Abstract

Fermentations with mixed cultures of the cellulolytic fungus Trichoderma viride and the yeast Saccharomyces cerevisiae or __Candida utilis__were examined. The fermentations were carried out in an aerated 5 liter fermentor with NaOH treated barley straw as the cellulose source (2–4%). Yeast was inoculated 24–32 hr after the fungus and the growth of the two organisms was followed through the production of CO~2~ and cell protein. In comparison with fermentations with __T. viride__alone, the production time for maximum yields of cellulases and cell protein was reduced by several days, depending on the straw concentrations. The protein content of the growth product was 21–22% and the amino acid composition of the product resembled that of T. viride alone.
