This study was conducted to verify the cause of suppression symptom in mycelial growth during summer and to be able to establish a countermeasure. Cultivation of Flammulina velutipes was experimented with varying elapsed time of 0, 3, 6, 9 hours after mixing the sawdust media and two kinds of water temperature (normal water, 24℃ and cold water, 6℃) for mixing sawdust media. There were trends of increased media temperature from 24℃ to 31℃ and decreased pH from 6.5 to 5.2∼5.6 with varying elapsed time from mixing the media to sterilization. Bacterial density also increased with bacterial density in Medium 24℃ being 1.9∼4.1 times higher than that in Medium 6. Growth of F. velutipes was delayed with dual culture of bacteria isolated from sawdust media. Total nitrogen content of sawdust media was lowered by elapsed time from mixing the media to sterilization. The use of normal water(24℃) delayed mushroom growth by 1∼2 days compared with that of cold water(6℃). Furthermore, mycelial growth of F. velutipes in the bottle cultivation ceased 9 hours after mixing the media. Primordia formation of F. velutipes was delayed by 1∼3 days by elapsed time after mixing sawdust media, while fruit-body yield decreased by 7∼12% 6 hours after mixing the media. Fruit-body yield was more stabilized with the use of cold water(6℃) than with that of normal water(24℃). Results showed that it is effective to use cold water as low as 6℃ in mixing media for F. velutipes cultivation, especially during summer when environmental temperature is high, high pressure sterilization after bottling work can prevent bacterial propagation in the media and can stabilize media ingredient.
