| 摘要 |
The present invention concerns micro-organisms which present cellulases on their surface. Corresponding micro-organisms were produced with the aid of corresponding plasmids which encode a section comprising a signal peptide, a heterologous cellulase, an optional protease recognition site, a transmembrane linker and a transporter domain of an autotransporter or a variant thereof. Such micro-organisms were advantageously used in the conversion of cellulose into cellobiose and/or glucose. It was also possible to recover the micro-organisms from the reaction mixture following conversion from simple substrates. Also, a combination of various micro-organisms, which were populated with exocellulases, endocellulases and beta-glucosidases, were used to produce glucose from cellulose or wood. |
