A fractionation of sulphur isotopes was found in all hetabolic processes investigated except those in which elemental sulphur was the starting substrate for growth of Thiobacillus concretivorus and Chromatiurn sp. and for reduction by Saccharomyces cerevisiae. Except for polythionates formed during sulphide oxidation by T. concretivorus or Chromatiurn sp., the products of metabolism were enrich...
