Title
Enhancing denitrifying sulfide removal with functional strains under micro-aerobic condition
Abstract

The biological denitrifying sulfide reaction (DSR) frequently proceeds in anaerobic environments since excess oxygen inhibits the activity of the denitrifiers. This study isolated a consortium H7, comprising two strains, Penibacillus sp. and Aneurinibacillus aneurinilyticus. It indicated that the DSR performance with the H7 in a mixotrophic medium is significantly enhanced at high sulfide concentrations. The H7 was inhibited by adding >200 mg l−1 of S2− under anaerobic conditions. However, when 280 mg −1 of S2− was added, H7 could still degrade some of the sulfide, nitrate and acetate under micro-aerobic conditions. Micro-aerobic conditions stimulated the activity of sulfide oxidase and increased the removal rate of highly concentrated sulfide, reducing the inhibition of sulfide on denitrifiers and improving DSR performance.
