초록

방송이를 4% H$_2$SO$_4$,용액으로 1.5kg/$ extrm{cm}^2$에서 30분간 전가수분해 시키면 원료에 대한 당화율은 21%을 얻었으며 생성된 당화액에 효모 Candida를 배양한 결과 당이용율은 20.5%에 불과하며 생성당에 대한 균체량의 비율은 21.25%을 얻을 수 있었다.

For the purpose of producing single cell protein out of an agricultural waste, chestnut-bur was hydrolyzed with 4% H$_2$SO$_4$, solution for 30 min under the steam pressure of 1.5kg/$\textrm{cm}^2$, and 21% saccharification of the original carbon source was obtained. When Candida tropicalis was grown in the hydrolyzate the cell yield remained only 21% of the original sugar suggesting a necessity of further treatments.
