Comparison 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 OD_578nm 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.
