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.
Citrus production encompasses the production of citrus fruit, which are the highest-value fruit crop in terms of international trade. There are two main markets for citrus fruit:
Lasiodiplodia theobromae is a plant pathogen with a very wide host range. It causes rotting and dieback in most species it infects. It is a common post harvest fungus disease of citrus known as stem-end rot. It is a cause of bot canker of grapevine. It also infects Biancaea sappan, a species of flowering tree also known as Sappanwood.
Penicillium expansum is a psychrophilic blue mold that is common throughout the world in soil. It causes Blue Mold of apples, one of the most prevalent and economically damaging post-harvest diseases of apples.
Alternaria citri is a fungal plant pathogen that causes black rot in citrus plants.
Penicillium italicum is a fungal plant pathogen. It is a common post harvest disease commonly associated with citrus fruits.
Geotrichum candidum is a fungus which is a member of the human microbiome, notably associated with skin, sputum, and faeces where it occurs in 25–30% of specimens. It is common in soil and has been isolated from soil collected around the world, in all continents.
Rhizoctonia noxia is a species of fungus in the order Cantharellales. Basidiocarps are thin, effused, and web-like. The species is tropical to sub-tropical and is mainly known as a plant pathogen, the causative agent of "kole-roga" or black rot of coffee and various blights of citrus and other trees.
Michael Francis Madelin (1931–2007) was a British mycologist. He held research faculty positions at Imperial College, University of London, and the University of Bristol, and undertook pioneering research in conidial fungi and slime moulds, with specific reference to their physiology and ecology.
Penicillium adametzioides is an anamorph fungus species of the genus of Penicillium, which was isolated from decayed Grapes in Cheongsoo in Korea.
Penicillium dipodomyicola is a species of the genus of Penicillium which produces peniphenone A, peniphenone B, peniphenone C, peniphenone D, cyclopiazonic acid and patulin.
A species of the genus of Penicillium which causes Blue Mold of Garlic on Allium sativum L. The genus name is derived from the Latin root penicillum, meaning "painter's brush", and refers to the chains of conidia this fungus produces that resemble a broom.
Penicillium digitatum is a mesophilic fungus found in the soil of citrus-producing areas. It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould. In nature, this necrotrophic wound pathogen grows in filaments and reproduces asexually through the production of conidiophores and conidia. However, P. digitatum can also be cultivated in the laboratory setting. Alongside its pathogenic life cycle, P. digitatum is also involved in other human, animal and plant interactions and is currently being used in the production of immunologically based mycological detection assays for the food industry.
Trichothecium roseum is a fungus in the division Ascomycota first reported in 1809. It is characterized by its flat and granular colonies which are initially white and develop to be light pink in color. This fungus reproduces asexually through the formation of conidia with no known sexual state. Trichothecium roseum is distinctive from other species of the genus Trichothecium in its characteristic zigzag patterned chained conidia. It is found in various countries worldwide and can grow in a variety of habitats ranging from leaf litter to fruit crops. Trichothecium roseum produces a wide variety of secondary metabolites including mycotoxins, such as roseotoxins and trichothecenes, which can infect and spoil a variety of fruit crops. It can act as both a secondary and opportunistic pathogen by causing pink rot on various fruits and vegetables and thus has an economical impact on the farming industry. Secondary metabolites of T. roseum, specifically Trichothecinol A, are being investigated as potential anti-metastatic drugs. Several agents including harpin, silicon oxide, and sodium silicate are potential inhibitors of T. roseum growth on fruit crops. Trichothecium roseum is mainly a plant pathogen and has yet to show a significant impact on human health.
Neoscytalidium dimidiatum was first described in 1933 as Hendersonula toruloidea from diseased orchard trees in Egypt. Decades later, it was determined to be a causative agent of human dermatomycosis-like infections and foot infections predominantly in tropical areas; however the fungus is considered to be widespread. A newer name, Scytalidium dimidiatum, was applied to a synanamorph of Nattrassia mangiferae, otherwise known as Neofusicoccum mangiferae. Substantial confusion has arisen in the literature on this fungus resulting from the use of multiple different names including Torula dimidiata, Fusicoccum dimidiatum, Scytalidium dimidiatum, and Hendersonula toruloidea. Additionally, Scytalidium lignicola and Scytalidium lignicolum are often considered earlier names of N. dimidiatum.
Rhodotorula glutinis is the type species of the genus Rhodotorula, a basidiomycetous genus of pink yeasts which contains 370 species. Heterogeneity of the genus has made its classification difficult with five varieties having been recognized; however, as of 2011, all are considered to represent a single taxon. The fungus is a common colonist of animals, foods and environmental materials. It can cause opportunistic infections, notably blood infection in the setting of significant underlying disease. It has been used industrially in the production of carotenoid pigments and as a biocontrol agent for post-harvest spoilage diseases of fruits.
Penicillium commune is an indoor fungus belonging to the genus Penicillium. It is known as one of the most common fungi spoilage moulds on cheese. It also grows on and spoils other foods such as meat products and fat-containing products like nuts and margarine. Cyclopiazonic acid and regulovasine A and B are the most important mycotoxins produced by P. commune. The fungus is the only known species to be able to produce both penitrem A and roquefortine. Although this species does not produce penicillin, it has shown to have anti-pathogenic activity. There are no known plant, animal or human diseases caused by P. commune.
Lambertella corni-maris is a small ascomycete fungi. It grows in deciduous fruit areas, and causes postharvest Lambertella rot on apple fruits. The species also forms a mycoparasitism relationship with Monilinia fructigena. It is the type species of the genus Lambertella.
