Kinetics of beta-glucosidase production by Escherichia coli recombinants harboring heterologous bgl genes
Maximum productivities of beta-glucosidase by E. coli recombinants, under the control of either lacZ or GALI promoters, were 33 +/- 10 and 100 +/- 5 IU l(-1) h(-1), respectively. GALI promoter of pYES2 enabled the E. coli recombinants to produce 3.1- and 15.1-fold more beta-glucosidase than that supported by lacZ promoter of pUC 18 in E. coli recombinants and donor, respectively.
