【中文摘要】 本文報(bào)道了草菇培養(yǎng)料中分離得到的一株對(duì)菇類有益的細(xì)菌(暫稱864菌)。研究結(jié)果表明,該菌株系革蘭氏陰性桿菌,細(xì)胞大小為0.5～0.8×0.9～1.1μm,細(xì)胞外壁有莢膜,周身鞭毛;在Ashby氏無氮培養(yǎng)基上,菌落呈圓形,中稍突,面包狀,表面光滑,邊緣整齊,有閃光,粘稠;好氧、最適生長pH為7,最適生長溫度為30℃;能固定空氣中的氮素,供菇類菌絲利用;菌液含有多糖、蛋白質(zhì)、纖維素等菇類營養(yǎng);分泌物含有刺激素,能促進(jìn)菌絲扭結(jié),子實(shí)體發(fā)育,添加864菌液培養(yǎng)料的產(chǎn)量與傳統(tǒng)發(fā)酵培養(yǎng)料的相比:草菇提高了20.33～42.67%;姬松茸菇提高了54.3%;蘑菇提高了40.7～83.27%;金針菇提高了14.38％。

【英文摘要】 A bacterial strain (named as 864) which is beneficial to mushroom growth has been isolated from the compost of Volvariella voluacea. The investigation results indicate that this strain is a Gram negative bacillus, its cell size is 0.5-0.8×0.9-1.1μ, with sheath and peritrichate. In Ashby N-free medium, its colony is round-shaped, projecting in center, bread shaped, smooth on surface, neat in edge, lustrous and sticky. 864 strain is aerobic, its optimum pH is 7 and optimum growing temperature is 30℃ It can fix nitrogen from atmosphere and the fixed nitrogen can be further utilized by mushroom mycelia. The bacterial growing solution contains polysaccharides, protein arid vitamincs which provide nutrition for mushroom growth. Its secretions contain hormones which can stimulate the twisting of mycelia and the development of fruit bodies to receive higher yield. Compared with traditional fermentation composts, the yields of 864 strain-added composts for Volvariella volvacea, Agaricus biazei ...更多Murvill, Agaricus bisporus and Flammulina velutipes increase 20.33-42.67, 54.3, 40.7-83.27 and 14.38% respectively.  還原
