Abstract

Trichoderma spp. are very important as being a major source for the industrial production of various secreting enzymes in the field of white biotechnology. In this work, Agrobacterium-mediated transformation (AMT) was studied using Trichoderma sp. KACC 40541 which has high activities of amylase, pectinase, cellobiohydrolase and xylanase. In principal, optimized NaOH treatment, prior to Agrobacterium infection, to the mycelium was determined to be very effective for AMT.

Trichoderma spp.는 white biotechnology에서 이용되는 대표적인 미생물로서 이들이 강력하게 분비 생산하는 효소들은 산업적으로 매우 중요하다. 본 연구에서는 amylase, pectinase, cellobiohydrolase 및 xylanase 분비활성이 높은 것으로 밝혀진 Trichoderma sp. KACC 40541균주에 대한 Agrobacterium이용 형질전환을 수행하였으며 균주개량을 위한 효율적인 유전자도입 방법을 제시하였다. 특히 형질전환을 위하여서는 균사체에 대한 적정 농도의 NaOH처리가 매우 효과적임을 보여주었다.
