Cordyceps militaris: Bioactive Compounds, Cultivation Enhancement and Nanotechnology Applications in Medicinal Mushroom Production

Abstract

Cordyceps militaris has emerged as a valuable medicinal fungus and sustainable alternative to endangered Ophiocordyceps sinensis. This review synthesizes current knowledge on C. militaris taxonomy, bioactive compounds, therapeutic applications, and cultivation technologies. The fungus produces valuable nucleosides, particularly cordycepin and adenosine, exhibiting anticancer, immunomodulatory, and ergogenic effects. Traditional cultivation methods have been enhanced through elicitation strategies including nutrient supplementation and environmental manipulation. Iron supplementation notably increases cordycepin production by 70%, while UV-B exposure enhances multiple bioactive compounds. Recent nanotechnology advances present promising opportunities for biofortification, with metal sulfate nanoparticles showing potential for improving fungal growth and secondary metabolite biosynthesis. However, systematic investigation of nanoparticle applications in C. militaris cultivation remains unexplored. The global cordycepin market value emphasizes the economic importance of efficient production methods. Current cultivation challenges include optimizing defined media for industrial-scale fruiting and developing standardized protocols. This review identifies significant research gaps in nanotechnology applications for medicinal mushroom cultivation and highlights opportunities for sustainable production enhancement to meet increasing global demand while supporting wild species conservation.
