What Are The Examples Of Helpful Bacteria?
- Rhizobium. It is a bacteria found in the soil which supplies ammonia to the plants, which is crucial for the growth of the plants.
- Streptomyces.
- Lactobacillus Acidophilus.

What bioremediation means?
Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminants in the soil and other environments.
Why is bioremediation bad?
Disadvantages of Bioremediation If the process is not controlled it is possible the organic contaminants may not be broken down fully resulting in toxic by-products that could be more mobile than the initial contamination. If an ex-situ process is used, controlling volatile organic compounds (VOCs) may be difficult.
What is called bioremediation?
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments.
Which microorganisms are useful to us?
Microorganisms and its uses
- Production of dairy products: Bacteria are the key players here.
- Bread Baking: A species of Streptococcus is added to the dough before making bread to bring about the required fermentation.
- Alcoholic Drinks:
- Organic acids:
- Enzymes:
- Steroid production:
- Help in sewage treatment:
- Used as insecticides:
What are the impacts of microorganisms to other living things?
The most significant effect of the microorganisms on earth is their ability to recycle the primary elements that make up all living systems, especially carbon (C), oxygen (O) and nitrogen (N). These elements occur in different molecular forms that must be shared among all types of life.
Why are microorganisms so important?
Micro-organisms and their activities are vitally important to virtually all processes on Earth. These microbes play key roles in nutrient cycling, biodegradation/biodeterioration, climate change, food spoilage, the cause and control of disease, and biotechnology.
What are the 2 types of bioremediation?
Some of the most common types of bioremediation are microbial bioremediation, phytoremediation, and mycoremediation.
Which organism is most important in biodegradation?
Several microorganisms, including fungi, bacteria and yeasts are involved in biodegradation process. Algae and protozoa reports are scanty regarding their involvement in biodegradation [5]. Biodegradation processes vary greatly, but frequently the final product of the degradation is carbon dioxide [6].
How can we purify polluted river water?
River water, polluted by the dumping of untreated urban sewage, has been used for irrigation and agricultural crop production in some countries such as India [20]. The quality of river water naturally improves by self-purification processes through dilution, sedimentation and biological processes.
How is bioremediation helpful?
The major benefits of bioremediation are: Completely natural process with almost no harmful side effects. Carried out in situ for most applications with no dangerous transport. Quick turnaround time to make soil and water useful.
What organisms are used in bioremediation?
Bioremediators are biological agents used for bioremediation in order to clean up contaminated sites. Bacteria, archaea and fungi are typical prime bioremediators [2].
How has bioremediation been used?
The first commercial in situ bioremediation system was installed in 1972 to cleanup a Sun Oil pipeline spill in Ambler, Pennsylvania. Since 1972, bioremediation has become well developed as a means of cleaning up spills of gasoline, diesel, and other easily degraded petroleum products.
What is the role of bacteria and fungi in cleaning the environment?
Genetic analysis shows microbial interactions help fast-growing trees break down petrochemical pollutants in soil. Highly complex interactions among roots, fungi and bacteria underlie the ability of some trees to clean polluted land, according to a novel study by bioinformatics and plant-biology experts.
How does Microbiology relate to environmental health?
Environmental health microbiology is a branch of public health concerned with the environmental occurrence of disease-causing microbes and with creating health-supportive environments. Microbes of a zoonotic nature or microbes transmitted through water, soil, or environmental surfaces are of special interest.
What are the five harmful effects of microorganisms?
Harmful effects of microorganisms:
- Bacteria: Causes various diseases such as typhoid, diarrhea, and cholera.
- Fungi: Causes a large number of diseases in plants and in animals such as rust diseases in plants, fruit rot in apple, red rot in sugar cane and ring worm disease in human beings.
What is bioremediation process?
Bioremediation process is degrading, removing, changing, immobilizing, or detoxifying various chemicals and physical pollutants from the environment through the activity of bacteria, fungi, algae and plants.
What is microbiology and its importance?
Microbiology is the study of microorganisms: living organisms that are too small to be observed by the naked eye. The discipline focuses on the structure, function, and classification of these organisms and looks for ways to exploit and control their activities.
How decomposers help in cleaning the environment?
Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals. So, decomposers can recycle dead plants and animals and help keep the flow of nutrients available in the environment.
What is bioremediation give an example?
Bioremediation companies that specialize in soil and groundwater use microbes that feed on the hazardous substances for energy, which results in the breakdown of the targeted contaminant. Examples include junkyards, industrial spills, land development, fertilizer use, and more.
How do microorganisms harm humans?
Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease.
Why is environmental microbiology important?
Environmental microbiology is the study of the composition and physiology of microbial communities in the environment. Molecular biology has revolutionized the study of microorganisms in the environment and improved our understanding of the composition, phylogeny, and physiology of microbial communities.
