Abstract
|
|
|
Experiments were carried out to pursue the availability and the feasibility of utilizable cellulosic materials as substrate for the production of cellulosic single cell protein. The resuluts were obtained as follows.
1. Effects of carbolydrates as a sole carbon source on the growth of Cellulomonas flavigena KIST 321 were examined. The result showed that cellulose and xylose would be most utlizable for cell mass production.
2. Alkaline treated waste papers and clothes resulted in good growth of the organism than intact ones did. However the waste papers as substrate of cellulosic fermentation were not digestible, even if the meterial was treated with alkalies.
3. Rice straw, rape straw and panic grass appeared to be good substrates for the cell mass production.
4. Leases were proved to be a good substrate for the cell mass production, but wood sawdust was hardly digested by merely alkaline treatment.
5. When cellulosic wastes as the substrate were examined into the concentration of alkaline solution, the result suggested that the best productivity of cell mass from cellulosic materials was obtained on treatment with 0.8∼1.0% NaOH solution.
6. The productivity of cell mass was increased by washing out with water after alkaline treatment of newspaper, pine sawdust, lime sawust and pine leaf.
