Bioleaching can be considering a simple and effective technology for removing metals from waste which is rich in heavy metals. Bioleaching of these metals by microorganisms offers an economical and eco-friendly approach. In this study Saccharomyces cerevisiae NCYC2592, was used to remove metals from municipal solid waste (MSW). The tolerance of S. cerevisiae against the metals was determined using phenotypic microarrays using artificial hydrolysate containing various metals. Parameters such as one and two way methods or process, yeast strains, pH and mediums were studied and optimized. The results revealed that two-way methods and S. stipitis strain among five strains, using artificial media correlated with better performance at pH 5.5, while at pH 4 Correlated with sorghum media which showed lowest retained yield %.
