Inorganic Sulfur Oxidation by Aureobasidium pullulans

Abstract

Aureobasidium pullulans (de Bary) Arnaud isolated from the phylloplane of sycamore exposed to heavy atmospheric pollution oxidized S0 to S2O32−, S4O62−, and SO42− in vitro. The intermediates S2O32− and S4O62− were also oxidized to SO42−. Cell-free extracts of A. pullulans also oxidized reduced forms of S, the oxidation increasing linearly with increasing protein concentration, showing that the process is enzymatic. The possible role of fungi in S oxidation in soils is discussed.
