The objective of this study was to determine effects of corn germ meal(CGM) and condensed molasses fermentation solubles(CMS) as the replacement of rice bran on mycelial growth and density in various mushrooms. The results of this study showed that CGM and CMS might be utilized more efficiently than rice bran in culturing mushrooms. The results are as follows; 1. Mycelial growth of Pleurotus ostreatus was remarkably higher than that of control when the concentration of CGM and CMS was 10%, respectively. However, the mycelial density was lower than that of control. Thus, Considering the mycelial growth as well as density, it was found that 20% supplements of CGM and CMS resulted in the best with 78mm/10d and 71mm/10d, respectively. 2. Mycelial growth of Pleurotus eryngii in the treatment group of 10% CMS and 20% CGM showed 74mm/10d and 67mm/10d, respectively. This result tended to be equal or somewhat lower compared with that of control(74mm/10d). 3. Mycelial growth of Flamulina velutipes was 87mm/10d in the treatment of 10% CMS, 79mm/10d in the treatment of 20% CGM, which showed significantly higher than that of control(56mm/10d). When the contents of CGM and CMS were mixed with the amount of 10-30%, Thus, it was assumed that the quantity of mushrooms may increase with the supplements of CEM and CMS. 4. Mycelial growth of Lentinus edodes in the treatment group of 10-40% CMS and 10-30% CGM showed 58-52mm/10d and 56-49mm/10d, respectively. This result was significantly higher that control(47mm/10d). 5. When CMS and CGM were supplememted with the level of 10-30%, mycelial growth rate of Ganoderma lucidum showed 76-72mm/10d and 74-69mm/10d, respectively, which are higher than those of control.

버섯 생산량에 의한 배지 소요량 추정

장현유,Chang, Hyun-You 국립한국농수산대학교 교육개발센터 2009 현장농업연구지 = Journal of practical agricultural resear Vol.11 No.1

Required total substrates amounts for mushroom production are 212,186M/T in Korea. 80% of these total substrates amounts, 169,748 M/T is used for main substrates. Also 20%of these total substrates amounts, 42,438 M/T is used for additives. Main substrates 169,748 M/T is composed of sawdust, waste cotton, cotton seed hull, straw and com cob etc.. Additives 42,438 M/T is composed of rice bran, wheat bran and beet pulp etc. In the mushroom management, the cost of substrates purchase is composed for the most of management. Substrates amount is limited to supply, and the demand of mushroom substrates is on the increase continuously. So there is nothing but the cost of substrates are raising. Therefore the most important thing must develop the cheap substrates for the mushroom production.

장현유,구자준,Chang, Hyun-You,Goo, Ja-Joon 한국버섯학회 2005 한국버섯학회지 Vol.3 No.1

고활성칼슘은 패각류를 고온($1,500{\sim}5,000^{\circ}C$)에서 고전압(약 15,000V)의 전기를 통하여 전기분해해서 생산하는 산화칼슘이며, 제품의 순도가 대단히 높고 독성이 전무하며, 분자간의 결합력을 약화시켜 생체 내 활성도와 용해도가 탁월한 물질이다. 이의 버섯의 생육단계별 고활성칼슘 처리효과는 다음과 같다. 느타리버섯은 배지 수분조절시 혼합할 때 균사배양일수가 2일 단축, 초발이 소요일수는 1일 빠르고, 유효발이경수가 15개, 개체중이 148g/850cc로 6.5% 증수되었다. 큰느타리버섯은 배지 수분조절시 혼합할 때 균사배양일수가 3일 단축, 초발이 소요일수는 1일 빠르고, 생육소요일수가 6일간 단축, 개체중이 108.1g/850cc로 9.7% 증수되었다. 팽이버섯은 균긁기 시 처리가 가장 좋았다. 균사배양일수가 2일 단축, 초발이 소요일수는 3일 빠르고, 생육기간은 1일 빠르며, 재배기간은 3일간 단축, 개체중이 165g/850cc로 6.7% 증수되었다. 표고는 배지 혼합시 배양일수가 3일, 갈변화 시작일이 2일, 첫수확 소요일수가 4일 단축되며, 수량은 169g/2kg으로 9.7% 증수되었다. Highly Activated Calcium(below HAC) is the oxidized calcium made by dissolving shell materials with high voltage about 15,000V and high temperature ($1,500{\sim}5,000^{\circ}C$). This HAC is a material with a very high degree of purity without toxicant. This HAC decreases chemical reaction so the degree of being active and dissolving living material is outstanding. The effects of HAC on the propagation of mushrooms are following. In the case of the Pleurotus ostreatus, when controlling media moisture by mixing with the HAC, mycelium cultivating days were shortened by 2days. The day required for primordial formation after inoculation(DPI) were one day faster. The number of stem was 15 and individual weight was 248g/850cc, a 6.5% increase. In the case of Pleurotus eryngii, when controlling media moisture by mixing with the highly activated calcium, mycelium cultivating days were shortened by 3days. DPI were l day faster. The day required for colonization after inoculation was shortened by 6days and individual weight was 108.8g/850cc, a 9.7% increase. In the case of Flammulina velutipes, the highly activated calcium was the best for scraping up mycelium. Mycelium incubating days were shortened by 2days. DPI were shortened by 3days. The day required for colonization after inoculation was 1day faster and the period of cultivation was shortened by 3days. Individual weight was 165g/850cc, a 6.7% increase. In the case of Lentinula edodes, when mixing media with the highly cultivated calcium, cultivating days were shortened by 3 days. The days for becoming brown in color were 2 days faster and the days of the first harvest were shortened by 4 days. The weight of mushrooms was 169g/2kg, a 9.7% increase.
