Notes:
Abstract A lipid hydroperoxide-resistant mutant was isolated from a strain ofSaccharomyces cerevisiae. The mutant was resistant to 1.5mm tert-butylhydroperoxide and 1.0mm linoleic acid hydroperoxide. It flocculated in a Ca2+-dependent manner and the resistance against lipid hydroperoxide was suppressed by mannose, which also inhibited flocculation. A positive relationship between the acquirement of, the flocculent phenotype and resistance against lipid hydroperoxide is suggested. A protein with a molecular weight of 33 kDa was found on the surface of the mutant cell.
