An efficient bacterial transformation system was described for the preparation of competent cells, plasmid preparation, and for the storage in bacterial stocks. 描述了一种改良的高效细菌感受态的制备和感受态细胞的保藏及细菌的转化方法。
This evaluation system can also be popularized to other management or policy-decision research. The resistant plasmids can be transferred to other bacterial through conjugation and transformation, it is very important in the outbreak of KB infection. 这种评价系统还可推广至其他管理及决策工作。耐药质粒可通过接合转移方式转移至其他细菌,这在多重耐药克雷伯氏菌暴发流行中具有重要意义。
The succession of bacterial physiological groups and substrate transformation in relation to the methane production in bio-gas fermentation 沼气发酵过程中主要微生物生理群的变化及物质转化对产气效率的影响
The resistant plasmids can be transferred to other bacterial through conjugation and transformation, it is very important in the outbreak of KB infection. 耐药质粒可通过接合转移方式转移至其他细菌,这在多重耐药克雷伯氏菌暴发流行中具有重要意义。
The bacterial infection induces and sustains an actively proliferating B-cell population through direct and indirect immunological stimulation. Moreover, the bacterial infection is involved in or promote the acquisition of genetic abnormalities and malignant transformation of reactive B-cells. 通过直接和间接免疫刺激,幽门螺杆菌的感染不仅引起并维持B细胞群的活跃增殖,还参与或促进异常基因的形成及反应性B细胞的恶变。
Discuss on the Bacterial Transformation and Leaching Mechanism of Chalcopyrite 黄铜矿细菌转化与浸出机理探讨
Bacterial transformation and amplification, to extract and purify enough two kinds of plasmids. 转化细菌,扩增、提取并纯化足量的两种质粒,经酶切及测序鉴定质粒正确。
However, conjugation is an effective pathway of genetic material transfer in bacterial strains whose background is unknown or for which there are no convenient or efficient methods of transformation or transduction. 但对于背景不很清楚,或没有转化或转导方法的菌株,接合转移是遗传物质转移的有效途径。
