Yeast Tolerance to Chromium Depends on Extracellular Chromate Reduction and Cr(III) Chelation
The sensitivity of the yeast Pichia guilliermondii ATCC 201911 (L2) to Cr(VI) and Cr(III) has been investigated.This yeast was demonstrated to have much higher resistance to Cr(III), compared to Cr(VI).At chromate level of 2.0 mM, an expanded lag phase in growth was observed, followed by the active phase of cell proliferation.During the growth arre
