Biotic and Abiotic Release of Inorganic Substances Exploited by Bacteria

摘要: The planet earth has an atmosphere, abundant liquid water, and extensive biota, including at least 0.5 million species of what are generally called plants some 1.5 animals. Although the length time microorganisms have colonized been present on is three- to fourfold longer than animals present, our knowledge microbial different times in biosphere poor. fossil record does show that microscopic forms life for 3.2 billion years and, from results biogeochemical studies, it evident made up bulk mass (Schopf et al, 1965). Hattori al. (1983) suggest oxidative-reductive reactions involving sulfur continental environments began about 2.2 x 109 ago, as did also a significant rise atmospheric C02 content. Microorganisms, with their biochemically diverse processes, interacted inorganic environment over sufficient period had pronounced influence organization (Cloud, 1983).
