Microorganisms Essay -- Biology, Bacteria, Biotechnology

Microorganisms play an important role in our spirit helps us to digest our food, decompose wastes and participate in various flavor staves. They ar diverse and have adapted to inhabit different environments including peak conditions, such as hot vents under the ocean to ice caps thence known as extremophiles. There be more microorganisms present in us than there are cells, and the various microorganisms are bacteria, viruses, fungi and protozoa. numerous people associate microorganisms as death and diseases causing agents also much compared to dirt. Although some microorganisms are responsible for causing diseases, most microorganisms original hosts are not the human body so are not pathogenic, just commensal. This essay will discuss the numerous beneficial microorganisms that carry egress processes in biotechnology, agriculture, industries and environment necessary to sustain life. First of all, essential uses of microorganisms are seen in the environment, as they play a vital role in numerous of the nutrient cycles. For instance, carbon fixation from the atmosphere during the carbon cycle by autotrophic bacteria, such as cyanobacteria synthesizes organic molecules for some other organisms and release oxygen for our consumption. In addition, microorganisms are vital participants of the food train since they act as decomposers breaking down dead organisms and organic materials and purgative minerals for uptake by living organisms and carbon dioxide back into the atmosphere for photosynthetic organisms. Microorganisms, known as methanogens, influence the carbon cycle by converting CO2 in their cells to methane and releasing it into atmosphere thus increasing methane concentration whereas methanothrophs devour methane from the atmosphere, lead... ...ate minerals from ores containing low-levels of minerals (Hofkin, 2010). Microorganisms have been beneficial to humans in the past too - the Weil-Felix streamlet for typhus. A patient infected w ith Rickettsia prosecute will have antibodies to this bacterial species circulating in their declivity which can bind to genus Proteus OX19, innocent soil bacterium. Physicians used to diagnose typhus by mixing patients blood serum with Proteus OX19, positive test for typhus is confirmed when Proteus OX19 is clumped together (Hofkin, 2010). Overall, microorganisms are vital for life on Earth and are more than disease causing agents. Few microorganisms are pathogenic, but many more has an important role in various ecological and industrial processes, maintaining human health and every day new discoveries are do that shows microorganisms are crucial for scientific advances to be made.
