Abstract / Bemerkung
In order to improve the effectiveness of the production of recombinant proteins in E. coli, integrated fermentation processes were developed. Therefore, expression vectors were constructed containing a strongly expressed gene for a beta-glucanase fused with a metal-chelating affinity tag and a leader peptide for directing the fusion protein into the periplasmic space. Its export into the medium was achieved by means of co-expression of a bacteriocin-release protein, the Kil protein from pColE1. Bioreactors were modified so that special devices containing metal chelate pentadentate chelator PDC resins were located within the bioreactor. Using the bioreactor with an internal device the Zn2+-PDC had a 4.3-fold higher binding capacity than metal-free PDC (12.3 and 2.6 kU ml(-1) PDC, respectively. Using the bioreactor with charged PDC in an external circuit revealed even higher beta-glucanase concentration (65.6 kU ml(-1)), i.e. 1.5-fold compared to the internal adsorbent system.
