Growth and chemosensory behavior of sulfate-reducing bacteria in oxygen-sulfide gradients.

abstract：:Biological soil crusts (biocrusts) are common to drylands worldwide. We employed replicated, spatially nested sampling and 16S rRNA gene sequencing to describe the soil microbial communities in three soils derived from different parent material (sandstone, shale, and gypsum). For each soil type, two depths (biocrusts,...
