Summary

Temperature-sensitive mutants affecting maltose utilization in the yeast Saccharomyces cerevisiae have been isolated. Two such mutants although failing to ferment maltose at the restrictive temperature, have normal induced level of maltase. The third mutant (UNT-37) not only failed to ferment maltose but has 5–6 fold less induced level of maltase at the restrictive temperature than the parental strain The genetic control mechanisms of maltase induction and maltose utilization have been discussed.
