Effect of agricultural and spent mushroom substrate on the mycelial growth of Trametes versicolor

In this study, the effect of different substrates of agricultural by-products on the mycelial growth rate and density of Trametes versicolor (Turkeytail mushroom) was analyzed. We found that pepper stem and rice bran with a mixing ratio of 9:1(v/v) produced the best mycelial growth of 101 mm in 10 days, while a mixing ratio of 8:2 resulted in mycelial growth of 83 mm in 10 days. The control group treated with a 9:1 mixing ratio of oak sawdust and rice bran (v/v) produced mycelial growth of 74 mm in 10 days. The following results are in the order of beanstalk, sesame stem, and perilla stem. After the harvest of the mushrooms, the mycelial growth rate and the density of T. versicolor in each substrate were as follows the group with waste substrate of Pleurotus eryngii and rice bran with a mixing ratio of 9:1(v/v) produced the best result of 76 mm in days, while a mixing ratio of 8:2 produced of 61 mm in 10 days. The control group with a 9:1 ratio of oak sawdust and rice bran produced mycelia of 74 mm in 10 days, while a mixing ratio of 8:2 resulted in mycelia of 59 mm in10 days.

농산부산물과 버섯 수확 후 배지가 구름버섯의 균사생장에 미치는 영향

표고, 느타리, 큰느타리, 팽이, 노루궁뎅이 수확 후 배지에 균사 생장과 밀도를 조사한 결과, 대조구에서 균사 생장이 72 mm/20일이나 처리구에서 느타리 수확 후 배지 고춧대에서 73 mm/20일로 대조구보다 우수하였다. 균사 밀도도 대조구와 비슷한 양상을 나타내었다. 농산부산물 배지이용 버섯 균사생장과 밀도의 영향을 조사한 결과, 대조구 균사 생장이 74 mm/20일, 고춧대에서 101 mm/20일로 대조구보다 우수하였다.
