These sediments were anoxic, or poor in oxygen, and they were also full of hydrogen sulfide.

这些沉积物是或含量很低，并且它们充满了硫化氢。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.

同样，在这种情况下，它将沉积物中硫化氢还原剂与靠近表面化剂连接起。

As a result, the ocean becomes oxygen poor, or hypoxic, or even anoxic, where there's no oxygen left.

结果，海洋变得，或，甚，那里没有气。

Two years ago in a former anoxic silt deposit I have found animal bones from between 275 and 1300 AD.

两前，我在一个以前淤泥沉积物中发现了公元 275 1300 之间动物骨头。

The conditions are often swampy or anoxic, so no oxygen, and this prevents rotting and predation by other animals and scavengers.

条件通常是沼泽或，所以没有气，这可以防止其他动物和清道夫腐烂和捕食。

To live in this environment, some bacteria have adapted to produce enzymes that still function at very high temperatures, and others even respire nitrogen instead of oxygen so they can tolerate anoxic conditions.

为了在这种环境中生存，一些细菌已经适应了产生在高温下仍能起作用酶，还有一些细菌甚呼吸氮气而不是气，这样它们就能忍受条件。
