  • 초록

    표고버섯(Lentinula edodes)의 동위효소 양상을 표고 연구의 기초 연구의 일환으로 실시하였다. 균사체의 Tris-HCl 완충액에 용해되는 세포내 효소를 nondenaturing polyacrylamide gel 전기영동 법으로 분리후, peroxidase, esterase, superoxide dismutase, acid phosphatase, alkaline phosphatase, alcohol dehydrogenase, ${\alpha}-amylase$ 효소 활성을 측정하였다. 표고는 peroxidase, esterase, superoxide dismutase, acid phosphatase 활성이 검출되었으며, 본 연구에서 사용한 방법으로 alkaline phosphatase, alcohol dehydrogenase, ${\alpha}-amylase$ 효소 활성은 검출되지 않았다. 표고버섯의 peroxidase, esterase band는 배양 기간에 따라 큰 차이가 없이 안정하였으며, 동위효소는 표고의 유전적 연구 및 원형질체 융합 후 융합체의 특성 연구에 중요하다.


    The Isozyme activities of Lentinula edodes were studied as a preliminary study for genetic analysis after protoplast fusion. The presence of peroxidase, esterase, superoxide dismutase, acid phosphatase, alkaline phosphatase, alcohol dehydrogenase and ${\alpha}-amylase$ was examined. An intracellular buffer-soluble protein from the mycelia was used for enzyme analysis on nondenaturing polyacrylamide gels. The auxotrophs of Lentinula edodes were positive for peroxidase, esterase, superoxide dismutase and acid phosphatase. However, alkaline phosphatase, alcohol dehydrogenase and ${\alpha}-amylase$ were not detected. The esterase and peroxidase were not affected by the various culture age. Isozyme identification may be a useful tool after protoplast fusion.
