B. megaterium YYBm1 is deficient in xylose utilization. Shaking flask cultivation of B. megaterium strain MS941 (ΔnprM) (■), YYBm1 (ΔnprM, ΔxylA) (□), WH320 (▲), and WH323 (ΔxylA) (△) in minimal medium with glucose as initial carbon source. At the beginning of the stationary phase 5 g L^-1 xylose was added as second carbon source into the growth medium (indicated by arrow).
