Abstract: There is an obstacle to doing scientific research on nematophagous fungus Drechmeria coniospora, owing to the shortest growth cycle of the microbe in conventional medium (including PDA, SDAY and CMA) is 13 days at least.  In this study, we utilized LK-100 medium to culture D. coniospora at room temperature, and observed its growth status under microscope. The results showed that growth cycle of D. coniospora on LK-100 medium was only 8 days. Furthermore, the infection efficiency of conidia, obtained from LK-100 medium, to natural host Caenorhabditis elegans was higher than that obtained from conventional fungi media. LK-100 medium, a kind of effective medium, will contribute to the further study of D. coniospora.
