Article Synopsis
- Two indigenous yeast strains, Cyberlindnera jadinii M9 and Wickerhamomyces anomalus M10, show potential for detoxifying chromium from textile-dye wastewater through biological processes.
- The study utilized proteomic analysis to identify 39 proteins that increased in production when exposed to hexavalent chromium (Cr(VI)), indicating their role in stress response, metabolism, and energy production.
- Notably, specific enzymes such as nitroreductase and flavoprotein in W. anomalus M10 and reductase enzymes in Cy. jadinii M9 were linked to chromium reduction, marking a new understanding of enzymatic responses to chromium in these yeasts.
The purpose of this study was to investigate the influence of increasing sulfate concentrations on chromium removal, to evaluate the effect of the presence of Cr(VI) on sulfate removal by Streptomyces sp. MC1 and to analyze the differential protein expression profile in the presence of this metal for the identification of proteins repressed or overexpressed. In the presence of Cr(VI) but in the absence of sulfate ions, bacterial growth was negligible, showing the Cr(VI) toxicity for this bacterium.
