Filtration Effect of Cordyceps cicadae Mycoderm on Bacteria and its Transport Function on Nitrogen

Cordyceps cicadae, one kind of entomogenous fungus, which has a long medicinal history in traditional Chinese medicine. In this study, we aimed to explore the role of C. cicadae mycoderm. Our results showed that C. cicadae mycoderm has a certain ability to transfer nitrogen, which can transfer nitrogen from the insect body to the external environment, and also transfer nitrogen from the environment to C. cicadae. By studying the filtration of bacterial mycoderm, it was found that the mycoderm of C. cicadae is able to filter out most of the bacteria in the environment. Using the high-throughput sequencing methods, we found that the abundance of bacterial community increased first and then decreased during the growth and development of C. cicadae. The bacterial richness and diversity of mycoderm of C. cicadae cultivated in sterile glass bottles were significantly lower than those cultivated in soil mulching.
