Studies on the Feed Stuffs from the Agricultural Waste Part II Conditions of post-hydrolysis from chestnut-bur and yeast production from post-hydrolyzate.

농생폐자원의 사료화에 대한 연구 제이보 밤송이의 후가수분해의 조건과 후가수분해액에 대한 효모생대

The pre-hydrolyzed residue of Chestnut-bur (1) was treated with 74％ H$_2$SO$_4$, solution at 3$0^{\circ}C$ for 40minutes. Then the solution was diluted to 5％ with distilled water and kept for another 40 minutes under steam pressure of 1.5kg/㎤ to complete the post-hydrolzation. In the resulting hydrolyzate, which showed 49.3％ in saccharification rate, Candida utilis was grown and found that 62.5％ of the reducing sugar had been converted to the yeast cells.

전가수분해가 끝난 밤송이에 74% H$_2$SO$_4$로 일차가수분해 시킨 후 1.5kg/㎤의 증기압하에서 40분간 가수분해 시킨 결과 원료에 대해서 49.3%의 당화율을 얻었으며 여기에 Candida utilis를 배양한 결과 당이용율은 60%이며 생성된 중량은 환원당의 62.47%이었다.
