説明

<p>Observation of modern and fossils specimens using electron microscopy have shown the evolutionary processes of biomineralization in various microorganisms under the primitive Earth and the present environments. The primitive Earth consisted of an oxygen-free atmosphere and rocky surfaces rich in dissolved iron, manganese, and sulfur ions, in as much as the present hot springs with colorful short-lived microbial mats containing heat-resistant enzymes. Clay minerals are the most likely candidates responsible for affecting the synthetic reaction of microorganisms as catalyzes in the Earth’s surfaces. Presently, advances in biotechnology and biomedicine have made bacteria indispensible for industrial and medical forces. Undoubtedly, humans have become the most significant agent modifying the Earth’s surface. Microorganisms look after the humans, and they will help human life in the planet Earth, such as mining geological resources, executing bioremediation to treat water pollution, and using pollutant-degrading bacteria in cleaning up soils.</p>
