Selection and Community Analysis of Halophiles Mixed Exoelectrogens from Salt Lake Soils

Abstract

In this study, two different slight halophiles mixed exoelectrogens were enriched and selected from salt lake soils. The results showed that the selected mixed exoelectrogens ESA from sample of OSA (Xiaochaidan Lake soil) and ESB from sample of OSB (Dachaidan Lake soil) without additional NaCl produced current density of 1231.1 and 1050.2 μA cm-2, which were 89.6% and 61.7% higher than that typical exoelectrogens G. sulfurreducens PCA, respectively. ESA and ESB could produce 2.7 and 1.9 times currents as high as using G. sulfurreducens PCA with additional 1.5% NaCl, respectively. The community diversity data demonstrated that Proteobacteria was the most abundant phylum, and in which Enterobacteriaceae and Rhodocyclaceae were the domination families for both ESA and ESB. Furthermore, at the genus level, the dominant genera Propionivibrio and Escherichia-Shigella were also shared by them. ESA had higher species diversity when compared with ESB.
