| Abstract | The adhesion of microorganisms to surfaces and the affecting factors is important in biomining pretreatment. In this research, the novelty is focused on studying the monosaccharide's impact on the adaptability and adhesivity of Ferroplasma acidiphilum for oxidization of sulfide-bearing ore containing pyrite harboring 98% of gold in its crystal lattice. d-sucrose increased EPS production with the highest amount of pyrite dissolution (69%) as compared to the other types of monosaccharides (d-galactose and d-fructose). Addition of 0.8 wt% d-sucrose enhanced the production of ferric ions 65% for the ore load of 20 wt% while for the addition of 0.4 wt%, the ferric ions concentration was maximum up to 95%. The results indicated that the addition of both yeast extract and d-sucrose with the concentration of 0.4 wt% enhanced the EPS (Extracellular Polymeric Substances) biovolume fraction from 7.5 to 32.5 v/v%. |
