The genus Penicillium is large, with more than 354 species that are currently accepted 1. 3. All common species grow and sporulate well on synthetic or semi-synthetic media, and usually can be readily recognised at genus level. There are more than 200 known species and most of them grow quickly and spread easily from one place to another. It proved that the endophytic Penicillium species is producing distinguished secondary metabolites in association with medicinal plants. include mycotoxins, which are frequently found in contaminated food and feed products and pose a health risk to humans and animals. Penicillium. Some species produce toxins and may render food inedible or even dangerous. They are present in soil, […] So, Penicillium is a Genus (Kingdom, Phylum, Class, Order, Family, Genus, Species) and roqueforti, camemberti, album or glaucum are all species names. al., 2012). Penicillium spinulosum is psychrophilic, meaning that it is able to grow and reproduce at low temperature, and xerophile as it can germinate in decreased water activity environment (down to 0.8 Aw) by producing compatible solutes using enzyme systems. The genus Penicillium is commonly isolated from various terrestrial environments such as indoor environments, soil, and food, and is known to play … Different species of these fungi produce many types of secondary metabolites, ranging from the antibacterial drug penicillin to the antifungal drug griseofulvin, along with many compounds that are toxic to humans and animals. The fungus that most commonly colonizes salami is Penicillium nalgiovense, a mold that makes the white fluffiness we associated with salami. It was easy to assume that most species are generalists found wherever we care to make isolations. Where Penicillium Grows. And it can look quite diverse too! Reproduction. Actually, they are all sub-species of P. roqueforti. It was found that the majority of species within the dairy environment were in the genus Penicillium, and only a few of the samples were from Roquefort or Camembert cheeses, which suggests that the genera Penicillium is a source of major contamination in undesired cheese environments (Ropars et. 22 reported that the endophytic Penicillium species is involved and suppressing the growth of soil borne root rotting fungi M. phaseolina, R. solani, F. solani and F. oxysporum In vitro. For example, Penicillium italicum and Penicillium digitatum are common causes of rot of citrus fruits, while Penicillium expansum is known to spoil apples. Penicillium species are molds that colonize the surfaces of cheeses, salami, and other naturally aged fermented foods. In this paper, 15 species are described that originated from several … Description of Penicillium 2. This practise, however, obscured how Penicillium species might actually function in nature. Penicillin's mode of action is the beta lactum type of antibiotic. One species, Penicillium chrysogenum 9', is classified as a psychrotrophic microorganism. 36 37 Keywords: Penicillium nalgiovense, Penicillium olsonii, multilocus analysis, extrolites, salami 38 39 40 Highlights 41 A new species of Penicillium sect. However, P. spathulatum resembles P. brevicompactum and P. bialowiezense and shares the production of asperphenamate with all but one of the species in section Brevicompacta . The teleomorphs of Talaromyces species are loose and hyphal rather than stony like those of Penicillium species. Fig. Members of the genus produce penicillin, a molecule that is used as an antibiotic, which kills or stops the growth of certain kinds of bacteria inside the body.According to the Dictionary of the Fungi (10th edition, 2008), the widespread genus contains over 300 species. As the name suggests, some members of the Penicillium genus produce penicillin, a molecule which has long been used as a potent antibiotic; other species are used in cheesemaking. Vegetative Structure of Penicillium 3. The common occurrence of Penicillium species in food is a particular problem. Penicillium is a large genus, with 150 recognised species (Pitt, 1979a), of which 50 or more are of common occurrence (Pitt, 1988a). : New sections in Penicillium 301 Clade 6 P. fimorum Robsamsonia – CBS 140576 KT698888 KT698897 KT698907 Clade 6 P. fimorum Robsamsonia – DTO 159-F1 KT698889 KT698898 KT698908 Clade 6 P. glandicola Robsamsonia Penicillium CBS 498.75 KU896814 KU896838 KU904354 Clade 6 P. griseofulvum Robsamsonia Penicillium CBS 185.27 JF909942 KT900574 JN121449 (2005) found that this species was one of the best lipase producers among other fungi they studied in the arctic tundra. 6. penicillium species associated with fruit 21-24 24-25 25-27 28-31 6.1 importance of penicillium in the preharvest environment 6.2 importance of penicillium in the postharvest environment 6.3 peniciluum species associated with fruit surfaces 7. health and safety aspects of penicillium 8. control of penicillium species 9. conclusion 10. references The three genera are holophyletic in a cladistic sense and polythetic classes in an anagenetic or functional sense, and contain 344, 354, and 88 species, respectively. Classification and Examples Penicillium is a genus under phylum Ascomycota or Ascomycetes. are known as “technological” species. This species of mold is enormously diverse and is found not only in many distinct blue cheeses, but across the food world and the natural world. The name Penicillium comes from the resemblance of the conidiophore of the fungus to a paintbrush-- penicillus is the Latin word for paintbrush. Penicillium