以两座大型污水处理厂为研究对象,分析了悬浮填料对生物处理系统的强化效果。结果表明,投加悬浮填料对有机物的削减能力影响不大,但提高了系统的抗冲击性能。投加填料促进了硝化菌的富集,但菌属类型受投加位置影响,填料位于好氧池前段有利于氨氧化菌(norank_f__JG30-KF-CM45和Ellin6067)的富集,位于后段则利于亚硝酸盐氧化菌(Nitrospira)的富集。悬浮填料提高了系统中反硝化菌的种类和丰度,并富集了好氧反硝化菌(Hyphomicrobium、Flavobacterium和Dokdonella),一定程度上提高了工艺的脱氮性能。值得注意的是,悬浮填料易于实现反硝化聚磷菌(DPB)的富集,可使DPB在聚磷菌(PAOs)中的占比达71.3%及以上。

中国口腔颌面外科杂志 2008年第B5期6卷 67-68页

作者： ting Ge chuan Jun Chen Department of Oral and Maxillofacial Surgery Third affiliated Hospital of Anhui ~ledical University Hefei 230061Anhui ProcinceChina

Purpose: To clone the Human Papillomavirus E5 gene and analyze the features of its gene sequences and make a prokaryotic expression of E5 to investigate the biological properties of its expressive protein。Methods: The DNA was extracted from ten tissue samples of uterine cervix cancer。HPVI6 E5 gene was amplified by Nested-PCR and sequence analysis demonstrated the full-length gene fragment of it。HPV16 E5 was inserted into the pET32a (+) to construct a prokaryotic expression plasmid。The expression plasmids were transferred into competent E。coli BL21 and Rossatta。The recombined bacterium, BL21/E5, was induced with IPTG。HPVI6 E5 recombinant protein expression was checked and analyzed by SDS-PAGE and Western blotting。Results: The HPV16E5 gene was successfully cloned and the expression plasmid that pET32a (+)-E5 was constructed smoothly。Induced with IPTG, the fusion protein of HPVI6 E5 was expressed efficiently in BL21and Rossatta。Western blot showed that the fusion protein was about 26KD。Conclusions: the HPV 16 E5 gene is cloned successfully and its prokaryotic expression is constructed。The results may facilitate understanding of the role of HPV16 E5 gene in development of squamous cell carcinoma。
