摘　　要：从土壤、马粪、牛粪等材料中分离出分解纤维素能力较强的高温细菌３个菌群，中温放线菌３株，中温真菌３株。在稻草培养基中，Ｂ１菌群的纤维素酶活力为５．６６ｍｇ·（ｇ·ｈ）－１，Ａ３菌株的纤维素酶活力为６．５５ｍｇ·（ｇ·ｈ）－１，Ｆ３菌株的纤维素酶活力为５．７６ｍｇ·（ｇ·ｈ）－１，稻草经Ｂ１，Ａ３，Ｆ３分解后，其中的粗纤维含量分别降至６．６９％，６．２６％和６．３５％。Three groups of thermophilic cellulolytic bacteria, three strains of cellulolytic actinomyces and three strains of cellulolytic fungi were isolated and screened from soil horse feces and cow feces. Enzyme activity for group B 1 strain A 3 and strain F 3 were 5.66 mg·(g·h) -1 , 6.55 mg·(g·h) -1 and 5.76 mg·(g·h) -1 respectively. And percentage of cellulose in the rice stalk decomposed byB 1 A 3 and F 3 were 6.69%, 6.26% and 6.35 respectively.
