Microbially produced, physiologically - tolerable, permeable film consisting of chitosan - containing cellulose

摘要

Disclosed is a microbially produced, physiologically - tolerable, permeable film consisting of chitosan - containing cellulose, the essentially with the aid of a cellulose - and chitin producing microorganism was produced and the at least 0,1 w -% chitosan contains. For the production of this equally gas - and / or liquid - and / or transparent film, which, in particular, as a wound dressing and / or a skin replacement and / or as an artificial blood vessels is used, are in particular recombinant bacterial cells of the genus acetobacter xylinum, in which a gene coding for chitin - synthetase with the aid of a plasmid and / or vectors has been transformed. The gene itself should be made from a fungus, such as, for example, aspergillus nidulans or neurospora crassa, originate. The employed host microorganisms can, however, also in addition to the synthesis of with chitin structurally related biopolymers be suitable.
