设计了新的方法驯化取自榨菜废水处理厂的活性污泥,获得了异养硝化-好氧反硝化(HN-AD)菌OTU数量分别为1500和7500的HW1、HW2两种活性污泥。以高盐榨菜废水为处理对象,设置了HN-AD菌OTU数量分别为0、1500、7500的三组实验(S1、S2、S3),对比研究了阴极接种污泥HN-AD菌OTU数量对单室MFC启动的产电及污染物去除性能影响。结果显示,S3实验组启动单室MFC具有较好的脱氮性能,产电结束后NH_(4)^(+)-N及TN的去除率分别达到了(90.13±2.55)%与(90.83±1.46)%。S1实验组的最高输出电压[(0.4972±0.0335)V]、最大功率密度(11.59 W/m^(3))、最大电流密度(56.35 A/m^(3))、产电周期(116 h)及库仑效率[(16.27±0.47)%]均大于S2和S3,但是前者的NH_(4)^(+)-N及TN去除率分别仅为(6.84±1.09)%与(6.20±0.60)%,均低于后者。HN-AD菌OTU数量对单室MFC启动时的COD去除性能无显著影响。

Huayouza 6, a new semi-winter Brassica napus variety with high-yield, good quality, prematufity and extensive adaptability, was derived from the cross between the female parent 8086A and male parent 7-5. Two cDNA-based Arabidopisis microarray were used to analyze gene differential expression in bud of an elite *** hybrid Huayouza6 and its parents, in which there were 83 over-expression transcripts and 331 under-expression transcripts between Huayouza 6 and its female parent 8086A and 94 over-expression transcripts, and 423 under-expression transcripts were demonstrated between Huayouza 6 and its male parent 7-5. Further analysis showed that there were significant number of genes responsible for photosynthesis, and its implication for heterosis was discussed. Northern analysis of phosphoribulokinase coincided with its expression pattern derived from hybridization of Arabidopsis cDNA microarray and B. napus mRNA, this system of heterologous hybridization analysis should be applicable to other close relatives of Arabidopsis thaliana.
