Preface When I was in El-Badrashen primary school (1944-1950) I used to visit my classmates living in the nearby villages of Memphis and Sakkara. There, I heard from girls and women that they liked to eat mouldy bread because they thought it rendered their hairs smooth and shiny. When, I searched the internet using the key words Ancient Egyptians and Penicillium. Surprisingly, I found several sites indicating that the Egyptian polymath, Imhoteb, was one of the first physicians or doctors known to history, who prescribed mouldy bread for healing wounds, i.e. he predicted the presence of antibiotics in moulds 4700 years ago.

Introduction Penicillium is a well known cosmopolitan genus of moulds that comprises more than 350 species playing various roles in natural ecosystems, agriculture and biotechnology. They have double faces, a good and beneficial one and a bad and economically destructive one. Examples of the beneficial roles are: Penicillium chrysogenum produces the antibacterial antibiotic penicillin, Penicillium griseofulvum produces the antifungal antibiotic griseofulvin, several Penicillium species produce anti-cancer substances such as Penicillium albocoremium (Andrastin A), P. decumbens (Bredenin). Penicillium roqueforti is used for the production of Roquefort cheese and Penicillium camemberti is used for the production of Camembert cheese. Several Penicillium species produce enzymes that are used in industry, e.g. cellulases and xylanases produced by Penicillium species have broad applications in food and feed, the textile industry, and the pulp and paper industries. Penicillium species are also used for biodegradation of oil and can be used in restoring the ecosystem when contaminated by oil. Peroxidase enzyme of Penicillium species have potential biodegradable activities that degrade Amaranth dye, Orange G, heterocyclic dyes like, Azure B and Lip dye. Morepver, some species function as decomposers of dead materials and can be used in recycling of waste products. Recently, Penicillium species, such as P. aurantiogriseum, P. citrinum, and P. waksmanii, are used for the eco-friendly biosynthesis of gold nanoparticles from a solution of AuCl. Gold nanoparticles are formed fairly uniform with spherical shape with the Z-average diameter of 153.3 nm, 172 nm and 160.1 nm for the 3 species, respectively. On the other hand, some species are known to cause postharvest diseases, e.g. Penicillium expansum is one of the most prevalent post-harvest rots that infects apples. Although it is a major economic problem in apples, this plant pathogen can be isolated from a wide host range, including pears, strawberries, tomatoes, corn, and rice. This mould also produces the carcinogenic metabolite patulin, a neurotoxin that is harmful in apple juice and apple products. patulin in food products is a health concern because many are consumed by young children. In addition, a second secondary metabolite citrinin is produced as well. Mould growth on citrus fruits during storage is a continuing problem that results in economic loss. Although several fungal species have been reported to be involved in the spoilage of citrus products, Penicillium digitatum (green mold) and Penicillium italicum (blue mold) are the primary organisms involved. Penicillium is one of the first fungi to grow on water-damaged materials and has been implicated in causing allergic reactions, hypersensitivity pneumonitis, and a variety of severe lung complications. It may cause sarcoidosis, fibrosis, or allergic alveolitis in susceptible individuals, or patients who have been exposed over long periods of time, depending on the strain. P. oxalicum has also been reported to cause genital infection of water buffalo. 4 2.

  • Penicillium Arizonense, a New, Genome Sequenced Fungal Species
    www.nature.com/scientificreports OPEN Penicillium arizonense, a new, genome sequenced fungal species, reveals a high chemical diversity in Received: 07 June 2016 Accepted: 26 September 2016 secreted metabolites Published: 14 October 2016 Sietske Grijseels1,*, Jens Christian Nielsen2,*, Milica Randelovic1, Jens Nielsen2,3, Kristian Fog Nielsen1, Mhairi Workman1 & Jens Christian Frisvad1 A new soil-borne species belonging to the Penicillium section Canescentia is described, Penicillium arizonense sp. nov. (type strain CBS 141311T = IBT 12289T). The genome was sequenced and assembled into 33.7 Mb containing 12,502 predicted genes. A phylogenetic assessment based on marker genes confirmed the grouping ofP. arizonense within section Canescentia. Compared to related species, P. arizonense proved to encode a high number of proteins involved in carbohydrate metabolism, in particular hemicellulases. Mining the genome for genes involved in secondary metabolite biosynthesis resulted in the identification of 62 putative biosynthetic gene clusters. Extracts ofP. arizonense were analysed for secondary metabolites and austalides, pyripyropenes, tryptoquivalines, fumagillin, pseurotin A, curvulinic acid and xanthoepocin were detected. A comparative analysis against known pathways enabled the proposal of biosynthetic gene clusters in P. arizonense responsible for the synthesis of all detected compounds except curvulinic acid. The capacity to produce biomass degrading enzymes and the identification of a high chemical diversity in secreted bioactive secondary metabolites, offers a broad range of potential industrial applications for the new speciesP. arizonense. The description and availability of the genome sequence of P. arizonense, further provides the basis for biotechnological exploitation of this species. Penicillia are important cell factories for the production of antibiotics and enzymes, and several species of the genus also play a central role in the production of fermented food products such as cheese and meat.

Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista, Eladia, Eupenicillium, Torulomyces and Thysanophora, which together comprise a large monophyletic clade.
