Abstract
|
|
|
1. Penicillium sp. C 13-13 strain was obtained with the treatment of mutagenic agents(N.T.G.) and by single spore isolation method from the Penicillium sp. C8-14 strain, which was reported in the previous paper.
2. The above strain had a few spores and to obtain seed culture, it was cultured at 30℃ and initial pH 4.5∼5.0, with air rate 6ℓ/min., and agitation 600 rpm for 48 hours in 10% wheat bran medium in 20ℓ- Jar fermenter.
When the broth that had above 70㎖ of mycelium was inoculated into wheat bran medium and incubated at 29∼33℃ for 72 hrs, the cellulase activity of the koji was higher.
3. Adding calcium chloride and magnesium sulfate to the wheat bran medium to 1.5% and 0.015% respectively, the cellulase activity of the koji was higher than that of the control.
