- Abstract
The present paper presents the screening of two yeast strains, for the obtainment of forage biomass from grape marc diffusion solution supplemented with wine yeast extract. The yeast strains used were Saccharomyces ellipsoideus originating from alcoholic fermentation, and a strain of Rhodotorula sp. Protein biosynthesis was monitored by determining the following parameters: alcohol concentration at the beginning and end of the process, the optical density of the culture medium, the residual sugar, and the wet and dry biomass. Better results were obtained for Rhodotorula sp. strain, and this can be explained by the presence of glucose which is a much better tolerated carbon source than the ethanol.
