Paecilomyces sp. TLi, a coal-solubilizing fungus, was shown to degrade organic sulfur-containing coal substructure compounds. Dibenzothiophene was degraded via a sulfur-oxidizing pathway to 2.2'-biphenol. No further metabolism of the biphenol was observed. Ethyl phenyl sulfide and phenyl sulfide were degraded to the corresponding sulfones. A variety of products were formed from benzyl sulfide, presumably via free radical intermediates. Phenyl disulfide and benzyl disulfide were cleaved to the corresponding thiols and other single-ring products. It was concluded that degradation of organic sulfur compounds by Paecilomyces involves an oxidative attack localized at the sulfur atom. 21 refs., 3 figs., 2 tabs.
