Qualitative analysis of colony hydrophobicity and pigmentation. The deletion mutant K09 and truncated mutant T10 showed loss of surface hydrophobicity as the dye percolated into the colony within 5 min whereas in wild-type and complementation mutant it was retained as droplet on the surface (a). Reduced pigmentation was observed in K09 and T10 mutants extracted in both ethyl acetate (b) and chloroform (c)
