13064 and Escherichia...

Gordona terrae strain C-6 was isolated from oil-contaminated soil and is capable of desulfurizing benzothiophene (BT). Here we report the draft genome sequence of G. terrae strain C-6, which may help to reveal the genetic basis of the BT biodesulfurization pathway.
