黑粉虫与黄粉虫幼虫肠道细菌的比较

Comparison of bacteria isolated from gastrointestinal tact of Tenebrio obscurus and T.molitor

在黑粉虫和黄粉虫肠道中分别分离获得5株细菌,对其菌体形态、培养性状、染色反应、生理生化反应等进行了系统研究。鉴定结果表明,黑粉虫的5个细菌菌株分别属于金杆菌属(Aureobacterium)、李斯特氏菌属(Listeria)、微杆菌属(M i-crobacterium)、莫拉氏菌属(M oraxella)、短小杆菌属(Curtobacterium);黄粉虫的5个细菌菌株分别属于金杆菌属(Aureobacte-rium)、球形芽孢杆菌(Bacillus sphaericus)、微杆菌属(M icrobacterium)、巨大芽孢杆菌(B.m egaterium)、短小杆菌属(Curtobac-terium)。金杆菌属(Aureobacterium)、微杆菌属(M icrobacterium)和短小杆菌属(Curtobacterium)均在2种昆虫肠道中出现。

Five bacterium strains of were isolated from each larvae intestine of Tenebrio obscurus and T. molitor and they were identified based on the characters of morphology, cultivation, dyeing, physiology and biochemistry. As a result, the bacteria from T. obscurus were belonging to Aureobacterium, Listeria, Microbacterium, Moraxella and Curtobacterium, respectively; and those from T. molitor were belonging to Aureobacterium, Bacillus （ B. sphaericus and B. megaterium ） Microbacterium and Curtobacterium, respectively. Aureobacterium, Microbacterium and Curtobacterium could be isolated from gastrointestinal tracts of both the two mealworms.
