A bacterium has been discovered that can substitute arsenic for phosphorus in fundamental life chemistry. Christopher Intagliata reports.
Life on earth requires six basic ingredients—carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. Those six elements are the building blocks for DNA and RNA, along with proteins and fats. Which means they're essential for life—as we know it. But it might be time to update that list. Because scientists have found a bacterium that can do without phosphorus—live on arsenic instead.
The researchers had a hunch a bug like this might exist, because arsenic has some chemical properties in common with phosphorus. So they collected mud from California's Mono Lake, where the waters are naturally salty, and laced with arsenic. Back in the lab, they cultured microbes from that mud. But instead of adding phosphorus to the cultures to help the bugs grow, they added varying levels of arsenic.
One bacterial strain continued to thrive. And tests confirmed that the organisms compensated for the lack of phosphorus by building their DNA with arsenic instead. The research appears in the journal Science. [Felisa Wolfe-Simon et al, A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus]
This is the first known life form that seems to be able to swap out one of life's fundamental building blocks with another element. So for astrobiologists hunting for life in space, don’t rule out places filled with poison.

这种细菌能长用砷代替磷

一种细菌被发现能够使用砷代替磷构成基础生命化学物质。Christopher Intagliata报道说。地球上的生物由六种基本物质组成：碳，氢，氮，氧，硫，磷。这六种元素以蛋白质和脂肪的形式构成了DNA和RNA。这就是说它们是生命的根本--诚如我们一直所知道的。但现在可能是更新这个认识的时候了。因为科学家发现了一种能够在无磷条件下生存的细菌--而以依赖砷代替。
科学家一直猜测这种可能性...

一种细菌被发现能够使用砷代替磷构成基础生命化学物质。Christopher Intagliata报道说。地球上的生物由六种基本物质组成：碳，氢，氮，氧，硫，磷。这六种元素以蛋白质和脂肪的形式构成了DNA和RNA。这就是说它们是生命的根本--诚如我们一直所知道的。但现在可能是更新这个认识的时候了。因为科学家发现了一种能够在无磷条件下生存的细菌--而以依赖砷代替。
科学家一直猜测这种可能性，因为砷和磷有着相似的化学性质。所以他们从加利福尼亚州的MONO河里搜集了一些泥土，这里的河水天然含盐，富有砷。回到实验室，他们将其中的微生物提取培养。用加入砷代替磷培养。
其中一支细菌群持续的繁衍。实验证实了它们使用了砷代替磷构成机体中DNA和RNA。这个研究发表在了《科学》杂志上。我日，我翻译到这里我才发现人家是喊翻译科学杂志上的那篇文章，太操蛋了。。。
