Curto等(1972)在检测蘑菇培养料中活的有机体时,曾提到棕色固氮菌、贝氏固氮菌和含油真菌等具有增产潜力.一般认为,在蘑菇栽培过程中,各种环境条件都有利于固氮菌发挥固氮作用.为今后蘑菇栽培中筛选和应用优良的固氮菌株,我们在蘑菇栽培过程的各个阶段,对固氮菌的存在及其固氮酶活性的变化作了研究,现将结果报道如下.一、材料与方法(一)材料①菌种:83号菌株,由闽侯荆溪乡菌
Curto et al. (1972) mentioned the potentials of yield enhancement when detecting the living organisms in mushroom culture materials, such as Azotobacter vinelandii, Azotobacter vinelandii and oil-bearing fungi etc. It is generally believed that during the cultivation of mushrooms, various environmental conditions have Which will help Azotobacter play a role in nitrogen fixation.For screening and application of good nitrogen-fixing strains in mushroom cultivation in the future, we studied the existence of nitrogen-fixing bacteria and the changes of nitrogenase activity in the various stages of mushroom cultivation process, and the results are reported as follows First, the material and methods (A) material ① strain: 83 strains, Minhou Jingxi Township from the bacteria
