Abstract

Experiments were carried out to find possibility of economic production of SCP in mixed culture by Cellulomonas sp. KL-6 and E. coli LI-10. The best cell growth was obtained at the ratio of 1 : 1(v/v) in mixed culture. When these strains were mixed culture, cell growth was increased to about 63%, compared with those of single culture of strain KL-6. It was found that the majority of the population during growth in mixed culture consisted of strain KL-6. CaCO₄ added to the medium as the ratio of 0.1% was enhanced medium pH. Cell growth increased in that circumstances. These strains produced much amounts of cellobiose, but glucose was not detected in filter paper medium. When these organisms were cultured under the optimal medium for 4 days, cell mass was produced 1.0 g/ℓ. The results showed the increase of cell mass up to 53% than those produced in CMC medium.
