Abstract excerpt
A stable mutant flocculent yeast strain of Saccharomyces cerevisiae KRM-1 was isolated during repeated-batch ethanol fermentation using kitchen refuse as the medium. The mechanism of flocculation and interaction with the medium was investigated. According to sugar inhibition assay, it was found that the mutant flocculent strain was a NewFlo phenotype. Flocculation was completely inhibited by protease, proteinase...
