It's a facultative anaerobe so that means it can undergo respiratory and fermentative metabolism.

它是兼性厌氧菌，这意味着它可经历呼吸和发酵代谢。

She's been charged with facilitating the abuse of underage girls for the former banker and sex offender, Jeffery Epstein.

她被控帮助前银行家兼性犯罪者杰弗瑞·爱泼斯坦虐待未成年女孩。

That makes the environment on the enamel surface favorable for facultative anaerobic bacteria, which can metabolize sugars with and without oxygen present.

这使牙釉质表面的环境有利于兼性厌氧菌生存；兼性厌氧菌即使在缺氧的情况下也可代谢糖类。

Select the advantages that a biped or facultative quadruped could gave.

选择双足动物或兼性四足动物可提供的优势。

At some point, the obligate quadrupeds like the sauropods would have had facultative bipedal ancestors.

在某个时，脚类动物这样的专性四足动物会有兼性双足动物的祖先。

Let's think of some of the advantages of being a biped or facultative quadruped.

让我们想想作为双足动物或兼性四足动物的一些优势。

Facultative roughly means optional, so a bear can optionally walk on two legs.

兼性致意思是可选的，所熊可选择用两条腿走路。

It's non-motile and doesn't form spores, and also, it's a facultative anaerobe, meaning that it can live with or without oxygen.

它没有运动能力，也不会形成孢子，同时，它也是兼性厌氧细菌，意味着它可在有氧或无氧的条件下生存。

Bears and all animals that can, but usually don't walk on two legs can be called facultative bipeds.

熊和所有可但通常不会用两条腿走路的动物都可称为兼性两足动物。

Remember a facultative quadruped is a biped that has the option to move on four limbs, just not all the time.

请记住，兼性四足动物是一种可用四肢移动的双足动物，只是不是一直都可。

It typically bounds at high speeds on two legs, but will walk on four legs when it is moving more slowly it would be considered a facultative quadruped.

它通常用两条腿高速跳跃，但当它移动得更慢时会用四条腿行走，这将被视为兼性四足动物。

On some TV shows and websites, it's been depicted as being facultatively bipedal, meaning that it could at times, carry itself on its hind legs, so it could run even faster on land.

在一些电视节目和网站上， 它被描绘成兼性双足动物，这意味着它有时可用后腿支撑自己，这样它在陆地上跑得更快。

It's a non-spore forming, aerobic, facultative intracellular, catalase and oxidase positive bacteria that is best visualized with silver stain and grows well on BCYE agar with cysteine and iron into grey-white colonies with a cut-glass appearance.

它是非芽孢、需氧、兼性细胞内寄生、氧化酶和过氧化氢酶阳性的细菌；最佳观察方式是银染色；在BCYE培养基供给半胱氨酸和铁的情况下生长良好，可形成雕花玻璃样的灰白色菌落。

Legionella pneumophila is non-spore forming, aerobic, which means it needs oxygen to survive, facultative intracellular, which means it can survive both inside and outside the cell, and oxidase and catalase positive, which means it produces both of these enzymes.

嗜肺军团菌是一种非芽孢好氧细菌，需要氧气才能存活，也是兼性细胞内寄生菌，即它在细胞内外均可生存，氧化酶和过氧化氢酶阳性，即它可产生这两种酶。

Alright, as a quick recap: Staphylococcus saprophyticus is round, gram-positive, facultative anaerobic, non-motile, non-spore forming, catalase positive, coagulase negative, urease positive, and novobiocin resistant bacterium, which is known to be part of the normal flora of the perineum.

得！来快速回顾一下：腐生葡萄球菌是一种圆形的、革兰染色阳性的、兼性厌氧细菌，无运动能力、不形成孢子，且过氧化氢酶阳性、凝固酶阴性、脲酶阳性，对新生霉素耐药，它是已知的会阴正常菌群的一部分。
