报告摘要

Two types of extremophiles were utilized in bioelectrochemical systems and omics techniques were used to study substrate utilization and extracellular electron transfer (EET).In an acidophilic MFCs study for tetrathionate (S4O62-) degradation, a combined metagenomic & metatranscriptomic approach revealed the presence of FerroplasmaAcidithiobacillusSulfobacillus, and Cuniculiplasma. This microbial community was suggested to metabolize inorganic sulfur compounds via multiple pathways, and transfer the electrons released from oxidation to the electrode via soluble electron shuttles. The Ferroplasma-like population in this study was the most active1. Metatranscriptomic investigation of a psychrophilic MFC study for thiocyanate (SCN-) degradation suggested that Thiobacillus was the predominant and most active population. mRNA analysis revealed that thiocyanate was metabolized primarily via the ‘cyanate’ degradation pathway; and the resultant sulfide was oxidized with electrons being transferred via the secretion of electron shuttles2.

These findings highlighted the phylogenetic and metabolic diversity of electrochemically-active microorganisms and urged further research to elucidate the genetic basis for EET.
