Under standard conditions, from CH 4 to C 4 H 10 alkanes are gaseous; from C 5 H 12 to C 17 H 36 they are liquids; and after C 18 H 38 they are solids. As the boiling point of alkanes is primarily determined by weight, it should not be a surprise that the boiling point has almost a linear relationship with the size (molecular weight) of the.

Whereas degradation of hydrocarbons by oxygen-respiring microorganisms has been known for about a century, utilization of hydrocarbons under anoxic conditions has been investigated only during the past decade.
Diverse strains of anaerobic bacteria have been isolated that degrade toluene Cited by: The carbon chain length is crucially important in relation to HC utilization. Representatives of only a few species of microorganisms oxidize gaseous n-alkanes (up to C 4).
The most difficult to oxidize are short-chain liquid alkanes (C 5-C 10), and the most active growth is observed on C 13 –C Cited by: 7. In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is an acyclic saturated other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
Alkanes have the general chemical formula C n H 2n+ alkanes range in complexity from the simplest case of methane. Furthermore, utilization of n-alkanes from crude oil by sulfate-reducing bacteria has been demonstrated.
A moderately thermophilic sulfate-reducing bacterium (optimum around 60 Û& LVRODWHG RQ n-decane consumed n-alkanes from crude oil especially in the range from C8 to C11 . Furthermore, an enrichment culture exhibited sulfate-dependent.
It is important to note there are high molecular n-alkanes C 23, C 25, C 27, C 29, C 31 and C 33 in soil OM. Bacterial synthesis of n-alkanes could be accounted by decarboxylation with relatively high temperatures. However, this phenomenon doesn’t support by experiment.
In this work we studied, if n-alkanes with an odd number of. Methane monooxygenase from Methylobacterium sp.

Co-metabolic bioremediation is supposed to be an impressive and promising approach in the elimination technology of methyl tert-butyl ether (MTBE), which was found to be a common pollutant worldwide in the ground or underground water in recent years.
In metabolism of gaseous n-alkanes by bacteria book paper, bacterial strain DZ13 (which can co-metabolically degrade MTBE) was isolated and named as Pseudomonas sp. DZ13 based on the result Cited by: 2. During the Deepwater Horizon (DWH) oil spill in the Gulf of Mexico a deep-sea hydrocarbon plume developed resulting in a rapid succession of bacteria.
Colwellia eventually supplanted Oceanospirillales, which dominated the plume early in the spill. These successional changes may have resulted, in part, from the changing composition and abundance of hydrocarbons over time.
Colwellia. Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds [ 1 ]. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms [ 2 ]. When biodegradation is complete, the process is called "mineralization".

Smith, K. O'Reilly & M. Hyman. Fuel oxygenates, including ethers such as methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and tert-amyl methyl ether (TAME), as well as alcohols such as tert-butyl alcohol (TBA), tert-amyl alcohol, and ethanol, have been added to gasoline since the mid s, especially to improve air quality.
The major part of the contamination appeared to be related to leaking underground Cited by: 6. Figure shows the interrelationships among the physical, chemical, and biological processes that crude oil undergoes when introduced into the marine environment, subsequently weathers, and is then transported away from the source.
Processes involved in the weathering of crude oil include evaporation, emulsification, and dissolution, whereas. Alkane Derivatives. Almost an unlimited number of derivatives can be made from the alkanes since any hydrogen can be substituted by an alkyl group, a halide, etc.
If the substituent is an alkyl group, then the derivative will have the same empirical formula as a larger alkane, so the empirical formula for an organic compound is insufficient to identify it.
The detection of bacteria that oxidize n-alkanes having chain lengths of 2 to 8 carbon atoms, without any adaptation period, indicates the existence of short-chain hydrocarbons in the investigated soil samples, and thus can indicate the presence of oil accumulations in the subsurface.
In those areas in which both short-chain hydrocarbons and. Curry S, Ciuffetti L, Hyman M. Inhibition of growth of a Graphium sp.

Hydrogen isotope biogeochemistry is the scientific study of biological, geological, and chemical processes in the environment using the distribution and relative abundance of hydrogen are two stable isotopes of hydrogen, protium 1 H and deuterium 2 H, which vary in relative abundance on the order of hundreds of ratio between these two species can be considered the.
The sulfur cycle is the collection of processes by which sulfur moves between rocks, waterways and living systems. Such biogeochemical cycles are important in geology because they affect many minerals.
Biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or.
The most widely used supercritical fluid, however, is supercritical carbon dioxide (SCD), and while gaseous carbon dioxide is a hothouse gas that needs to be captured from flue gases and the atmosphere, the compacted form of SCD is a useful tool for order to use SCD intelligently, the properties of carbon dioxide as a chemical.
In this process, n-alkanes on heating with anhydrous aluminium chloride and hydrogen chloride get converted into branched chain alkanes. CRACKING OR PHYROLYSIS. It is a process of decomposing higher hydrocarbons into lower hydrocarbons with low boiling points by strong heating.
