The role of microorganisms in wastewater treatment helps to treat and purify wastewater and make it less harmful to the environment. Sewage treatment is based on the enhancement of naturally occurring human bacteria. One of the newer methods within bioremediation is to utilize the ability of bacteria to break down a number of chemical substances, such as chlorinated hydrocarbons and oil components. Microorganisms like fungi and bacteria are responsible for the spoilage of various foodstuffs, including bread. Bacteria, in particular, are the only living things that can fix nitrogen for use in plants. Environmental microbiology is the study of the composition and physiology of microbial communities in the environment. Environmental microbiology also includes the study of microorganisms that exist in artificial environments such as bioreactors. Household foods are produced by the family members for their own consumption. Some of the microorganisms are involved in food processing and preservation in household and industrial food production. While there are many different microbes used in sewage treatment, there are three well-known microbes that play an instrumental role in keeping sewage clean. The effects of microorganisms on their environment can be beneficial or harmful or inapparent with regard to human measure or observation.

Microbes are found everywhere, they are on and in our bodies, and in the food and water we drink and in the air we breathe. They also play a significant role in keeping a check on disease-causing microbes in our gut. When considering the impact of bacteria and other microbes on the earth it is important to grasp the concept of "MICROENVIRONMENTS" or "MICROHABITATS". Environmental microbiology also includes the study of microorganisms that exist in artificial environments such as … Microorganisms are present in all types of environmental sources like soil, air, water, animal body and plant etc. Besides, they also play a great role in ecological stability and the environment. Bioremediation can utilize naturally occurring bacteria or bacteria that have been added … Therefore, biodegradation is nature's way of recycling wastes, or breaking down organic matter into nutrients that can be used and reused by other organisms. Humans and microbes rely on these interactions to grow and stay healthy. CONCLUSION Based on the benefits of the use of microbes in controlling pests, the process helps in reducing environmental and public safety hazards of chemicals. The human host and its microbial flora constitute a complex ecosystem whose equilibrium serves as a … Microbes are everywhere in the biosphere, and their presence invariably affects the environment that they are growing in. The environment in this case means the soil, water, air and sediments covering the planet and can also include the animals and plants that inhabit these areas. Bacteria play an important role in the environment: Decomposition of Dead/Complex Organic Matter: ... Bacteria, and other micro-organisms are essentially important in the cycling of nutrients and energy, particularly in the breakdown of dead organic matter to make the resources locked up in things like dead trees available again to other living organisms. Different species of microbes live at different places in and on human body and these are adapted to the conditions in these places [2].

The different … Bacteria and fungi are required to maintain a healthy environment. The environment, in this case, means the soil, water, air and sediments covering the planet and can also include the animals and plants that inhabit these areas. There absorb nitrogen from the air and fix it in the soil. This definition is based on that of “biome,” the biotic and abiotic factors of given environments. Microorganisms play an important role in food industry. … The president-elect said he has chosen a team that prioritizes making clean energy jobs and environmental protection a cornerstone of his economic plans. There are many useful application of microbes in the food industry. There may be hundreds of millions to billions of microbes in a single gram of soil. Role of microorganisms in biodegradation of pollutants. and many microbes need specific environment provided by the human body to survive. Microorganism plays very important role in agriculture because the soil microbes (bacteria and fungi) are essential for decomposing organic matter and recycling old plant material. Introduction to aseptic techniques. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline), … They pose less threat to the … Similarly, the dough used to make bread is fermented using baker’s yeast (Saccharomyces cerevisiae).
