Figure 3From: High yield recombinant penicillin G amidase production and export into the growth medium using Bacillus megateriumComparison of growth media for PGA production and export using B. megaterium. MS941 carrying pRBBm23 (encoding SP pga -PGA) grew in LB (square), A5 (circle), and MOPSO (triangle) medium. The pga expression was induced at OD578nm of 0.4 by adding 5 g L-1 xylose. (A) Solid symbols represent the measured growth curve. (B) open symbols represent specific PGA activity.Back to article page
