ATP sulfurylase activity of sulfate-reducing bacteria from various ecotopes.

ABSTRACT: Sulfate-reducing bacteria (SRB) are widespread in various ecotopes despite their growth and enzymatic features not compared. In this study, the enzymatic parameters of ATP sulfurylase in cell-free extracts of sulfate-reducing bacteria isolated from various ecotopes such as soils, corrosion products and human large intestine were determined. Comparative analysis of both enzyme characteristics and growth parameters were carried out and similar research has not been reported yet. The initial and maximum rates of enzymatic reaction catalyzed by ATP sulfurylase were significantly different (p < 0.05) in the bacterial strains isolated from various environmental ecotopes. The specific activity of this enzyme in sulfate-reducing bacteria was determined for corrosive and intestinal strains 0
