ABSTRACT OF THE DISCLOSURE The invention relates to a process for the preparation of fodder yeast and/or ethanol from plants or cellulose-containing wastes of plant origin. Accor- ding to the invention the cellulose-containing starting substance is pre-treated with a dilute mineral acid and/or a dilute base, and then fermented under aerobic or anaerobic conditions in the presence of a Candide utilis var. cellulolytica strain deposited at the Hungarian National Collection of Microorganism of the National Institute for Public Health on 23rd September, 1980 under No. CU 28 00199. When fermentation is performed under aerobic conditions, fodder yeast or a mixture of fodder yeast and ethanol is obtained, depending on the aeration rate, whereas when fermentation is performed under anaerobic conditions, ethanol is obtained. By use of a yeast strain which is both suitable for animal fodder and capable of decomposing hydrated and partially degraded cellulose, the process provides a way of producing animal fodder directly from cellulose.
