Cathamus tinctorius, Coptis japonica and Asarum sieboldii were tested as substrate for the production of Flammulina velutipes. Among the C. tinctoris , C. japonica and A. sieboldii , C. tinctoris was the best substrate for the production of fruitbody. The effects of addition of C. tinctoris to sawdust substrate resulted in the increased mycelial growth on inoculum culture, 3.1% in ratio of fully culture and shorted one day in culture period. C. tinctoris was decreased 6.1% in ratio of fully culture, 11.0% in ratio of fruitbody productive culm. The addition of C.tinctoris, C.japonica to sawdust substrate increased 134.6%, 114.1% on the yield of the mushroom fruitbody respectively . But A. sieboldii decreased the mycelial growth and pineheading ratio delayed the production of fruitbody.

A composting technique was assessed to enhance efficiency in oyster mushroom substrate. Poplar sawdusts and by-product of winter mushroom added by 10% of rice bran were composted outdoors at $20^{\circ}C$ to $28^{\circ}C$ for 12 days. The duration of fermentation was shortened 3 days in fermented sawdust plot. The yield obtained from waste cotton substrate with fermented poplar sawdust was 742 g, whereas the yield from control 663 g. In addition, the substrate with by-product of winter mushroom was the most effective to composting. It was useful to apply the fermented sawdust and by-product to waste cotton for compost and sporophore production of oyster mushroom.

The availability of enokitake cultural waste for Lentinus edodes cultivation was investigated, although hardwood sawdust has traditionally been used as a substrate for this fungus. Firstly, physiochemical characteristics of cultural waste were analysed. Secondly, mycelial growth characteristics and fruiting yields of L. edodes on waste treated in some methods were determined. Physiochemical characteristics of enokitake cultural waste showed that the millwaste complex was a little degraded by enokitake fungus and suggested the probability that most component lost by enokitake could be rice bran. Mycelia of L. edodes grew and fruited well on waste supplemented by fresh rice bran and Quercus sawdust although didn't on waste only. Mycelial growths of these fungi on waste were accelerated when supplemented by rice bran to the percent of 40(w/w) but decreased or suppressed at above ratios(30, 40%, w/w). Supplementations of oak sawdust at above 40%(w/w) of the waste and rice bran at 20%(w/w) of the sawdust allowed such a good mycelial growth as to be selected as a pertinent mixing ratio for fruiting medium. A fruiting yield on enokitake cultural waste supplemented by oak sawdust (at 40% of the waste, w/w) and rice bran (at 20% of the sawdust, w/w) was not inferior to that on oak sawdust supplemented by rice bran only (at 20% of the sawdust, w/w). These results indicated strongly the potentiality of enokitake cultural waste as raw materials for shiitake cultivating substrates.

The major substrates used in soilless growing media are peat moss and perlite, where peat moss is a limited and expensive natural resource. Determination of appropriate substrates based on technical and economic feasibility is the vital aspect of research and the key to success in any soilless production system. This research work was performed to evaluate different low-cost and sustainable alternative substrate as soilless growing media for horticulture plant. The objective of this study was to compare the effect of sawdust species and steam treatment, for physico-chemical properties and growth of horticultural plant. This study involves the physical and chemical characterization and growth test of four substrate (pine sawdust, oak sawdust, steamed pine sawdust and steamed oak sawdust) in order to evaluate their use as components of growing media. Steamed oak sawdust ($121^{\circ}C$, 30 min) showed adequate physical and chemical properties compared to peat moss for their use as growing media. The growing media were prepared using different mixture proportion to grow Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya Miq. The highest germination, stem length and leaf area of Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya were observed in 30 minute steamed oak sawdust mixture growing media. The steam treatment condition of sawdust used in the growing media significantly positive affected the germination, the stem length and the leaf area.

에르고스테롤(ergosterol)은 고등균류 균사세포막의 중요한 구성 성분으로 이들의 특징 물질이고, 균의 생장에 중요한 기능을 한다. 그러므로 균사 배양체에서 이 물질의 함량을 분석함으로써 고체상 배지 속에 있는 곰팡이의 생채량을 추정할 수 있다. 표고균사의 액체 배양체와 톱밥 배양체를 가지고 에르고스테롤을 분석한 결과, 이 물질의 함량은 균사체의 중량과 직선적 상관관계가 있으면서(r=0.98), 배양기간, 균주, 배지내 수분함량에 따라 달라졌다. 액체배양체에서 에르고스테롤 농도는 10주간 배양된 것이 0.13%로 20주간 배양된 것의 0.1% 보다 높았다. 톱밥배양체에서 이 물질의 농도는 균주와 수분 함량에 따라 0.015~0.042% 범위였다. 표고균주 산림 4호 배양체에서 에르고스테롤 함량은 균주 목-H나 산림 6호의 것보다 건조배지 g당 $20{\sim}140{\mu}g$ 정도 높았다. 이 화확물질의 함량은 표고균사를 수분율이 125%나 175%인 배지에서 배양하였을때 건조배지 g당 $297{\sim}425{\mu}g$/g 였다. 이 양은 수분율이 125%나 225%인 배지에서의 함량, $148{\sim}286{\mu}g$/g 건조배지, 보다 높은 것이다. 에르고스테롤을 분석함으로써 톱밥이나 원목과 같은 고체배지내에 있는 표고 균사량의 추정이 가능하리라 생각한다.

