Abstract
In our earlier paper, authors have been reported that Ni(II) resistant Saccharomyces cerevisiae AJ208 was developed to remove the elevated level of Ni(II) concentration, and 70% removal was observed concerning the initial Ni(II) concentration of 3000 mg/L. This article aims to screen the facilitated Ni(II) removal after optimizing carbon-nitrogen and macro-micro elements as nutritional supplements into fermentation media from an aqueous solution. In the fermentation media, the synthetic carbon-nitrogen sources and macro-micro elements were added and optimized to obtain better Ni(II) percentage removal from the aqueous solution by using the Ni(II) resistant strain of S. cerevisiae AJ208. As newly optimized carbon-nitrogen sources, sucrose, and ammonium chloride collectively provide 75% Ni(II) removal. The macro-micro elements, magnesium sulfate, potassium dihydrogen phosphate, potassium chloride, calcium chloride, ferric sulfate, and zinc sulfate, positively impacted S. cerevisiae AJ208 growth and fermentation. After optimization, it provided 85% Ni(II) removal. The adsorbent was also characterized with SEM-EDAX, Raman, and FTIR analysis. The adsorption study shows a striking enhancement in Ni(II) removal after adding mentioned nutritive elements. The genetic algorithm is also successfully applied using the data acquired from the experiment.
