Abstract
|
|
|
Various kinds of native herbage grasses like Miscanthus sinensis, Arundinella hirta, Cymbopogen geirngii, Themeda japonica etc. are widely distributed in every Korean mountain.
So we investigated the availability of native grass, Miscanthus sinensis as a substrate for the production of S.CP.
The results were obtained as follows.
1) At the alkali treatment, NaOH was the most effective with the exclusion of lignin, and pretreated Miscanthus with NaOH appeared to be a good substrate for the microbial growth.
2) When Miscanthus was treated with one to 10% NaOH, the microbial growth increased in proportion to the increased alkali concentration. Beyond 4% NaOH, a slight increase was observed.
3) Phosphoric acid, as a neutralizer, was the most effective in cell production after alkali treatment.
4) On the effect of incubation time, the productivity was best found at 60 hours, and the cell weight was 9.23 mg per 1 ml, and the microbial digestibility of substrate was 75.2 %.
