她一向依靠媚兰，哪怕就在她依靠自己的时候，但是以前并没认识到。依据细菌外膜的类型，细菌可被分为革兰阴性与革兰阳性菌。

She had relied on Melanie , even as she had relied upon herself , and she had never known it . Depending on their type of outer membrane , bacteria can be considered either gram-negative or gram-positive .

在产ESBLs的情况下，细菌的外膜蛋白表达变化不是引起KPn对喹诺酮类耐药的主要原因。

In the case of producing ESBLs , OMP expression change was not the main resistant mechanism to quinolones . 5 .

内毒素（endotoxin）是存在于革兰氏阴性细菌胞壁外膜中的一种生物活性成分，在革兰氏阴性细菌感染的发病机制中起十分重要的作用，其主要毒性成分是脂多糖（lipopolysaccharideLPS）。

However , the relationship between endotoxemia and unpaired adaptive immunity is still in the dark . Lipopolysaccharide ( LPS ) is a toxic part of endotoxin which is a component of Gram negative bacterial cell wall .

孔蛋白是一种跨膜蛋白，主要存在于细菌质膜的外膜、线粒体和叶绿体的外膜上。

Porin is a transmembrane protein found in the outer membrane of mitochondria as well as in the outer membrane of gram positive bacteria .

putida5-x细胞外膜中的磷脂含量明显比其它报道的革兰氏阴性细菌的细胞外膜高，这可能是P.putida5-x细胞外膜具有较高Cu2+吸附容量的主要原因，并由此导致P。

The relatively high phospholipid content in the outer wall might result in its higher adsorption capacity to Cu ~ ( 2 + ), and leads to a higher adsorption capacity of the cell envelope of P.putida 5-x.

细菌对诺氟沙星耐药性的形成可能与细菌外膜通透性改变从而减少抗生素的摄入以及产生灭活酶或钝化酶修饰抗生素有关.本研究为进一步揭示嗜水气单胞菌外膜蛋白与耐药性相关性提供了理论依据。

The change of outer membrane permeability and the generation of inactive enzyme or modifying enzyme might be the reason that bacteria have the resistance to norfloxacin . The research was aim to know more about the correlation between A. hydrophila outer membrane protein and the resistance .

细菌内毒素（LPS）不仅是革兰阴性（G-）细菌细胞壁外膜的主要结构成分，而且是G-细菌感染的主要致病因子，与人类健康和疾病密切相关。

Bacterial endotoxins ( LPS ) are not only the major constituents of the outer membrane of Gram-negative ( G - ) bacteria , but also the toxic determinants for G - infection , which is closely related to human health and the development of diseases .
