摘要
为研究天牛消化利用纤维素的机理 ,利用纤维素 -刚果红琼脂培养基 ,从桑粒肩天牛 (A.germari)幼虫中肠分离到一种兼性厌氧纤维素分解菌。菌落为白色圆形 ,边缘比较规则 ,周围溶纤维素透明圈直径一般可达 10 mm～ 2 0 mm,细菌大小为 0 .5～ 0 .8μm× 1～ 3μm,革兰氏染色阳性 ,杆状 ,极生鞭毛 ,无芽孢。结合生化实验结果 ,初步鉴定该菌株为纤维单孢菌属 (Cellulomonas)。
In order to clarify the cellulose utilizing mechanism of the Cerambycidae, the microorganism in the Apriona germari(Hope) larvae’s gut was cultured and identified. A strain of facultative anaerobic cellulose utilizing bacteria was isolated from the midgut fluid of A. germari larvae with the cellulose congo red agar medium. The colonies of the bacteria were white and round with regular margin. Clear zones of cellulolysis surrounding the colonies might reach 10mm～20mm. The size of the bacteria was 0.5μm～0.8μm×1～3μm approximately. The cell was gram positive rod with polar flagella. It hadn't spores. With the results of biochemical tests, the bacteria were tentatively identified as Cellulomonas.
