Microbiology Chapter 1 New VersionHow did the idea of spontaneous generation come about? - ANSWER.People came to believe that living organisms arise from nonliving matter because they would see flies coming out of manure, maggots coming out of dead animals, and microorganisms appearing in liquids after a day or two. What role does microbiology play in the biological control of pests? - ANSWER.Certain microorganisms cause diseases in insects. Microorganisms that kill insects can be effective biological control agents because they are specific for the pest and do not persist in the environment. What role does microbiology play in the recycling of elements? - ANSWER.Carbon, oxygen, nitrogen, sulfur, and phosphorus are required for all living organisms. Microorganisms convert these elements into forms that are useful for other organisms. Many bacteria decompose material and release carbon dioxide into the atmosphere, which plants use. Some bacteria can take nitrogen from the atmosphere and convert it into a form that plants and other microorganisms use. What role does microbiology play in normal microbiota? - ANSWER.Normal microbiota are microorganisms that are found in and on the human body. They do not usually cause disease and can be beneficial. What role does microbiology play in sewage treatment? - ANSWER.Organic matter in sewage is decomposed by bacteria into carbon dioxide, nitrates, phosphates, sulfate, and other inorganic compounds in a wastewater treatment plant. What role does microbiology play in human insulin production? - ANSWER.Recombinant DNA techniques have resulted in insertion of the gene for insulin production into bacteria. These bacteria can produce human insulin inexpensively. What role does microbiology play in vaccine production? - ANSWER.Microorganisms can be used as vaccines. Some microbes can be genetically modified to produce components of vaccines. What role does microbiology play in biofilms? - ANSWER.Biofilms are aggregated bacteria adhering to each other and to a solid surface.
