生活在美国黄石国家公园喷泉中的微生物族群很早就引起了科学家的兴趣,黄石公园地热喷泉的环境非常特别,那里的温度高达70℃,在这样的环境中,光合作用是不能进行的。那么这些微生物是以什么为食物的呢?长期以来的流行观点是,这些生活在高热极限环境中的微小生命体吃的是硫磺。
The community of micro-organisms living in the Yellowstone National Park fountain has long attracted the interest of scientists. The environment of the Geothermal Geyser at Huangshi Park is very special. The temperature there is as high as 70°C. In such an environment, photosynthesis cannot be carried out. So what do these microbes eat? It has long been the prevailing view that these tiny living organisms living in extreme heat extremes eat sulfur.
