한외여과막을 이용한 단백질 정련액으로부터 단백질 분리

국문 초록 (Abstract)

실크 생산공정 중 발생하는 부산물인 세리신을 회수하기 위하여 제조된 폴리에테르술폰 중공사 한외여과 모듈을 운전하였다. 부산물에 함유되어 있는 비누를 염화칼슘을 이용하여 침진시킨 후 침전된 비누가 함유된 세리신 용액의 침지형 및 가압형 모듈 운전 시 막오염 거동을 살펴보았다. 또한 가압형 모듈 운전 시 비누와 단백질이 막오염에 미치는 영향을 조사하였다. 비누를 제거함으로써 막오염이 줄어드는 경향을 보였다. 이로부터 비누가 침전될 때와 침전되기 전에 단백질 상호간에 영향을 끼치며 분리막에도 영향을 미침을 보여주고 있다.

To recover sericin protein from by-product in silk production process, a polyethersulfone hollow fiber ultra-filtration membrane module was used. The soap in the degummed solution was precipitated by calcium chloride. The influence of membrane module of submerged and external type on membrane fouling was investigated. The effect of soap and protein on the membrane fouling in the external type membrane module was also studied. The removal of soap resulted in decreasing the membrane fouling. It was shown that the protein and the membrane were affected by the soap.
