Abstract:
      Research was conducted to observe the impact of Na+ ion on silieon(Si) and phosphorus(P)dissolved by Rs-2 and Rs-4 strains. The results indicated that NaCl condition could improve Si dissolved by Rs-2 strains and Rs-4 strains. When Rs-4 strains were cultivated 72 hours, concentration of dissolution Si reached 106.92 μg/mL under 1.5% NaCl, and 148.9 μg/mL by Rs-2 strains uhder 3% NaCl. Then, NaCl condition could facilitate dissolution P capacity of Rs-4 strains, after 72 h, concentration of dissolution P reached 115.68 μg/mL under 3% NaCl. Further-more, based on the changing with time, dissolution Si character of Rs-2 strains accorded with Logistic curve type, and regression analysis showed that dissolved silicon and time was in positive correlation and had significant relationship. Followed dissolution P character of Rs-4 strains accorded with binomial type, and had very significant relationship and high reliability.
