Abstract

Bio-based alternative leathers may be produced from biomass fiber, protein polymers, bacterial cellulose, and mushroom mycelia. Of these components, mushroom mycelia are of greatest interest. In this study, the potential of Fomes fomentariusas a mushroom mycelial mat was confirmed, and the optimal strain for the development of the mycelial mat was determined. Moreover, the quality of the mycelial mat was improved by identifying an efficient culture method to increase productivity. Mutant strains whose independence was verified were obtained by treatment with gamma irradiation under various conditions. Biofilm formation by the resulting strains was examined in sawdust and liquid media and the characteristics of the biofilms were analyzed. The biofilm of the mutant strains showed results that were similar to or better than the biofilms of longevity and cypress mushrooms. These findings are expected to be utilized in future research aimed at discovering new biomaterials using mushroom mycelia.

본 연구에서는 균막 형성을 위해 기존에 활용하고 있는 버섯 종과 다른 말굽버섯을 활용하였으며, 다양한 조건으로 감마선 조사를 진행하여 독립성이 검증된 변이균주를 획득하였다. 확보된 균주들의 톱밥배지 및 액체배지에서의 균막 형성을 관찰하고 각 균막의 특성을 조사한 결과 장수버섯, 시루송편버섯의 균막과 비교하여 비슷하거나 더 좋은 결과를 보인 균주를 확인할 수 있었다. 또한 톱밥배지보다는 액체배지에서 배양 했을 때 균막의 활용도 및 경제성이 더 높은 것으로 판단된다. 본 결과는 버섯 균사체를 이용한 대체육, 바이오소재 발굴을 위한 연구에 활용할 수 있을 것으로 여겨진다.
