The conversion of crude sweet whey to single cell protein by a mixed culture of the yeastsCandida kefyr LY496 andCandida valida LY497 in non aseptic conditions was investigated. In comparison with single “pure culture” ofCandida kefyr LY496, ethanol accumulation during batch was prevented using the mixed culture. The efficiency of whey conversion to biomass was thus increased by as much as 20%.
