FIG. 1.

(A) BDH activity staining of parental B. subtilis strains WN1038 (wt), WN1063 (yycR::cat), and WN1075 (ydjL::cat). Colonies were prestained with DCPIP and photographed at 3 min after incubation with 2,3-butanediol. (B) Silica gel TLC of 2,3-butanediol markers (BD, black arrows) and 30 μl of culture supernatants from the following B. subtilis strains: WN1038 (wt), WN1063 (yycR::cat), and WN1075 (ydjL::cat). The dark band at the top of the figure is the solvent front. The dashed line denotes the origin (ori).
