  • SummaryA new series of maltase negative mutants have been isolated from yeast strains carrying the MAL4 gene. These mutants are allelic to the MAL4 gene and fail to ferment maltose, sucrose, and alphamethylglucoside. Most revertants isolated from these mutants restore the ability to ferment above sugars, and also produce the same levels of maltase as the parental strains. One of the revertants (NA-520-R1), however, ferments maltose slowly, and produces 24 fold less enzyme than the parental… CONTINUE READING
