Abstract
A high grade cellulose film is made by causing the organism Acetobacter Xylinum to act on a nutrient bath maintained in a vibration free condition in a sterile atmosphere, and the film is withdrawn continuously or intermittently, steeped in caustic soda, p washed, dried, and reeled. A suitable nutrient consists of glucose 3-5 per cent, alcohol 2 per cent, yeast extract 0.5 per cent, and glacial acetic acid 0.25 per cent. The preferred temperature is about 30 DEG C. and the film takes from 1 to 7 days to grow, according to the thickness required. The drawings (not shown) illustrate a suitable apparatus for growing and treating the film. The film produced is thin, strong and uniform, and may be used for the manufacture of small electric condensers.ALSO:The organism Acetobacter Xylinum is caused to act on a nutrient bath maintained in a vibration free condition in a sterile atmosphere, and the film of cellulose which forms on the surface is withdrawn continuously or intermittently. A suitable nutrient consists of glucose 3-5 per cent. alcohol 2 per cent., yeast extract 0.5 per cent., and glacial acetic acid 0.25 per cent. The preferred temperature is 30 DEG C. and the film takes from 1 to 7 days to grow, according to the thickness required.
