摘要：
The maximum productivity of β-glucosidase by Saccharomyces cerevisiaerecombinants under the control of GALI promoter was 100 IU l−1 h−1. The highest productivity of β-glucosidase by a S. cerevisiae recombinant was 16-fold more than that supported by Cellulomonas biazotea. The recombinants also co-produced ethanol from cellobiose: maximum product yield and productivity were 0.5 and 1.1 g ethanol g−1 cellobiose and g ethanol l−1 h−1, respectively.
