Xylanase production under control of the pstS promoter. A) Coomassie-Blue-R-stained SDS-PAGE showing the production of the Xys1 xylanase in supernatants of the S. lividans TK24 (wild-type) transformed with different plasmids: pNX30, the xylanase gene has no promoter; pNUF5, the xylanase gene is under the control of the full length pstS promoter; pNUF13, the xylanase is under the 186-bp-deleted pstS promoter (from -329 to -144). 5 μl of culture supernatant was loaded per track. B) Histogram showing the xylanase activity detected in the supernatant of the indicated strains. G, glucose; F, fructose. The results presented are means of three independent experiments.