species colonize the surfaces of aged cheeses around the world either as starter cultures that are intentionally added during the cheese making process (5, 6) or as non-starter Penicillium species that enter cheese production facilities from natural fungal populations (7 – 9). Penicillium species are found in a variety of niches. It is particularly well known as the industrial producer of penicillin. Silva et al. Names like P. glaucum, P. stilton, etc. This is a bit of a half-truth. The mycophilic nature of many isolates of P. bialowiezense, and some of P. brevicompactum, suggests that observation of members of this group in indoor environments may predict extensive and longterm fungal colonization. Thus, this species produces extrolites found in both Penicillium subgenus Aspergilloides and subgenus Penicillium as these subgenera are presently understood (Houbraken & Samson, 2011). Aspergillus, Penicillium, and Talaromyces are among the most chemically inventive of all fungi, producing a wide array of secondary metabolites (exometabolites). Penicillium chrysogenum is a commonly found member of this genus in both natural and man made biotopes. In this case the two fungal species found growing in the dwelling were. Some species of Penicillium have an additional sexual state in … Penicillium brevicompactum and P. bialowiezense are two closely related species that are not easily distinguished by morphology or DNA sequencing. Penicillium is a genus of ascomycetous fungi of major importance in the natural environment as well as food and drug production. In another study two Penicillium species strains were isolated from coffee pulp. Penicillium species are common causes of spoilage of fruits, cheese, cold meats, old sandwiches, cereals and cereal products and a host of other agricultural and animal products. Penicillium is a large genus of fungi that are in the air, in soil and frequently on bread and produce. J. Houbraken et al. The name Penicillium comes from the word "brush"; this refers to the appearance of spores in Penicillium. This fungal diversity is important due to continued demand for biological sources of new enzymes and secondary Named after the spores’ likeness to a paintbrush (from the Latin penicillus), various species of Penicillium are found around the world, though they generally prefer cool to moderate climates. Penicillium, genus of blue or green mold fungi (kingdom Fungi) that exists as asexual forms (anamorphs, or deuteromycetes). Deacon et al. However, they prefer areas which are dark and damp. and Humicola grisea were major strongly cellulolytic microfungi from a grassland soil. The several kinds of penicillin synthesized by various species of the mold Penicillium may be divided into two classes: the naturally occurring penicillins (those formed during the process of mold fermentation) and the semisynthetic penicillins (those in which the structure of a chemical substance—6-aminopenicillanic acid—found in all penicillins is altered in various ways). According to Raper and Thom (1949), the genus includes 1 36 species, distributed throughout the world. The industrial production strain Wisconsin 54-1255 for which the genome has been published, was recently shown to be a member of the related species Penicillium rubens. (2006) also found in their study that Penicillium spp. with Trichoderma spp. Ascomycota - Wikipedia Penicillin is a secondary metabolite of certain species of Penicillium and is produced when growth of the fungus is inhibited by stress. [2] ADVERTISEMENTS: In this article we will discuss about:- 1. Description of Penicillium: Penicillium is a saprophytic fungus, commonly known as blue or green mold. Found on foodstuffs, leather, and fabrics, they are of economic importance in the production of Similarly, Penicillium was found most efficient at mineralizing spruce wood and was the only species that substantially mineralized spruce litter (Allison et al., 2009). laboratory. P. spinulosum is found worldwide and is most commonly isolated from soil. Moist conditions are favored among most fungi to avoid drying out. These strains had the ability to degrade almost 100% of caffeine in liquid medium . Penicillium species on cheeses and those producing antibiotics for treating bacterial infectious diseases are examples of ascomycetes. Bancerz et. P. glaucum is more commonly called P. expansum outside of cheese circles and is sometimes used to describe the light green mould found in Gorgonzola. Stachybotrys chartarum colonies on PDA for 14 days. Penicillium is a member of the deuteromycetes, fungi with no known sexual state. Typical Areas Found. al. Penicillin is one of the most important antibiotics extracted from Penicillium sp. have found several Penicillium species at four stages of maturation and processing of coffee cherries of Coffee arabica in Brazil. Those species for which the sexual phase is known are placed in the Eurotiales. Finally, there is one other important respiratory disease caused by the inhalation of Penicillium species conidia. P. chrysogenum and P. cyclopium. Penicillium species are naturally found and colonize in soil, degrading vegetation, damp and leather objects of the tropical and sub tropical regions of the world in that particular environment. It is a good practice to discard foods showing the development of any mould. Penicillium can be found at various places such as soil, air, on decaying food, etc. This blue or blue-green colored mold is one of the most common kinds of mold found in ordinary homes.
