FIG. 2.

(A) Growth curves for wild-type and Klzwf1Δ mutant strains. Cultures were grown in YP medium containing 1% glucose, and cell density (A₆₀₀) was determined at time intervals. (B) Glucose and ethanol determinations. The concentrations of glucose (D) and ethanol (E) in culture supernatants were determined at the indicated time intervals. wt, wild type; Δ, Klzwf1Δ strain. Each value in the figures represents the average of three independent determinations. In no case was the variation higher than 15%.
