Abstract excerpt
In order to increase the release of cell wall polysaccharides during alcoholic fermentation, a wine strain of Saccharomyces cerevisiae was subjected to UV mutagenesis to obtain thermosensitive autolytic mutants affected in cell wall integrity. Five mutants and the parental strain were utilized in fermentation trials conducted at 28, 32 and 34 degrees C. Results showed that at all temperatures the mutant strains...
