Fig. 4From: High-level production of γ-cyclodextrin glycosyltransferase in recombinant Escherichia coli BL21 (DE3): culture medium optimization, enzymatic properties characterization, and product specificity analysisThe product specificity analysis of γ-CGTase. The concentrations of α-, β-, and γ-CD in the products of a non-solvent group, b the standard substance, and c the cyclododecanone group were determined by HPLC. d The purity and e the yield of γ-CD was calculated according to the result of HPLC. The data were presented from three independent experimentsBack to article page
