Levels of enzymatic activities corresponding to neutral (CpNtc1) and acid (CpAtc1) trehalases in exponential phase cultures of the strain WT and Cpatc1Δ null mutant (KO) submitted to different stress treatments.

The samples were prepared and the enzymatic activities were measured as described in Methods. The results are the mean ± SD of one representative experiment of two performed in triplicate. The distinction between the treated samples and control values obtained was significant at **PaValues are nmol glucose min−1 (mg protein) −1.
