The isolates of microorganisms from the rhizosphere of spring barley plants and soil at the use of analytical selection method was isolated. Its isolates on the ability of "nitrogen-fixing activity" was tested. It was shown that isolates of microorganisms had different of the colonies formed and cultural growth on the Eshbi's selective medium as well as the ability to fixing of molecular nitrogen. The different levels of intensity and dynamics of isolates nitrogenase activity in vitro were identified. New isolates of the soil microorganisms complement of the gene pool diazotrophic bacteria. Its isolates are perspectivity for the study as the basis or components of the bacterial fertilizers for the crops.
利用分析筛选法从春大麦植物根际和土壤中分离出微生物菌株。对其菌株的“固氮活性”能力进行了测试。结果表明，微生物菌株在埃什比选择性培养基上形成的菌落和培养生长情况不同，以及固定分子氮的能力也不同。确定了体外菌株固氮酶活性的不同强度水平和动态变化。土壤微生物新菌株补充了固氮细菌的基因库。其菌株作为作物细菌肥料的基础或成分具有研究前景。
