Fig. 5From: Development of a strictly regulated xylose-induced expression system in StreptomycesChitobiase activity of a S. lividans XC, b S. lividans XCBR, c S. lividans XCr, and d S. lividans XCPR after 48, 72, and 96 h cultivation. After 48 h, carbon sources (glycerol, d-glucose, d-xylose, d-galactose, and d-fructose) were added to a final concentration of 1.0%, and cultivation was continued for 24 and 48 h (72 and 96 h total)Back to article page
