A biotechnological approach for removing heavy metals from the environment involves the use of biosorbents such as bacteria, yeast, and algae. Heavy metal decontamination in food and water can also be accomplished with these microbes. Using Saccharomyces cerevisiae as a model, our study team looked at heavy metal biosorption in milk. Initial heavy metals (Pb, Cd, and Hg) were introduced to milk, and the bioremoval process was tracked for four days. The goal of this study is to see how exposure duration, temperature, S. cerevisiae concentration, and beginning metal concentration affect the bioremoval process of heavy metals (Pb, Cd, and Hg) in milk. S. cerevisiae concentration, beginning metal concentration, and exposure duration were statistically substantially linked with heavy metals removal (p values 0.05) according to the ANOVA analysis. After 4 days with 30108 CFU S. cerevisiae in milk, the maximum biosorption (70%) was found. These findings added to the growing body of data that S. cerevisiae is an effective biosorbent for heavy metal removal from milk, as well as a potentially safe and environmentally friendly tool for ensuring a safe and healthy food supply.
