Abstract

Living fungal mycelium with suppressed or abolished fruit-forming ability is a self-healing substance particularly valuable biomaterial for further engineering and development in applications such as monitoring/sensing environmental changes and secreting signals. The ability to suppress fungal fruiting is also a useful tool for maintaining stability (e.g., shape, form) of a mycelium-based biomaterial with ease and lower cost. The objective of this present study is to provide a biochemical solution to regulate the fruiting body formation to replace heat killing of mycelium during production. We discovered that GSK-3 activity directly correlates with the development of fruiting bodies in fungi, especially mushroom forming fungi such as Coprinopsis cinerea. By regulating GSK-3 expression and activity, one can control the fungal fruiting body development. We successfully demonstrated that treatment of an inhibitor of GSK-3 kinase activity resulted in acceleration in mycelium growth rate, absence of fruiting body and general decrease in GSK-3 gene expression. Therefore, GSK-3 inhibitor is suggested to be included in the mycelium cultivation recipes for regulating the growth of fungal mycelium and for inhibiting the development of fr...Continue Reading
