Marinobacterium sp. strain DMS-S1 is a unique marine bacterium that can use dimethyl sulphide (DMS) as a sulphur source only in the presence of light. High-performance liquid chromatography (HPLC) analyses of the culture supernatant revealed that excreted factors, which could transform DMS to dimethyl sulphoxide (DMSO) under light, are FAD and riboflavin. In addition, FAD appeared to catalyse the photolysis of DMS to not only DMSO but also methanesulphonate (MSA), formate, formaldehyde and sulphate. As strain DMS-S1 can use sulphate and MSA as a sole sulphur source independently of light, the excretion of flavins appeared to support the growth on DMS under light. Furthermore, three out of 12 marine bacteria from IAM culture collection were found to be able to grow on DMS with the aid of photolysis by the flavins excreted. This is the first report that bacteria can use light to assimilate oceanic organic sulphur compounds outside the cells by excreting flavins as photosensitizers.
