Ca. Biekeibacterium resiliens” appears to be a chemolithoautotrophic bacterial population capable of carbon fixation and can probably oxidize thiosulfate to sulfate via the SOX complex. The presence of SOX complex also indicates that oxygen is the preferred electron acceptor, but if there are oxygen limitations, nitrate, iron or organic matter could be used instead as alternative electron acceptors based on hallmark genes identified in the genome for these pathways (Kuever, Rainey & Widdel, 2005). “Ca. Biekeibacterium resiliens” suggests to be (1) capable of glycolysis and carbon fixation, (2) potential for thiosulfate oxidation through the SOX complex, (3) non-nitrogen fixer, (4) non-photosynthetic. “Ca. Biekeibacterium resiliens” appears to be capable of thiosulfate oxidation (100% pathway completeness), nitrate/nitrate transport (100% completeness), NarX-NarL two component regulatory system (100% completeness), cytochrome c oxidase for ATP synthesis (100% completeness), assimilatory nitrate reduction (50% completeness), dissimilatory nitrate reduction (50% completeness). In addition, potential for carrying a xenobiotic reductase B (XenB) and oxygen nitroreductase (nfsB), which indicate capacity for biodegradation of explosives, and copper export (copA). The latter suggests that “Ca. Biekeibacterium resiliens” is a genetically and phenotypically versatile bacterium that is enriched after exposure to organic pollutants such as explosives.
The type genome BioSample is SAMN16502674 but no genome accession is given in Dávila Santiago et al 2021.
