Determination of promoter strengths in Clostridium sp. AWRP. (A) Comparison of the strengths of different promoters in Clostridium sp. AWRP. The crude extract of wild-type AWRP did not show background β-galactosidase activities and is not shown. The value of Pxyl was obtained without supplementation with xylose. (B) Strengths of Pxyl with various concentrations of xylose. Shown are representative of three replicates
