Strain-specific responses of four salt-tolerant bacterial isolates (ST1, ST2, ST3, and ST4) to the stress induced by high salt concentration at both physiological and biochemical levels shown by the hierarchical graph. The measured parameters represented by damage markers, overall antioxidant capacity, antioxidant metabolites, and antioxidant enzymes are grouped into three main clusters based on their response to high salt stress.
