A photosynthetic bioconversion process is described for removal of sulfur compounds from a gas stream comprising carbon oxide and reductive sulfur compounds. The process comprises: contacting the gas stream consisting of carbon oxide compounds and reductive sulfur compounds with an active culture of photosynthetic bacteria capable of utilizing the reductive sulfur compound as its sole source of reducing electrons and the carbon oxides as its sole source of carbon for growth under substantially anaerobic conditions with electromagnetic radiation. The reductive sulfur compound provides the sole source of reducing electrons and the carbon oxides provide the sole source of carbon for growth and cultivating the bacteria to form elemental sulfur and organic carbon compounds.
