auxotrophic

auxotrophic，音标为["ɔːkəʊtəʊfl]，基本翻译为“自养生物”或“需氧营养物”。速记技巧可以考虑使用谐音记忆，如“奥特疯”或“奥克头佛”。

Auxotrophic这个词的词源可以追溯到拉丁语和希腊语，意为“需要营养的”。这个词是由“auxin”（营养）和“trope”（转移）两个词组合而成的。

英文小作文：

Being auxotrophic is a unique characteristic of bacteria that determines their growth requirements. Auxotrophic bacteria require specific nutrients for growth, which makes them an excellent tool for studying the genetics of microorganisms and exploring their adaptability to different environments. In biotechnology, auxotrophic bacteria are often used to produce valuable compounds and improve industrial processes. In addition, auxotrophy is also an important factor in determining the fitness of bacteria in the natural world, which helps us better understand the interactions between microorganisms and their environments.
