Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Single cell oil, also known as Microbial oil consists of the intracellular storage lipids, triacyglycerols. It is similar to vegetable oil , another biologically produced oil. They are produced by oleaginous microorganisms, which is the term for those bacteria, molds, algae and yeast, which can accumulate 20% to 80% lipids of their biomass. [ 1 ]
The oil crisis of 1970 triggered a great interest in active MEOR research in more than 15 countries. [1] From 1970 to 2000, basic MEOR research focused on microbial ecology and characterization of oil reservoirs. In 1983, Ivanov and colleagues developed the strata microbial activation technology.
Oil spills happen frequently at varying degrees along with all aspects of the petroleum supply chain, presenting a complex array of issues for both environmental and public health. [1] While traditional cleanup methods such as chemical or manual containment and removal often result in rapid results, bioremediation is less labor-intensive ...
Steer clear of products with bloated packaging at the store. It's a food safety issue—here's why. The post If You See Bloated Food Packaging, This Is What It Means appeared first on Reader's Digest.
Hydrocarbonoclastic bacteria have two fundamental characteristics: (1) specific membrane-bound dioxygenases [4] and (2) mechanisms for optimizing contact with water-insoluble hydrocarbons. [5] Microbial biodegradation occurs wherever oil contamination occurs. However, biodegradation rates are slow and as a result there are severe toxic effects ...
Some bacteria are able to utilize hydrogen formed during cathodic corrosion processes. Bacterial colonies and deposits can form concentration cells, causing and enhancing galvanic corrosion. [3] Bacterial corrosion may appear in form of pitting corrosion, for example in pipelines of the oil and gas industry. [4]
Biofilms can consist of a multitude of bacteria, fungi, and algae which are able to absorb, immobilize, and degrade many common pollutants found in wastewater.By harnessing a natural phenomenon, biofilm-mediated remediation is an environmentally friendly method for environmental cleanup. [3]
