地球上有多少细菌?科学家们对地球上的细菌数目进行了估算,他们发现,地球上的细菌数目约为5乘以10的30次方,这一数字远远大于宇宙的星星的数目,是世界人口的近10的21次方倍,数量之大让人咋舌。为了计算出世界细菌的数量,微生物学家惠特曼领导的研究小组列出从高层大气到深层海底的所有已知细菌的行为和属性,其中绝大部分细菌存在于土壤中。 细菌和病毒都属于微生物。细菌都是单细胞生物,即细菌都是一个细 How Many Bacteria Are on Earth? Scientists have estimated the number of bacteria on Earth, and they found that the number of bacteria on earth is about 5 times 10 by 30, a figure much larger than the number of stars in the universe. The world population of nearly 10 times 21 times times, the number of people astounded. To calculate the number of germs in the world, a team led by microbiologist Whitman lists the behavior and properties of all known bacteria from the upper atmosphere to the deep sea, most of which is found in the soil. Bacteria and viruses are microorganisms. Bacteria are single-celled organisms, that is, bacteria are a thin
