Cladosporium Resinae
''Amorphotheca resinae'' is an ascomycete fungus of the family Amorphothecaceae which is known to thrive in environments containing alkanes (and water), like aviation fuel Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heating and road transport, and contain additives to enhanc ..., from which it derives its trivial name 'kerosene fungus'. As such it belongs to the heterogenous group of microbial contaminats of diesel fuel.

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amorphothecaceae
The Amorphothecaceae are a family of fungi in the division Ascomycota. This family can not yet be taxonomically classified in any of the ascomycetous classes and orders with any degree of certainty (incertae sedis). It contains the single genus ''Amorphotheca''. In nature, Amorphothecaceae exist under ''Taxus'' trees. The only known species within this family, '' Amorphotheca resinae'' (also known as ''Hormoconis resinae'' or ''Cladosporium resinae''), can live in tanks of diesel or jet fuel, consuming alkanes and traces of water Water (chemical formula ) is an Inorganic compound, inorganic, transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living ..., which can cause problems for airliners and boats.

Alkane
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In 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 . The alkanes range in complexity from the simplest case of methane (), where ''n'' = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane () or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (). The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms". However, some sources use the term to denote ''any'' saturated hydrocarbon, including those that are either monocyclic (i.e. the cycloalkanes) or ...

Aviation Fuel
Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heating and road transport, and contain additives to enhance or maintain properties important to fuel performance or handling. They are kerosene-based (JP-8 and Jet A-1) for gas turbine-powered aircraft. Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel. Specific energy (energy per unit mass) is an important criterion in selecting fuel for an aircraft. The much higher energy storage capability of hydrocarbon fuels compared to batteries has so far prevented electric aircraft using electric batteries as the main propulsion energy store becoming viabl ...

Microbial Contamination Of Diesel Fuel
Diesel bug is contamination of diesel fuel by microbes such as bacteria and fungi. Water can get into diesel fuel as a result of condensation, rainwater penetration or adsorption from the air — modern biodiesel is especially hygroscopic. The presence of water then encourages microbial growth which either occurs at the interface between the oil and water or on the tank walls, depending on whether the microbes need oxygen. Species which may grow in this way include: * bacteria — ''Clostridium''; '' Desulfotomaculum''; ''Desulfovibrio''; ''Flavobacterium''; ''Acidovorax facilis''; ''Pseudomonas''; ''Sarcina'' * fungi — ''Aspergillus''; '' Candida keroseneae''; ''Fusarium ''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil mi ...''; '' Hormoconis resinae'' Fuel companies agree that i ...

Fuel Polishing
Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel, red diesel and biodiesel. This fuel contamination, also known as 'fuel bugs', or 'diesel bugs', or 'so-called algae' build up over time in stored fuels if they aren't tested and treated on a regular basis. Fuel analysis should be undertaken before fuel polishing is commenced so that the exact contamination problem can be rectified with a targeted solution. A second fuel test should be performed after the fuel polishing has been completed to confirm the problem has been fixed. Sources of contamination * Water ** Dissolved Water ** Emulsified Water ** Free Water * Microbial Growth (AKA Diesel Bug) ** Bacteria ** Yeast ** Mold ** Bio-films * Solid Particle Contamination ** Rust ** Dirt ** Gums ** Wax ** Soot ** Organic Compounds Any and a ...

Candida Keroseneae
''Candida keroseneae'' is a species of yeast in the genus '' Candida'', family Saccharomycetaceae. Described as new to science in 2011, it was isolated from aviation fuel. Taxonomy The type strain of this yeast (IMI 395605T) was isolated from aircraft fuel (kerosene) sampled from a European aircraft. Later analysis demonstrated that the isolated strains were able to grow in liquid media containing 50% Jet A-1 aviation fuel. Molecular analysis was performed using the ribosomal RNA gene sequences of internal transcribed spacer regions in addition to the D1/D2 domains of the 26S nuclear ribosomal RNA gene. The two isolated strains clustered within the '' Candida membranifaciens'' clade, with '' C. tumulicola'' as the most closely related species. The specific epithet ''keroseneae'' is New Latin for kerosene, the substrate of the new species. Description The yeast cells, after growth on glucose-peptone-yeast extract broth culture for three days at , are egg-shaped to elongat ...
