Sulfur isotope fractionation during the oxidation of elemental sulfur by thiobacilli in a Solonetzic soil.

Abstract

The oxidation rate of elemental S added to a Solonetzic soil was compared between an uninoculated soil and soils inoculated with two species of thiobacilli. Twelve weeks after S was added, 24% was oxidized to soluble S anions in the uninoculated soil, 34% in soil inoculated with Thiobacillus thiooxidans, and 84% in soil inoculated with Thiobacillus thiparus.-from Authors
