You are examining the chemical constituent profile for an unknown structure. You read that the structure contains significant amounts of the chemical dipicolinic acid吡啶二羧酸. Based on this information, what do you suspect the structure is?
A. gram-positive bacterium
B. endospore C. gram-negative bacterium
D. archaeon
答案是B哈,
翻译大概是是我们检查一种未知结构的化学成分.我们知道这种结构含有吡啶二羧酸.根据这个信息,我们猜测是这种结构是什么?
A格兰仕阳性细菌
B芽孢
C格兰仕阴性细菌
D第三类有机体 (一种不依靠太阳的光和热而生活在沸点温度的细菌)
而ACD均为一类细菌,而B为芽孢,是细菌的特殊结构的一种,也是细菌的休眠形式,由于芽孢形成时可同时形成2,6-吡啶二羧酸,而该物质有含有吡啶二羧酸,故选B.
其实我认为这不是医学微生物的题吧,应该是生物学微生物题,呵呵.但愿我没做错.
