摘要
To investigate nutritive values of a feed fermented with basidiomycetes, among the isolated strains, Lyophyllum decastes (Fr.) Sing. was found with the greatest enzyme productivity and rapid mycelial growth in rice straw medium. Optimum temperature, pH and moisture content for mycelial growth and enzyme production of the strain were , respectively. Fifteen days of culture were required for the highest enzyme productivity. Among the sub-materials added, of rice bran and of defatted perilla seeds were effective for the enzyme production, but caused a reduced mycelial growth. The greatest effect of an addition of inorganic salts was obtained with . When 40 mesh or smaller rice straw and steam treatment at were used, the mycelial growth decreased, whereas the enzyme production increased. The mycelial growth and enzyme production increased when was used as the alkali treatment, but decreased with increasing concentration of NaOH. As the fermentation proceeded, the amounts of ash, reducing sugar and total nitrogen increased, but cellulose, lignin and pentosan decreased. When the rice straw was treated with alkali, the amounts of ash, total nitrogen and lignin decreased, but reducing sugar and cellulose increased. At higher NaOH concentration, the variation become greater. The in vitro dry matter digestibility of the products increased from 55.03 % at the beginning of the fermentation to 62.72 % at 45 days after fermentation. The most effective alkali treatment on the digestibility of rice straw was KOH followed by NaOH. However, the digestibility increased with increasing concentration of NaOH. The digestibility of pretreated with alkali increased after fermentation as well.

为了研究用担子菌发酵的饲料的营养价值，在分离的菌株中，Lyophyllum decastes（Fr。）Sing。发现稻草培养基中酶生产力最高，菌丝生长迅速。最佳温度，菌株生长和酶产生的pH和水分含量分别为。需要15天的培养才能获得最高的酶生产力。在添加的子材料中，米糠和脱脂紫苏籽对酶生产有效，但导致菌丝生长减少。添加无机盐的最大效果是用。当使用40目或更小的稻草和蒸汽处理时，菌丝生长减少，而酶的产量增加了。当用作碱处理时菌丝生长和酶产量增加，但随着NaOH浓度的增加而减少。随着发酵的进行，灰分，还原糖和总氮的量增加，但纤维素，木质素和戊聚糖减少。当稻草用碱处理时，灰分，总氮和木质素含量下降，但还原糖和纤维素含量增加。在较高的NaOH浓度下，变化变大。产物的体外干物质消化率从发酵开始时的55.03％增加到发酵后45天时的62.72％。对稻草消化率最有效的碱处理是KOH，然后是NaOH。然而，消化率随着NaOH浓度的增加而增加。发酵后，碱预处理的消化率也增加。
