Popis:	Culture conditions were evaluated for their relevance to chemical and biological oxidation of sulphide in aqueous solution. With a mixed culture of colourless sulphur bacteria sulphide oxidation was investigated over a concentration range of 0.005 to 3.5 mm S2−, a pH range from 1.0 to 9.0 and temperatures from 10 to 40° C. Biological sulphide oxidation quickly decreased when fermentation conditions were suboptimal and the proportion of chemical oxidation increased with high pH values and sulphide concentration and increasing temperature. The optimal conditions for biological activity were found to be 3 mm S2−, pH 7.0, and a mesophilic temperature (40° C).
