Growth Regularity ofAnabaena flos-aquae in Different Complex Iron Environment
摘要
Abstract
Anabaena flos-aquae were cultured separately in ferric ammonium citrate, EDTA-Fe, ferrioxalate and ferric humate in the initial concentration of 0.2 mg/L, 0.4 mg/L, 0.6 mg/L, 0.8 mg/L and 1.0 mg/L by using the laboratory simulation training method. The results show that the bioavailability of ferric ammonium citrate and ferric humate is stronger than the EDTA-Fe, and ferrioxalate under the same complex iron concentration in water. And the algae shows a faster growth rate and greater average growth rate in ferric ammonium citrate and ferric humate, but the promoting effect is slightly different due to the difference of the concentration of the complex iron. The optimum growth of iron concentration of ferric ammonium citrate is 0.2 mg/L, and the optimum growth of iron concentration of EDTA-Feand ferrioxalate appeares in the vicinity of 0.6 mg/L, while the optimum growth of iron concentration of ferric humate appeares in the vicinity of 0.4 mg/L.关键词
