sulfur-based autotrophic bioreduction of Cr(VI) mediated by inorganic carbon species: microbial community
we established a Cr(VI)-SAR system interfaced with diverse IC species, providing definitive insights into electron transfer mechanisms through rigorous multi-biocycle analysis and thermodynamically consistent half-reaction calculations. Through quantification of electron transfer pathways, we derived reaction equations for Cr(VI) reduction in conjunction with various IC species.
