Pseudomonas sp. HS-2降解双酚F及脱氮的特性研究
Gongye shui chuli, 2018 Pseudomonas sp． HS-2能以双酚F为唯一碳源、NH4+-N为唯一氮源进行生长，并通过异养硝化好氧反硝化过程脱氮。在35℃，150 r/min和pH=7.0条件下，考察了菌株HS-2降解双酚F的能力及其脱氮性能。结果表明，菌株HS-2能够降解500 mg/L双酚F。并且在最适碳氮比为20的条件下，双酚F和NH4+-N的去除率可分别达到99%和96%。并且发现氨单加氧酶参与了双酚F的降解。氮平衡分析表明，47.7%的初始NH4+-N转化为N2。外加柠檬酸钠或硝态氮对双酚F和NH4 ...
