固氮细菌
Symbiotic nitrogen fixation of legumes with azotobacteria was a hot topic of scientific research, but less focus on alpine meadow community.
豆科植物的共生固氮作用一直是科学研究的热点问题,但在高寒草甸上研究的比较少。
The azotobacteria in the rhizosphere of Leymus chinensis and Agropyron mongolica were separateda, nd their activities were measured by the methods of dilution-plate method and etylene reduction assay.
利用平板划线法和乙炔还原法对羊草和冰草根际固氮菌进行分离和固氮活性的测定。
“Azotobacteria”的正确拼写应为Azotobacter(固氮菌属),属于一类重要的固氮细菌。以下是详细解释:
Azotobacter是革兰氏阴性、需氧的细菌属,广泛存在于土壤和水中。其名称源自希腊语“azoto”(氮)和“bacter”(杆状),意为“固氮的杆状微生物”。
普通“bacteria”泛指所有细菌(如、5所述),而Azotobacter特指具有固氮功能的属级分类单元,学术语境中需明确区分。
若需进一步了解其酶活性或具体菌种分离方法,可参考微生物学专业文献或词典来源(如)。
“azotobacteria”是指一类可以将空气中的氮气转化为可用于植物生长的氨的细菌。以下是该单词的详细解释:
