Abstract

Ten to thirty percent of ginko leaf pomace(GLP) were added to pine sawdust to investigate mycelial growth. Mycelial growth on the medium with GLP was 86~101(mm/28 days) and was slower than that of the control without GLP as, 102(mm/28 days). Mycelial growth time on medium of sawdust with 10 to 20% GLP was similar to the control without GLP as 29 days but that on medium with 30% GLP was delayed for 2 days. The time of pinhead formations of sawdust with 10 to 20% GLP was 7 days, the growth time to harvest was 11 days. These results were similar to those of the control without GLP. The sizes of pileus of treatments with 10 to 30% GLP were tend to be smaller compared with the control. The length of stipe of 10% GLP treatment was 98mm which was longer than that of the control with 91mm. The thickness of stipes of 10 to 30% GLP treatments were 45 to 48mm which were tend to be thicker than that of the control with 45mm. The hardness of stipe were 35,062($g/cm^2$) to 4,1065($g/cm^2$)) which were harder than that of the control with 32,156($g/cm^2$)). GLP treatments seem to be favorable to store or distribute. Yields per volume of GLP added treatments were 88.7g to 95.6g, which was increased 3 to 12% compare to 85.8g of the control without GLP.

최근 국제원자재가 상승에 따라 버섯 배지 가격이 50% 이상 상승하여 톱밥 대체 배지의 개발이 절실한 실정으로 충남도내에서 생산되는 은행잎부산물을 이용하여 버섯 배지로 개발하여 생산비 절감 및 경제적 이익 창출을 도모하기 위해 수행한 결과를 요약하면 다음과 같다. 은행잎박을 10~30% 첨가량에 따른 균사생장은 대조구 102 mm/28일에 비해 은행잎박 10~30% 첨가시 86~101mm/28일로 균사생장이 느린 경향이었으며, 균배양일수는 은행잎박 10~20% 첨가시 29일로 대조구와 같았다. 초발이 소요일수는 은행잎박 10~20% 첨가시 7일, 생육 일수는 11일로 대조구와 같았지만, 은행잎박 30% 첨가시 초발이소요일수는 1일정도 늦었다. 갓의 크기는 은행잎박 첨가시 대조구에 비해 작은 경향이 있었고, 대의 길이는 은행잎박 10% 첨가시 98mm로 대조구 91mm에 비해 길었다. 대의 두께는 대조구 45mm에 비해 은행잎박 10~30% 첨가시 45~48mm로 두꺼운 경향이었다. 대의 경도는 대조구 32,156($g/cm^2$)에 비해 은행잎박 10~30% 첨가시 $35,062g/cm^2{\sim}41,065g/cm^2$로 높아 저장 및 유통에 유리하였고, 병당 수량은 대조구 85.8g/병에 비해 은행잎박 10~30% 첨가시 88.7~95.6g/병으로 3~11% 증수되었다. 따라서 큰느타리 병재배시 은행잎박 10%를 첨가하는 것이 수량 증수 효과가 있는 것으로 사료된다.
