The ΔpbsB mutants were more sensitive to hyperosmotic stress. (A) The colonies of WT, ΔpbsB mutant and OE strain in YES medium with or without 1.2 mol/L Sorbitol. (B) Inhibition rate of growth with 1.2 mol/L Sorbitol. The inhibition rate = (diameter of colony without inhibitor—diameter of colony with inhibitor)/diameter of colony without inhibitor.
