Penicillium is a genus of ascomycetous fungi that is part of the mycobiome of many species and is of major importance in the natural environment, in food spoilage, and in food and drug production.
Cellulase is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides:
An exoenzyme, or extracellular enzyme, is an enzyme that is secreted by a cell and functions outside that cell. Exoenzymes are produced by both prokaryotic and eukaryotic cells and have been shown to be a crucial component of many biological processes. Most often these enzymes are involved in the breakdown of larger macromolecules. The breakdown of these larger macromolecules is critical for allowing their constituents to pass through the cell membrane and enter into the cell. For humans and other complex organisms, this process is best characterized by the digestive system which breaks down solid food via exoenzymes. The small molecules, generated by the exoenzyme activity, enter into cells and are utilized for various cellular functions. Bacteria and fungi also produce exoenzymes to digest nutrients in their environment, and these organisms can be used to conduct laboratory assays to identify the presence and function of such exoenzymes. Some pathogenic species also use exoenzymes as virulence factors to assist in the spread of these disease-causing microorganisms. In addition to the integral roles in biological systems, different classes of microbial exoenzymes have been used by humans since pre-historic times for such diverse purposes as food production, biofuels, textile production and in the paper industry. Another important role that microbial exoenzymes serve is in the natural ecology and bioremediation of terrestrial and marine environments.
Endo-1,4-β-xylanase is any of a class of enzymes that degrade the linear polysaccharide xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls:
Penicillium roqueforti is a common saprotrophic fungus in the genus Penicillium. Widespread in nature, it can be isolated from soil, decaying organic matter, and plants.
Monoacylglycerol lipase is an enzyme that, in humans, is encoded by the MGLL gene. MAGL is a 33-kDa, membrane-associated member of the serine hydrolase superfamily and contains the classical GXSXG consensus sequence common to most serine hydrolases. The catalytic triad has been identified as Ser122, His269, and Asp239.
Candex is a dietary supplement manufactured by Pure Essence Laboratories. It is marketed as an enzymatic remedy to treat the yeast infection candida. Having the status of a dietary supplement, its efficiency has not been proven in scientifically controlled and peer-reviewed trials. Similar formulas exist, such as Candigest.
Pectin lyase is a polysaccharide enzyme with a complex structure that is present in plant cell walls. It has a significant role in pectin degradation and different biotechnological and industrial applications. It can be found in different organisms.
Penicillium chrysogenum is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, but it is mostly found in indoor environments, especially in damp or water-damaged buildings. It has been recognised as a species complex that includes P. notatum, P. meleagrinum, and P. cyaneofulvum. Molecular phylogeny has established that Alexander Fleming's first discovered penicillin producing strain is of a distinct species, P. rubens, and not of P. notatum. It has rarely been reported as a cause of human disease. It is the source of several β-lactam antibiotics, most significantly penicillin. Other secondary metabolites of P. chrysogenum include roquefortine C, meleagrin, chrysogine, 6-MSA YWA1/melanin, andrastatin A, fungisporin, secalonic acids, sorbicillin, and PR-toxin.
Extracellular enzymes or exoenzymes are synthesized inside the cell and then secreted outside the cell, where their function is to break down complex macromolecules into smaller units to be taken up by the cell for growth and assimilation. These enzymes degrade complex organic matter such as cellulose and hemicellulose into simple sugars that enzyme-producing organisms use as a source of carbon, energy, and nutrients. Grouped as hydrolases, lyases, oxidoreductases and transferases, these extracellular enzymes control soil enzyme activity through efficient degradation of biopolymers.
Thermotoga petrophila is a hyperthermophilic, anaerobic, non-spore-forming, rod-shaped, fermentative heterotroph, with type strain RKU-1T. T. petrophila was first discovered and isolated from an oil reservoir off of the coast of Japan and was deemed genetically distinct from its sister clades. Because these organism are found in deep, hot aquatic settings, they have become of great interest for biotechnology due to their enzymes functioning at high temperatures and pressures.
Penicillium brasilianum is a fungus species of the genus of Penicillium. Penicillium brasilianum produces the compounds isoroquefortine C, griseofulvin, ergosterol peroxide, 3β-hydroxy-(22E,24R)-ergosta-5,8,22-trien-7-one, cerevisterol, (22E,24R)-6β-methoxyergosta-7,22-diene-3β,5α-diol.
Penicillium decumbens is an anamorph species of the genus of Penicillium which occurs widespread in nature, mainly in subtropical and tropical soil but it also occur in food. Analysis have shown that Penicillium decumbens has antibiotic activity Penicillium decumbens produces the cyclopentenone cyclopenicillone
Penicillium freii is a psychrophilic species of the genus of Penicillium which produces xanthomegnin and patulin. Penicillium freii occurs in meat, meat products, barley and wheat
Penicillium janczewskii is an anamorph and filamentous species of the genus of Penicillium which was isolated from the rhizosphere of Vernonia herbacea. Penicillium janczewskii produces griseofulvin
Penicillium oxalicum is an anamorph species of the genus Penicillium which was isolated from rhizosphere soil of pearl millet. Penicillium oxalicum produces secalonic acid D, chitinase, oxalic acid, oxaline and β-N-acetylglucosaminidase and occurs widespread in food and tropical commodities. This fungus could be used against soilborne diseases like downy mildew of tomatoes
Penicillium pinophilum is a species of fungus in the genus Penicillium which was isolated from a radio set in Papua New Guinea. Penicillium pinophilum produces 3-O-methylfunicone and mycophenolic acid
