There is described a process for the preparation of cellulose film, comprising the steps of preparing a culture medium having as nutrients sources of nitrogen and of carbohydrate, seeding this medium with a culture of acetobacter, species Xylinum; incubating the culture at temperatures which permit bacterial activity for a time suitable to the final intended use of the film, and removing the formed film from the culture medium for dehydration in a distended state. The film thus prepared is suitable for use as an artificial skin graft, a separating membrane, or artificial leather. |
