The use of stable sulfur isotope labelling to elucidate sulfur metabolism by Clostridium pasteurianum

|September 1, 1976
Abstract:
An unique isotope labelling experiment was conducted whereby mixtures of sulfate and sulfite of different isotopic compositions were metabolized by Clostridium pasteurianum. The results showed during reduction of 1 mM SO3= plus 1 mM SO4=, essentially all evolved H2S arose from the sulfite whereas in the case of cellular sulfur, 85% was derived from sulfite and the remainder from sulfate.
