Rhodococcus rhodochrous strain IGTS8 metabolizes dibenzothiophene, a model compound for organic sulfur in fossil fuels, in a sulfur-specific manner. Two routes of desulfurization have been identified. Under growth conditions, the intermediates are dibenzothiophene sulfoxide, dibenzothiophene sulfone, 2'-hydroxybiphenyl-2-sulfonate, and 2,2'-dihydroxybiphenyl. Stationary phase cells produce 2-hydroxybiphenyl as the desulfurized product and use the 2'-hydroxybiphenyl-2-sulfinate, rather than the sulfonate, as the key intermediate.
红平红球菌IGTS8菌株以硫特异性方式代谢二苯并噻吩，这是化石燃料中有机硫的一种模型化合物。已确定了两条脱硫途径。在生长条件下，中间产物是二苯并噻吩亚砜、二苯并噻吩砜、2'-羟基联苯-2-磺酸盐和2,2'-二羟基联苯。稳定期细胞产生2-羟基联苯作为脱硫产物，并使用2'-羟基联苯-2-亚磺酸盐而非磺酸盐作为关键中间体。
