The ACC-deaminase activity and efficiency of ACC-deaminase synthesis of Trichoderma DEMTkZ3A0 cultures after 5 days of incubation at 12 °C (A,B,C), 20 °C (D,E,F) and 28 °C (G,H,I). Results are represented as nMol of α-ketobutyrate/h/mL (ACC-deaminase activity) and as nMol of α-ketobutyrate/g mycelium d.w. or nMol of α-ketobutyrate/h/mg protein (efficiency of ACC-deaminase synthesis). Bars represented standard deviations (SD). Values followed by different letters are significantly different (one-way analysis of variance (ANOVA) followed by a Tukey’s post hoc test with the significance evaluated at p < 0.05).
