초록

효모의 종류에 따라 세포벽의 composition이 다른 것으로 알려져 있으나 이에 대한 체계적인 연구는 아직 이루어지지 않고 있다. 본 연구에서는 한국 유전자은행 (KCTC)과 한국미생물 보존센터 (KCCM)에서 구입한 15종류의 효모를 $Glucanex^{(R)}$ 200G로 처리한 후 생균수를 측정하여 상대적인 저항성을 비교하였다. 그 결과 Trigonopsis variabilis나 Sporidiobolus pararoseus는 $\beta$-glucanase에 대한 저항성이 높았으며 Pichia stiptis나 Filibasidium cpasuligenum은 $\beta$-glucanase에 대한 저항성이 낮았다. $\beta$-glucan의 함량이 높은 세포는 높은 농도의 $\beta$-glucanase 농도에서도 저항성을 가지므로 이를 바탕으로 여러 효모의 세포벽의 상대적인 $\beta$-glucan 함량을 추정할 수 있다.

The cell wall of fifteen yeast strains were treated with Glucanex$^{(R)}$ 200G that contained mainly ${\beta}$1,3-glucanase and some ${\beta}$1,6-glucanase. In our previous study it was found that the yeasts that are more resistant to Glucanex$^{(R)}$ 200G treatment contained more ${\beta}$-glucan than the yeasts that are less resistant to Glucanex$^{(R)}$200G treatment. By measuring the resistance of cell wall to Glucanex$^{(R)}$ 200G, the relative content of ${\beta}$-glucan in yeast cell wall could be estimated. The resistance of cell wall to Glucanex$^{(R)}$ 200G was measured by counting viable cell number after reaction with and without Glucanex$^{(R)}$200G. The resistance of fifteen yeast strains to Glucanex$^{(R)}$ 200G were presented.ere presented.
