【摘要】

：

上向流式生物膜反应器被用来作为启动半亚硝化和厌氧氨氧化的反应装置.一体化反应器启动之前是已经培养成功的上流式厌氧氨氧化反应装置,通过调节溶解氧、pH、加入氨氮的浓度、水力停留时间最终经过143d成功启动了部分亚硝化和厌氧氨氧化反应器.试验结果显示,水力停留时间7h,进水溶解氧控制在0.51 mg/L～2.1 mg/L,进水pH为7.6-8.0,氨氮浓度为100 mg/L是一体化成功启动的最佳条件.

食品添加剂亚硫酸盐可增加肝细胞内甘油三酯含量并促进极低密度脂蛋白分泌

文献报道亚硫酸盐接触可引起受试小鼠肝细胞内小脂滴数量明显增加和甘油三酯含量增加,推测其原因可能是抑制了肝细胞极低密度脂蛋白的分泌,我们采用体外实验进行了探讨.结果发现,亚硫酸盐可以抑制肝细胞内肉碱酰基转移酶1的基因和蛋白表达,增加肝细胞内甘油三酯含量增加,提示亚硫酸盐可能通过抑制肝细胞脂肪酸β-氧化导致肝细胞内脂肪积累.
