对22株相思根瘤菌菌株进行生理生化特征的初步研究,这些菌株基本符合Jordan和Allen的根瘤菌分类特征,但其中10株菌株能利用柠檬酸.同时这些菌株利用糖的能力不同,几乎所有的菌株均能利用D-果糖、木糖、山梨醇和糊精,但对其他糖类如麦芽糖、D-半乳糖、棉子糖、鼠李糖和阿拉伯糖则是有的菌株可以利用,有的不能.本研究为进一步的深入研究和应用奠定了基础. A preliminary study on the physiological and biochemical characteristics of 22 strains of Acacia rhizobia showed that these strains were basically in accordance with the classification of rhizobia of Jordan and Allen, but 10 of them could utilize citric acid, while the ability of these strains to utilize sugar was different. Almost all Strain can use D-fructose, xylose, sorbitol and dextrin, but for other sugars such as maltose, D-galactose, raffinose, rhamnose and arabinose are some strains can be used, and some can not The research laid the foundation for further research and application.
