Which microorganism is used in wastewater treatment and use of microorganisms and plants to remove or neutralize pollutants in soil or water?
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria to decontaminate affected areas. It is used in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Furthermore, anaerobic bacteria are an important element in the wastewater treatment processes. They are responsible for methane fermentation of sewage sludge, facilitating decomposition of macromolecular organic matter into simpler compounds.
Generally in wastewater treatment the most important functional group of bacteria and archaea are heterotrophs oxidizing organic matter and nitrifyers oxidizing ammonia.
I agree with Dr Henrik Rasmus Andersen that an anaerobic bacteria are an important element in the wastewater treatment processes. They are responsible for methane fermentation of sewage sludge, facilitating decomposition of macromolecular organic matter into simpler compounds. Degrading contaminants present in the soil, wastewater, or industrial sludge by biological means. Microorganisms can take part in this process, although plant-assisted bioremediation is often termed as phytoremediation. Bioremediation is a technique used to remove environmental contaminants from the ecosystem. It utilizes the biological mechanisms inherent in microbes and plants to eradicate hazardous pollutants and restore the ecosystem to its original condition. Phytoremediation is a promising technology that uses plants and their associated microbes to clean up contaminants from the environment. In recent years, phytoremediation assisted by plant growth-promoting bacteria (PGPB) has been highly touted for cleaning up toxic metals from soil. Aerobic bacteria are predominant in biological wastewater treatment processes such as activated sludge and trickling filters and other biological processes that utilize free oxygen for their biochemistry. The secondary stage of treatment removes about 85 percent of the organic matter in sewage by making use of the bacteria in it. The principal secondary treatment techniques used in secondary treatment are the trickling filter and the activated sludge process.
Palm oil effluents use various bacteria for various parts of the process. Where there is lean COD, aerobic bacteria are used. When the COD is high, then anaerobic bacteria are used.
Environmental remediation deals with the removal of contaminants or pollution from soil, groundwater, sediment, or surface water or cleaning up after an oil spill. Water disinfection refers to the process of removal, deactivation, and/or killing of pathogenic microorganisms in potable water. Phytoremediation basically refers to the use of plants and associated soil microbes to reduce the concentrations or toxic effects of contaminants in the environment. Phytoremediation is widely accepted as a cost-effective environmental restoration technology. Bioremediation is the process of using microorganisms such as bacteria, algae, fungi, and plants to break down, change, remove, immobilize, or detoxify various physical and chemical pollutants in the environment. Furthermore, anaerobic bacteria are an important element in the wastewater treatment processes. They are responsible for methane fermentation of sewage sludge, facilitating decomposition of macromolecular organic matter into simpler compounds. Aerobic, Anaerobic and Facultative Bacteria and bacteria account for 95% of the microorganisms in wastewater. They are single-celled microorganisms that are classified based on their response to oxygen.
