Five ways in which microbes are beneficial
Microbes help in the body defense against other microorganisms. Microbes help to break down food in the human body, which is effective in maintaining a healthy weight. Another role of the roles of microbes invloves releasing various chemicals, which aid in increasing the body the metabolic activities in the body contamination (Cappuccino & Sherman, 2008).
. This, in turn, helps prevent gaining too much weight.
Microbes in the environment, where help to balance the ecosystem. These microorganisms help trigger decomposition of organic material. They are also responsible for fermentation and respiration, which are important processes for releasing energy. The decomposition is efficient when dealing with waste products and sewage treatment. Another benefit of microbes in our environment is in nitrogen fixation. This process involves the production of ammonia from nitrogen, which is used by plants. The microbes attach themselves to the plants maintaining the symbiotic association.
Louis Pasteur disproving spontaneous generation
Pasteur conducted experiments like the germ theory, which tried to prove that when various items were placed in the open air, would gather pathogens .This is contrary to those, which were placed away from the open environment. Louis Pasteur experiment to disapprove the theory, involved filtering air to gather its contents. He filtered the air using cotton, which he later used alcohol to collect the particles, which had been filtered. He later analyzed the extract and found microbes, which looked similar to other bacteria. This raised the question that if these types of microorganisms would be found in the air then, they could access any material and result in contamination (Cappuccino & Sherman, 2008).
Louis further conducted a second experiment where he used a flask and placed meat inside it. The
