有一种细菌与地球上的其他任何生命都不同,它们靠最纯形式的能量——电子为生,吃的、呼吸的都是电子!它们无处不在。在地上插一根电极,输入电子,它们就会赶来。目前已知的食电细菌有两种:希瓦氏菌(图)和地杆菌,但最近美国科学家声称,他们培养出的食电细菌,与已知的两种食电细菌毫不相像。这意味着还有一个整体的微生物世界是我们从不知道的。从某种意义上说,它们就是异形。 There is a bacterium that is different from any other life on Earth. They depend on the purest forms of energy - electron living, eating, breathing, and electronically! They are everywhere. Put an electrode on the ground, enter the electron, they will come. Currently there are two kinds of food-borne bacteria: Shewanella (map) and Geobacter, but recently American scientists claimed that they cultivated food-borne bacteria that are not the same as the two known food-borne bacteria. This means that there is an entire microbial world that we never knew. In a sense, they are alien.
