  1. Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments. the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose, sucrose, malic acid, mannitol ), propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum, at a ph range of 4 to 8. 5, at a saline concentration range of 0. 01 % to 1. 5 % ; low nlv " concentration had little effect on its nitrogenase activity. ara could also be detected when it grow in the culture media with 5mmol / l ntv "

    W12菌株對環境因子的適應性研究:無氮培養條件下,測定溫度、碳源、酸堿度、滲透壓對w12生及固氮能力的影響,結果表明,在15 - 40下均能生並表達固氮酶活性,其最適生及固氮的溫度為25 - 35 ;能利用葡萄糖、蔗糖、蘋果酸、甘露醇多種碳源生並固氮,當培養基中同時存在蔗糖和蘋果酸時,細菌生和固氮活性最強;在偏酸和偏堿的條件下( ph4 . 5 - 8 . 5 )均能保持較強的生勢和較高的固氮酶活性,並能通過調代謝平衡並適應環境的酸、堿性變化,使培養液趨于中性:能耐受較高的滲透壓,培養液中卜、 5 naci濃度對其生和固氮酶活性影響不大,當naci濃度升至2時,菌株的生勢及固氮酶活性才有所下降:低濃度的鉸對其固氮酶活性影響不大,在0
