Document Summary
Microorganisms, tiny titans of the earth: life forms too small to be seen by human eye, diverse in form/function, many single-celled, some form complex structures, some. In nature, cells typically live in microbial communities. In most: motility: many cells move through self-propulsion, differentiation: some microbes modify structures to form specialized cells. Intercellular communication: some microbes respond to other microbes: genetic exchange. In humans, 1-10 microbial cells per human cells. Improving food safety, preservation: dairy products, other food products, microorganisms and industry, biofilms: growth on submerged surfaces. Industrial microbiology: massive growth of naturally-occurring microbes to make low-cost products: biotechnology: genetically engineered microbes making high- value products in small amounts, production of biofuels, methane, ethanol, wastewater treatment, bioremediation: cleaning up pollutants. Light microscopy and the discovery of microorganisms: microbiology began with the microscope, robert hooke (1635-1703): first to describe microbes (micrographia in 1665)
