Abstract:   (83 Views)
Background: Bioavailability is a good alternative to conventional physical and chemical methods for removing toxic metals from groundwater and wastewater.
Methods:  In this research, phenotypic and genotypic study was carried out on the use of isolated yeast from industrial effluents with the aim of eliminating Selenium biological and the production of biomass as a feed for livestock and poultry. In the present study, yeast strains were isolated from wastewater and after confirmation by using the replication of the ITs region and their evolutional correlation with S1 strains (Candida albicans NG67) and S2 (Candida albicans m48a) selenium removal was performed.
Results:  The ability of these isolates to tolerate selenium was performed using PYT agar medium containing different concentrations of 4-15 mM of Se2 +. Selenium-capable strains of reddish colonies contained Selenite in PYD Agar medium. These strains were selected as superior strains.
Conclusion: The MFC test was conducted to select the best yeast strain for performing desulphurisation tests. The resistance pattern of isolated yeast strains according to MFC showed that the highest resistance to toxic selenite ions (tolerance greater than 22 g / l) was related to strain S1. The microbial protein produced in this study is widely used and can be used as an additive and probiotic in the diet of livestock, poultry, and aquatic animals.
