Filtration effect of <i>Cordyceps chanhua</i> mycoderm on bacteria and its transport function on nitrogen.

Abstract

<h4>Importance</h4>During the natural growth of <i>Cordyceps chanhua</i>, it will form a mycoderm structure specialized from hyphae. We found that the bacterial membrane of <i>C. chanhua</i> not only filters environmental bacteria but also absorbs and transports nitrogen elements inside and outside the body of <i>C. chanhua</i>. These findings are of great significance for understanding the stable mechanism of the internal microbial community maintained by <i>C. chanhua</i> and how <i>C. chanhua</i> maintains its own nutritional balance. In addition, this study also enriched our understanding of the differences in bacterial community composition and related bacterial community functions of <i>C. chanhua</i> at different growth stages, which is of great value for understanding the environmental adaptation mechanism, the element distribution network, and the changing process of symbiotic microbial system after <i>Cordyceps</i> fungi infected the host. At the same time, it can also provide a theoretical basis for some important ecological imitation cultivation technology of <i>Cordyceps</i> fungi.
