Abstract excerpt
Two types of trehalase activities different in the optimum reaction pH (4.3 and 6.7) were found in a freeze-tolerant yeast, Torulaspora delbrueckii D2-4, and three types of the activities at pH 4.3, 5.7, and 6.7 were found in its freeze-sensitive mutant (60B3). The pH 4.3 activities in the cell extracts of the two strains were on the same level, but the pH 6.7 activity in the strain D2-4 was about half of that in...
