It was developed a biotechnological process to reduce chemical oxygen demand (COD) & Biochemical Oxygen Demand (BOD) from industrial waste water, simultaneously, it was evaluated the potential bioconversion of some yeast into Food yeast & ethanol production. It was produced a reduction of the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) of potatoes starchy processing industry from 22,5000 Chemical Oxygen Demand (COD) and Biochemical Oxygen demand (BOD) of COD to 1480 mg O2/ L and 26,400 mg O2/L BOD to 2100 mg O2/ L BOD with an aerobic mixed culture of Candida tropicalis BT-UNSM 124 and LIpomyces sp BT-UNMSM-145. It was produced a reduction of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (DBO) of dairy effluent diluted from 22,100 mg O2/ L COD to 1280 mg O2/ L and 17,500 mg O2 / L BOD to 1100 mg O2/ L of BOD with an aerobic culture of Kluyveromyce...

This work was carried out with the purpose to optimize physical chemical parameters obtain a microbial biomass from Kluyveromyces marxianus NRRL –Y-1109 y Candida pseudotropicalis BT-UNMSM_6 . The yeasts were grown on sweet whey crude and deproteinized, supplemented with nitrogen and vitamins sources. The optimization of fermentation parameters was obtained applying a Taguchi´s factorial design. It was established as optimal conditions: An pH 4.5; Temperature 30 °C and an aeration rate of 1.475 VVM; Agitation speed 600 RPM, Lactose concentration 5 g/L; (NH4)2S04 6 g/L; Yeast extract 1.5 g/L . The average biomass yield obtained was 0.56 g/g lactose and 0.54 g/g Lactose for K. marxianus and C. pseudotropicalis respectively grown on sweet whey deproteinized diluted 50%, and Cellular yield 0.405 g/g with K. marxianus NRRL-Y-1109 and Yx/s 0.38 g/g with Candida pseudotropicalis grown on sw...
