| Summary: | Effects of diverse environmental factors on the growth and nitrogenase activity of a nitrogenfixing bacteria strain W12 were investigated in our experiment. The results showed that W12 was capable of using various carbon sources, propagated quickly and exhibited quite high nitrogenase activity under a range of temperature, pH and sodium chloride concentration conditions: 15-40 ℃, pH4-8.5, 0.01-1.5% NaCl. Nitrogenase activity could was also detected when W12 was cultured in the media containing 5 mmol/L NH<sub>4</sub><sup>+</sup>. Accordingly, so far as its rapid growth and high nitrogen fixation activity were confident that W12 could easily adapt itself to diverse cultural environmental conditions and thus seems to be a promising inoculant in agricultural production. |
