Abstract
Sulphate-reducing bacteria (SRB) represent a key biological component of the global sulphur (S) cycle and are common in soils, where they reduce SO(4)(2-)to H2S during the anaerobic degradation of soil organic matter. The factors that regulate their distribution in soil, however, remain poorly understood. We sought to determine the ecological patterns of SRB richness within a nationwide 16S metabarcoding dataset. Across 436 sites belonging to seven contrasting temperate land uses (e.g., arable, grasslands, woodlands, heathland and bog), SRB richness was relatively low across land uses but greatest in grasslands and lowest in woodlands and peat-rich soils. There was a shift in dominant SRB taxa fromDesulfosporosinusandDesulfobulbusin arable and grassland land uses to Desulfobaccain heathland and bog sites. In contrast, richness of other generalist anaerobic bacterial taxa found in our dataset (e.g.,Clostridium,GeobacterandPelobacter) followed a known trend of declining richness linked to land-use productivity. Overall, the richness of SRBs and anaerobes had strong positive correlations with pH and sulphate concentration and strong negative relationships with elevation, soil organic matter, total carbon and carbon-to-nitrogen ratio. It is likely that these results reflect the driving influence of pH and competition for optimal electron acceptors with generalist anaerobic bacteria on SRB richness.
