Enhanced microbial reduction of aqueous hexavalent chromium by Shewanella oneidensis MR-1 with biochar as electron shuttle
文献摘要：
Biochar,carbonaceous material produced from biomass pyrolysis,has been demonstrated to have electron transfer property (associated with redox active groups and multi con-densed aromatic moiety),and to be also involved in biogeochemical redox reactions.In this study,the enhanced removal of Cr(Ⅵ) by Shewanella oneidensis MR-1(MR-1) in the presence of biochars with different pyrolysis temperatures (300 to 800 ℃) was investigated to under-stand how biochar interacts with Cr(Ⅵ) reducing bacteria under anaerobic condition.The promotion effects of biochar (as high as 1.07～1.47 fold) were discovered in this process,of which the synergistic effect of BMBC700(ball milled biochar) and BMBC800 with MR-1 was noticeable,in contrast,the synergistic effect of BMBCs (300-600 ℃) with MR-1 was not rec-ognized.The more enhanced removal effect was observed with the increase of BMBC dosage for BMBC700+MR-1 group.The conductivity and conjugated O-containing functional groups of BMBC700 particles themselves has been proposed to become a dominant factor for the synergistic action with this strain.And,the smallest negative Zeta potential of BMBC700 and BMBC800 is thought to favor decreasing the distance from microbe than other BMBCs.The results are expected to provide some technical considerations and scientific insight for the optimization of bioreduction by useful microbes combining with biochar composites to be newly developed.
