Abstract

In extracts ofThiocapsa floridana strain 6311 andChromatium strains 1611, 2811 and 6412 a high specific activity of adenosine 5′-phosphosulfate reductase was found. In contrast, little activity of this enzyme was found inChromatium strain D.

Adenosine 5′-diphosphate sulfurylase is present in extracts fromThiocapsa floridana strain 6311. The enzyme appears to be involved in the oxidation of reduced sulfur compounds to sulfate.

Sulfite oxidase could not be demonstrated in any of the strains examined.
