解釋
arabinoside]阿糖腺苷-
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生長及固氮能力的影響，結果表明，在15 - 40下均能生長並表達固氮酶活性，其最適生長及固氮的溫度為25 - 35 ；能利用葡萄糖、蔗糖、蘋果酸、甘露醇等多種碳源生長並固氮，當培養基中同時存在蔗糖和蘋果酸時，細菌生長和固氮活性最強；在偏酸和偏堿的條件下（ ph4 . 5 - 8 . 5 ）均能保持較強的生長勢和較高的固氮酶活性，並能通過調節自身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濃度對其生長和固氮酶活性影響不大，當naci濃度升至2時，菌株的生長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 -
The hammersmith regatta race is run by an independent committee under ara rules and water safety code. it is a free start, 1400 meters with the tide
鐵匠賽船會賽跑被一個獨立委員會在ara規則和水安全代碼下面運用。它是免費開始，有潮的1400米。 -
The results of rice inoculation experiment in a spermosphere model system with various nitrogen - fixing bacteria suspensions showed that the strain w12 represent highest ara amongst all the strains tested, the differences between it and the other 44 strains were highly significant. moreover, the high ara of the strain w12 associated with different rice genotypes were less varied
通過比較多個菌株與同一水稻基因型的聯合固氮效率及w12與不同基因型的水稻的聯合固氮效率，發現供試菌株中w12與水稻的聯合固氮效率最高，且遠遠高於其它菌株；同時這種高的固氮效率在不同的水稻基因型之間沒有表現出顯著差異。
