Abstract: Coprinus comatus is a kind of delicious edible mushrooms with high nutritional value, and the demand is increasing. By selecting culture medium formula of Coprinus comatus, the production efficiency of Coprinus comatus was improved, and the reference was provided for Coprinus comatus cultivation. In this study, the effects of three formulas of brown sugar, PD wheat grain and corn flour on the mycelial biomass, the appearance of culture medium, the growth state of hyphae and the nutrient composition were compared to screen the optimal liquid formula of Coprinus comatus. The optimum seed formula (bean stalk 88%, wheat bran 10%, superphosphate 1%, quicklime 1%) was selected by the growth rate and condition of mycelium in the culture material containing wheat kernels, corn cobs and bean straw. Different proportions of corn whiskers were added to the original seed medium to obtain fruiting bodies. Afterward, the formation of fruiting bodies, commercial traits, yield and nutrient composition of Coprinus comatus were analyzed. The results show that the addition of corn flour to the liquid medium is most suitable for mycelial growth. The commercial traits, biotransformation rate and various nutrients of Coprinus comatus obtained in the medium supplemented with corn whiskers were superior to control. Medium containing 4% corn whisker performed well, the biological conversion rate 91.58%, the content of flavonoids was 91.52% higher than the control, and it takes an average of 35 days from covering soil to fruiting body maturity. In summary, the corn flour liquid formula, the wheat grain original formula, and the cultivar formula containing 4% corn whisker could be used as a high-yield and high-efficiency medium formula of Coprinus comatus.
