CAT activity is expressed as nmol of chloramphenicol acetylated mg of protein−1 min−1, followed by the standard deviation in parentheses. The data are averages from at least three independent cultures, and all assays were performed in triplicate. The carbohydrate concentration in the growth medium was 0.5% (wt/vol). Glc, glucose; Fru, fructose; Gal, galactose.
