Penicillium chrysogenum (formerly known as Penicillium notatum) 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, [1] but it is mostly found in indoor environments, especially in damp or water-damaged buildings. [2]
[10] [11] The Seventeenth International Botanical Congress held in Vienna, Austria, in 2005 adopted the name P. chrysogenum as the conserved name (nomen conservandum). [12] Whole genome sequence and phylogenetic analysis, particularly using β-tubulin sequences, in 2011 showed that P. notatum is P. rubens, and that P. chrysogenum is a different ...
Penicillium (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm /) 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.
Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation [2] and then purified. [ 3 ] [ 4 ] A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G ( intramuscular or intravenous use ) and penicillin V (given by mouth).
But Thom adopted and popularised the use of P. chrysogenum. [18] In addition to P. notatum, newly discovered species such as P. meleagrinum and P. cyaneofulvum were recognised as members of P. chrysogenum in 1977. [19] To resolve the confusion, the Seventeenth International Botanical Congress held in Vienna, Austria, in 2005 formally adopted ...
These diagrams are called natural keys or synopses and are not used for identifying specimens. In contrast, an artificial identification key is a tool that utilizes characters that are the easiest to observe and most practical for arriving at an identity. [2]: 7 [6]: 225 Identification keys can be divided into two main types.
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
