Figure 6: TEM micrographs of LZ-01 cells growing with 1 mM Cr(VI) (A) and without Cr(VI) (B) and E. coli strain DH5α growing with 1 mM Cr(VI) (C) and without Cr(VI) (D). The EDX results show the presence of Cr in strain LZ-01 both inside and outside of cells, while Cr was not seen in other preparations.
