Typically the green and purple sulfur bacteria live in that chemocline, enjoying the supply of H2S from below and sunlight from above.

绿菌紫菌通常会生活在变层中，同时享受下源源不绝充足阳光。

So long as their balance remains undisturbed, the oxygenated and hydrogen sulfide–saturated waters stay separated, and their interface, known as the chemocline, is stable.

直到达成平衡、不互相干扰，充氧海水饱和海水彼此分隔，而且两者间界面「变层」也是稳定。
