| 摘要 |
The present invention provides a cellobiase produced by Cellulomonas biazotea and nucleic acid molecules encoding such cellobiase enzymes. Recombinant yeast and E.coli which produce the enzyme extracellularly are detailed. In addition, a Sacharomyces cerevisiae strain transformed with genes which encode a cellobiase, an endoglucanase and an exoglucanase is proposed whereby the transformed strain is capable of converting cellulose to glucose and thence to ethanol. |