잿빛만가닥버섯의 인공재배법을 개발하고자 국내 외에서 수집한 균주의 균사배양 특성을 검정하고 자실체 발생을 위한 다양한 재배방법을 구명하였다. 잿빛만가닥버섯 9균주를 공시하여 선발한 결과는 다음과 같다. 균사생장속도가 빠르고 균사밀도가 양호한 SPA 202 및 SPA 205균주를 선발하였으며 선발배지는 BC배지가 가장 양호하였다. 인공재배시 참나무톱밥과 포플러톱밥이 균사생장속도가 가장 빠르고 균사밀도가 가장 치밀하였으며 최적배지는 발효톱밥을 사용한 참나무톱밥(Quercus aliena)40%+포플러톱밥(Populus deltoides)40%+미강(Rice bran)10%+밀기울(Wheat bran)10% 배지로서 이 때균사배양적온은 $20-25^{\circ}C$이며 배양기간은 접종 후 50일, 복토 후 7일이 소요되었으며, 원기형성 및 자실체생육기간은 $17-18^{\circ}C$에서 각각 10~11일, 7~8일이 소요되었다. SPA 202균주의 수확적기의 자실체는 갓의 직경이 60mm, 대의 길이가 67mm이며, 수량은1,100ml병당 130g이었으며 SPA 205균주의 수확적기의 자실체는 갓의 직경이 51mm, 대의 길이가 81mm, 129g이었다. 잿빛만가닥버섯 인공재배 결과, 배지는 발효톱밥 처리구가 미발효톱밥 처리구보다 수량이 많아 SPA 202균주와 SPA 205균주가 가장 양호한 균주로 선발되었다.

느타리버섯 자실체의 형성과정에서 생육 및 미세구조에 미치는 배지기재의 영향을 검토한 결과, 배지의 종류에 따른 초발이소요일수는 폐면이 5일로 가장 빨랐고 볏짚은 대조와 같이 6일이었다. 볏짚과 폐면에서 생육한 느타리의 경도는 대조의 5715.4 $g/cm^2$에 비해 1/2정도로 낮게 나타났으나 톱밥 단독배지에서 생육한 느타리의 경도는 17067.3 $g/cm^2$으로 3배이상의 높은 경도를 나타내어 톱방이 느타리버섯의 경도에 큰 영향을 미치는 것으로 생각된다. 배지별 느타리자실체의 갓부위를 관찰한 결과, 톱밥배지의 경우 다른 자실체의 주름으로부터 비산된 담자포자들이 대량으로 떨어져 있는 것이 관찰되었으며, 볏짚배지의 경우 갓낭상체의 발달이 관찰되었으며 폐면에서 생육한 자실체의 갓의 균사와 노화가 다른 처리에 비해 빠르게 진행되어 있는 것이 관찰되었다. 또한, 톱밥 및 폐면에서 생육한 자실체의 갓의 균사의 노화가 다른 처리에 비해 빠르게 진행되어 있는 것이 관찰되었다. 또한, 톱밥 및 폐면에서 생육시킨 느타리자실체의 담자기의 자가분해 및 담자포자 비산이 빠르게 진행되었음을 확인 하였다. 톱밥배지에서 생육시킨 느타리자실체의 대부의 균사의 생육상태는 두꺼운 균사다발이 대부위 전체를 피복한 듯한 형태가 관찰되어 이러한 균사다발층이 대의 경도를 높이는 요인으로 작용했을 것으로 판단되며, 대조군에서는 풍부한 세포질 물질을 갖는 균사들이 관찰된데 반해, 톱밥에서 생육시킨 느타리자실체의 균사는 다른 처리에 비해 착색이 많이 되어 있는 균사와 액포화된 균사의 발달이 두드러짐을 확인하였다.

Development of efficient substrate formulas to improve yield and shorten production time is one of the prerequisites for commercial cultivation of edible mushrooms. In this study, fifteen substrate formulas consisting of varying ratios of palm press fibre (PPF), mahogany sawdust (MS), Gmelina sawdust, wheat bran (WB), and fixed proportions of 1% calcium carbonate ($CaCO_3$) and 1% sucrose were assessed for efficient Lentinus squarrosulus production. Proximate compositions of mushrooms produced on the different substrate formulas were also analysed and compared. Substrate formulations containing 85% PPF, 13% WB, 1% $CaCO_3$, and 1% sucrose were found to produce the highest carpophore yield, biological efficiency and size (206.5 g/kg, 61.96%, and 7.26 g, respectively). Days to production (first harvest) tended to increase with an increase in the amount of WB in the substrate formulas, except for PPF based formulas. The addition of WB in amounts equivalent to 8~18% in substrate formulas containing 80~90% PPF resulted in a decrease in the time to first harvest by an average of 17.7 days compared to 80~90% MS with similar treatment. Nutritional content of mushrooms was affected by the different substrate formulas. Protein content was high for mushrooms produced on formulas containing PPF as the basal substrate. Thus, formulas comprising PPF, WB, $CaCO_3$, and sucrose at 85% : 13% : 1% : 1%) respectively could be explored as starter basal ingredients for efficient large scale production of L. squarrosulus.

A method of spawn making procedures through the application of fermented sawdust for the purpose of avoiding contamination by undesirable fungi in the course of Pleurotus ostreatus mycelial growth was evaluated. Of three kinds of supplements, rice bran was the most effective to raise temperature up to $70^{\circ}C$. Mycelial activity and density was more considerably improved in the case of using fermented sawdust supplemented with rice bran than the case of non-fermented sawdust. Primordia of Pleurotus ostreatus were formed on fermented sawdust. The substrate of fermented sawdust showed potential to prevent the growth of Trichoderma sp. which caused a symptom on mushroom mycelium, whereas there was nothing to inhibit the growth of Trichoderma sp. during 30 days after inoculation in non-fermented sawdust.
