Figure 2: (A) Growth curve (●) and Cr(VI) reduction curve (○) for strain LZ-01 incubated with 0.4 mM Cr(VI) and growth curve (■) and Cr(VI) reduction curve (□) for strain LZ-01 incubated without Cr(VI). (B) Cr(VI) reduction rate calculated from the total Cr(VI) reduced over 120 hours for S. aureus strains LZ-01, LZ-02, LZ-03, LZ- 04. Control was E. coli strain DH5α.
