为了研究白腹皮蠹幼虫肠道环境中的细菌种类,从中分离、纯化、培养,获得6个细菌菌株,对其培养性状、染色反应、菌体形态、生理生化反应进行系统研究。鉴定结果表明,上述6个细菌菌株分别属于坚强芽孢杆菌(Bacillus firmus)、气微菌属(Aeromicrobium Miller,Woese and Brenner,1978)、浸麻芽孢杆菌(Bacillus macerans)、葡萄球菌属(Staphylococcus Rosenback,1884)、巨大芽孢杆菌(Bacillus megaterium)和短芽孢杆菌(Bacillus brevis)。从白腹皮蠹肠道环境中分离出6个菌株,鉴定出分类地位,菌株之间的数量存在明显差异,以巨大芽孢杆菌数量最多(5.32×1019),需要进一步研究该6个菌株在白腹皮蠹肠道环境中的具体作用,以期寻求有效防治白腹皮蠹的新途径。
Six bacterial strains were isolated, purified and cultured in order to study the bacterial species in the intestinal environment of white beetle larvae. The culture traits, the staining reaction, the cell morphology and the physiological and biochemical reactions were systematically studied. The results showed that the above six bacterial strains belong to Bacillus firmus, Aeromicrobium Miller (Woese and Brenner, 1978), Bacillus macerans, Staphylococcus Rosenback 1884), Bacillus megaterium and Bacillus brevis. Six strains were isolated from the intestinal environment of B. burgdorferi and the taxonomic status was identified. There was a significant difference in the number of isolates between them, with the largest number of Bacillus megaterium (5.32 × 1019) Abdominal mite intestinal environment specific role in order to seek effective ways to prevent white beetle new ways.
