Abstract

Shiitake breeding requires the procedures of mating of two different parental strains and selection of hybrid strains that have good traits for the mushroom production. In this study, we tested the possibility of the use of chromogenic plate-based assay for extracellular enzyme production in order to assess and find good biochemical properties-possessed hybrid strains that were generated from genetic cross of the monokaryotic strains derived from two different parental strains of Lentinula edodes Sanjo-101ho and Sanjo-108ho. We observed that there was difference in the ability of producing ${\beta}$-glucosidase, avicelase, CM-cellulase, amylase, pectinase, xylanase, and protease among the monokaryotic strains. We could also comparatively assess that the ability of the seven extracellular enzymes production in the hybrid strains depended on the mating combination of the monokaryotic strains. Our results demonstrate that the assessment method for extracellular enzyme production using chromogenic plate assay could be usefully applied to the assessment of the hybrid strains derived from the breeding procedure of L. edodes.

표고버섯의 육종은 두 개의 다른 모균주에 의한 교배와 버섯생산에 좋은 형질을 지닌 교잡균주의 선발이 요구된다. 본 연구에서는 서로 다른 두 계통의 표고 모균주에서 유래한 단핵균주와 이들 단핵균주간의 교배로부터 만들어진 교잡균주에 대하여 발색반응 배지를 이용하여 세포외 분해효소의 분비능력 정도를 비교하여 생화학적 특성이 우수한 균주를 선발할 가능성에 대하여 조사하였다. 모균주로부터 유래한 단핵균주들 간에 ${\beta}$-glucosidase, avicelase, CM-cellulase, amylase, pectinase, xylanase, protease의 분비능력에 차이가 있음을 확인하였다. 교잡균주에 있어서도 단핵균주의 조합에 따라 효소 분비능력이 달라지는 것을 볼 수 있었다. 이에 따라 발색반응배지를 이용한 세포외효소 평가법이 표고의 육종과정 중에 생성되는 교잡균주들의 평가에 활용 할 수 있을 것으로 사료된다.
