The potentiality of  Saccharomyces cerevisiae  SRCM 501804 to remove arsenite (As[III]) in an aqueous solution was investigated in this study. The  S. cerevisiae  SRCM 501804 was isolated from Korean turbid rice wine ( Makgeolli ). The  S. cerevisiae  SRCM 501804 was characterized by phylogenetic analysis, Fourier transform infrared (FT-IR) spectroscopy, visual minerals technologies (MINTEQ) model, and point of zero charge (pH pzc ). The relationship between the factors (pH, biosorbent dosage, contact time, and concentration) and biosorption capacity was investigated. The  S. cerevisiae  SRCM 501804 was removed 31.1–90.1% of the As(III) depending on the initial biomass dosage within 1 h. Co-existing anions in aqueous solution showed a negative influence on the biosorption performance of As(III) in the order Cl −  &gt; NO 3−  &gt; SO 42−  &gt; CO 32− . The results of isotherms and kinetics suggested the Langmuir ( R2  &gt; 0.95) and Pseudo-second order ( R2  &gt; 0.99) models fit well with the equilibrium experimental data. The maximum biosorption capacity ( q m) of  S. cerevisiae  SRCM 501804 biomass for As(III) was found to be 113.9 mg/g from Langmuir isotherm. Based on the results, it can be concluded that the biomass of  S. cerevisiae  SRCM 501804 could be used as an effective bio-sorbent for As(III) biosorption in an aqueous solution.
