acetylene reduction test

Nitrogenase activities of 51 Bacillus polymyxa strains were studied by acetylene reduction tests.

用乙炔还原法，研究了从作物根际分离的５１株多粘芽孢杆菌的固氮作用，结果表明：２８株在有氧条件下培养能合成固氮酶并固氮，其中ＨＷ－１菌株固氮酶活性达７８。

In which,4 strains(coded with X1,X2,X3 and X4) with higher nitrogenase activity were finally identified and studied by using acetylene reduction assay with gas chromatogrphy.

从西安地区单播草坪匍茎翦股颖的根际分离到固氮菌株188株,通过气相色谱仪,利用乙炔还原法最终筛选出4株固氮酶活性较高的菌株进行固氮菌部分特性测定及初步对菌株进行鉴定。
