Abstract

A novel pre-purification method was developed for producing peroxidase to guarantee high purity and yield from plant cell cultures in large-scale process. This method was a simple and efficient procedure for the isolation and pre-purification of peroxidase from the biomass consisting of active clay treatment followed by cationic exchange chromatography. The use of active clay in the pre-purification process allows for rapid and efficient separation of peroxidase from interfering compounds and dramatically increases yield and purity of crude peroxidase for purification steps compared to alternative processes. This pre-purification process serves to minimize the buffer usage size and complexity of the HPLC operations for peroxidase purification. This process is readily scalable to a pilot plant and eventually to a production environment where mass production of material are expected to be produced.

식물세포배양으로부터 peroxidase를 대량 생산하기 위한 분리/정제 공정 으로서 세포를 파쇄하고 크로마토그래피 전처리로서 활성백토를 적용하였다. 활성백토는 미세한 세 포 조각 뿐만 아니라 여려가지 불순불을 선택적으로 흡착 하는 성질을 나타내었으며, 이를 통하여 효과적으로 정제 공정을 진행할 수 있었다 흡착을 통한 전처리 후 한외여 과장치를 이용하여 농축을 실시 하였으며, DEAE-Sepharose F FF를 이용한 크로마토그래피를 통해 정제가 이루어졌다. 활성을 나타내는 용액을 탈염, 농축 후 동결 건조하였다. 이 공정은 상업화에 필요한 대량 정제를 가능하게 하였으며 수율과 정제비용 측면에서 상당히 경제적인 공정임을 입증하였다, 활성백토를 이용한 흡착공정은 다른 효소 및 단백질의 경제적인 대량정제에 적용될 수 있으리라 기대된다.
