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 ]
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 ...
Petroleum microbiology is a branch of microbiology that deals with the study of microorganisms that can metabolize or alter crude or refined petroleum products.These microorganisms, also called hydrocarbonoclastic microorganisms, can degrade hydrocarbons and, include a wide distribution of bacteria, methanogenic archaea, and some fungi.
Bioremediation is not specific to metals. In 2010 there was a massive oil spill in the Gulf of Mexico. Populations of bacteria and archaea were used to rejuvenate the coast after the oil spill. These microorganisms over time have developed metabolic networks that can utilize hydrocarbons such as oil and petroleum as a source of carbon and ...
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 ...
All petroleum products are derived from crude oil whose major constituents are hydrocarbons, that can be separated into four fractions: saturated, aromatic, resin and asphaltene fractions. The susceptibility of hydrocarbons to microbial degradation can be generally ranked as follows: linear alkanes branched alkanes > small aromatics > cyclic ...
The treatment of human lice is the removal of head lice parasites from human hair. It has been debated and studied for centuries. It has been debated and studied for centuries. However, the number of cases of human louse infestations (or pediculosis ) has increased worldwide since the mid-1960s, reaching hundreds of millions annually. [ 1 ]
Shaving was the primary form of hair removal until reports in 1983 showed that it may lead to an increased risk of infection. [33] Clippers are now the recommended pre-surgical hair removal method. [34] [35] A 2021 systematic review brought together evidence on different techniques for hair removal before surgery. This involved 25 studies with ...
