Fig. 5From: Engineering prokaryotic regulator IrrE to enhance stress tolerance in budding yeastEffect of IrrE on the tolerance related metabolites in S. cerevisiae. Intracellular reactive oxygen species (ROS) content (a), the activities of SOD (b) and CAT (c), the intracellular ATP content (d) and trehalose content (e) in S. cerevisiae strains in their middle of the lag phase with or without FAP conditions. Results are the mean of duplicate experiments and error bars indicate s.d. * is for p < 0.05 and **is for p < 0.01Back to article page
