答：溶解氧就地处理是一种复杂的生物修复方法。它将本公司专利生物产品和增氧技术相结合，迅速地、稳定地对污染的土壤和地下水进行就地生物清除。 |
| 8. | Css is the one of the colonization factor antigens which is a protective antigen can cause immune reaction by the means taking orally . in this study , carrot was separately transformed with agrobacterium tumefacience strain lba4404 that contains ctb or ctb - cs3 fused gene in order to get oral diarrhea vaccine . this is a potent strategy to produce etec oral vaccine
本研究期望通过农杆菌转化系统将ctb (霍乱毒素b亚基，可作为佐剂和载体)基因和ctb - cs3融合基因分别转入胡萝卜植株，使ctb和ctb ? cs3融合基因稳定整合到胡萝卜基因组内，希望以此获得以胡萝卜为受体的etec口服疫苗，使服食者在进食的同时就可获得腹泻免疫。 |
| 9. | We determine the growth process and mutual relationship of three bacteria , i . e . photosynthetic bacteria , e . coli ki2 and etec 987p . relationship between pathogenic bacteria in water , aeromonas hydrophija , and phoiosynthetic bacteria was studied emphatically . the result showed that when inoculating quantity of phoiosynthetic bacteria was one fifth of that of aeromonas hydrophila , the growth of latter bacteria could be inhibited distinctly
其次，研究了混合生长体系的细菌色谱行为，实时对混合培养体系中每一种细菌的生长情况作出定量和定性的分析，确定了光合细菌、 e . colik12和etec987p三种细菌混合生长的过程及相互竞争与抑制的作用关系；针对水体中病原菌? ?嗜水气单胞菌，重点考察了它与光合细菌的作用关系，结果表明光合细菌的接种量为气单胞菌的1 5时，就能够对气单胞菌有明显的抑制效果。 |
| 10. | To dress the question if other virulence gene were present in this kind of strains , 152 of 436 irp2 - hybridized strains were re - confirmed and selected for this study . the virulence genes or putative virulence genes detected by pcr or hybridization include heat stable toxin ( st ) & heat labile toxin ( lt ) for enterotoxigenic e . coli ( etec ) , invasive plasmid antigen b ( ipab ) for enteroinvasive e . coli ( eiec ) , epec adherence factor ( eaf ) , epec secretion protein c ( espc ) for enteropathogenic e . coli ( epec ) , hemolysin ( hlya ) and shiga toxins ( sltl and slt2 ) for enterohaemorrhagic e . coli ( ehec ) and eaggec probe for entero - aggregative e . coli ( eaggec ) . the prra and yc73 genes of pathogenicity associated island ( pai ) of urepathogenic e . coli ( upec ) and " o " island 28 ( rtx 615 ) gene was also detected , the later was a newly discovered putative pathogenicity island in e . coli o157 : h7
为探讨携带小肠结肠炎耶尔森氏菌的hpi毒力岛的大肠杆菌是否具有其他已知的毒力基因，选取82株由原位杂交和pcr方法初筛irp2阳性的大肠杆菌菌株，进行在致泻性大肠杆菌的25个毒力基因的检测，包括肠产毒性大肠杆菌的热稳定毒素st和热不稳定毒素lt ，肠侵袭性大肠杆菌的侵袭蛋白b基因ipab ，肠致病性大肠杆菌的eaf 、 espc基因，肠出血性大肠杆菌的溶血素hly 、志贺毒素1 ( slt1 ) 、志贺毒素2 ( slt2 )基因，肠集聚性大肠杆菌的eaggec探针，以及在泌尿道致病性大肠杆菌和o157 ： h7大肠杆菌中新发现的毒力岛基因。 |
