Biogeochemical cyclic activity of bacterial arsB in arsenic-contaminated mines
Keywords: arsenic resistance bacteria,arsB influx/efflux pump,arsenic resistance system (ars) biogeochemical Abstract: Biogeochemical cyclic activity of the ars (arsenic resistance system) operon is arsB influx/effux encoded by the ecological of Pseudomonas putida.This suggests that studying arsenite-oxidizing bacteria may lead to a better understanding of molecular geomicrobiology,which can be applied to the bioremediation of arsenic-contaminated mines.This is the first report in which multiple arsB-binding mechanisms have been used on indigenous bacteria.In ArsB (strains OS-5; ABB83931; OS-19; ABB04282 and RW-28; ABB88574...
