能防火的细菌为了预防矿井下甲烷着火爆炸,印度科学家培育了一种能吃甲烷的细菌。只要把含有这种细菌的水溶液洒在矿井中的每个角落,这种细菌在一周内就会吃掉15％的甲烷气体。经常喷洒这种水溶液,能避免矿井爆炸的发生。能造雨的细菌美国科学家发现,细菌可导致降雨。大量的细菌浮在海面 Fire-fighting bacteria In order to prevent the explosion of methane under the mine, Indian scientists have cultivated a bacteria that can eat methane. As long as the aqueous solution containing the bacteria is sprinkled in every corner of the mine, the bacteria will eat 15% of the methane gas within a week. Frequent spraying of this aqueous solution can prevent mine explosions. Bacteria that can make rain. American scientists have discovered that bacteria can cause rainfall. A lot of bacteria float on the surface of the sea
