The Mechanism of Chromium Biosorption by Saccharomyces Cerevisiae
Authors
Abstract:
The Biosorption property of S. cerevisiae for chromium uptake was investigated in an immobilized cell bioreactor. Saw dust was utilized as the solid bed in the reactor. Adsorption of S. cerevisiae on saw dust obeys a first order reaction kinetic up to 6 hours. The immobilized biomass particles are porous and exist in the new generation of biological adsorbent. Chromium biosorption was studied in this bioreactor. The maximum uptake capacity of the heavy metal is a function of the initial chromium concentration. Chromium biosorption obeys a Freundlich isotherm kinetic model.

Cadmium biosorption by Saccharomyces cerevisiae.
Cadmium uptake by nonliving and resting cells of Saccharomyces cerevisiae obtained from aerobic or anaerobic cultures from pure cadmium-bearing solutions was examined. The highest cadmium uptake exceeding 70 mg Cd/g was observed with aerobic baker's yeast biomass from the exponential growth phase. Nearly linear sorption isotherms featured by higher sorbing resting cells together with metal depo...

The microbial dried biomass of Thraustochytrids is used as bioadsorbent for the removal of the chromium in aqueous solution. In this investigation, three species of Thraustochydrids namely Aplanochytrium sp., Thraustochytrium sp. and Schizochytrium sp. were tested for the efficiency of chromium accumulation by culturing in chromium-incorporated medium at 30°C for one week incubation. The biomas...
full textCopper Tolerance and Biosorption of Saccharomyces cerevisiae during Alcoholic Fermentation
At high levels, copper in grape mash can inhibit yeast activity and cause stuck fermentations. Wine yeast has limited tolerance of copper and can reduce copper levels in wine during fermentation. This study aimed to understand copper tolerance of wine yeast and establish the mechanism by which yeast decreases copper in the must during fermentation. Three strains of Saccharomyces cerevisiae (lab...

Hexavalent chromium, a highly toxic metal ion employed in industrial activities, is considered as a first priority pollutant. In this study, the capsule walls of the boll of cotton (cotton waste, CW) and the waste obtained from pruning barberry bushes (barberry waste, BW) were investigated as cheap and locally available adsorbents for Cr (VI) removal. The adsorption behavior, equilibrium, and k...
full textOptimization of Cadmium, Zinc and Copper biosorption in an aqueous solution by Saccharomyces cerevisiae
Optimization of Cd (II), Zn (II) and Cu (II) biosorption from contaminated water were performed as function of parameters (pH, contact time, initial metal ions concentration and yeast dose). The experimental results showed that the highest equilibrium adsorption capacity at the optimum pH were 8.5 for Cd (II) and 6 for Zn (II) and 6 for Cu (II). Optimum pH values were carried out to evaluate ot...
