A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.

采用浸没式膜生物反应器处理焦化废水的试验结果表明：膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力，其去除氨氮的最高负荷为0.19kg/(m3·d)，出水氨氮＜1mg/L(去除率为99%)；泥龄长可能使微生物的代谢产物或其他大分子物质积累，从而抑制硝酸盐细菌的活性，导致NO2-积累而有利于短程脱氮的进行，但泥龄过长也会影响亚硝酸盐细菌的活性，从而影响对氨氮的处理效果。

Iba 2002. Both the Arabidopsis fad5 mutant, which lacks an active chloroplast x-9 fatty acid desaturase and accumulates high levels of palmitic acid (16:0), and the fad6 mutant, which lacks an active x-6 fatty acid desaturase and accumulates high levels of palmitoleic acid (16:1) and oleic acid (18:1), have reduced levels of polyunsaturated fatty acids in the chloroplast galactolipids.

两个拟南芥突变体的叶绿体半乳糖脂含有较少的多不饱和脂肪酸：一种是拟南芥fad5突变体，它缺乏有活性的叶绿体的X-9脂肪酸去饱和酶，因而积累了高浓度的棕榈酸（ 16：0 ）；另一种是拟南芥fad6突变体，它缺乏一个有活性的 X - 6脂肪酸脱氢酶因而积累了高浓度的软脂酸（ 16：1 ）和油酸（ 18：1 ）。
