Abstract

Resource availability is a key factor regulating biodiversity and ecosystem functioning, but the relationship between resource availability and diversity has only been rarely investigated in microbial communities. The aim of this study was to determine how diversity and community structure of a functional group of soil bacteria are influenced by resource concentration. To achieve this, we used soil microcosms to investigate degradation of benzoate, which served as a model compound, by soil bacterial communities. Microcosms were supplied with (13)C-labelled benzoate at four concentrations and RNA-stable isotope probing followed by molecular fingerprinting analysis of 16S rRNA genes was employed to identify bacteria able to assimilate benzoate at different concentrations. The composition of the benzoate degrader community differed at different concentrations and there was a significant decrease in taxa evenness at the highest substrate concentration. Active organisms could be grouped into generalists, occurring at all substrate concentrations, specialists, active at one particular benzoate concentration only, and taxa that were active at either the two lowest or two highest concentrations. The study comprises the first explicit d...Continue Reading
