Nitrogenase activity, determined by the acetylene reduction assay, in soybean cell suspensions infected with Rhizobium, was stimulated significantly by the addition of succinic acid or glutamine. Acetylene-dependent ethylene values as high as 4.6 mumoles of ethylene/gram dry weight.hour were observed.
固氮酶活性通过乙炔还原测定法来确定,在被根瘤菌感染的大豆细胞悬浮液中,琥珀酸或谷氨酰胺的添加显著刺激了其活性。观察到高达 4.6 微摩尔乙烯/克干重小时的乙炔依赖性乙烯值。
