“…Extrolites : Most species produce sterigmatocystin (14/16) and precursors such as versicolorins, averufin, averufanin, and norsolorinic acid (( Jurjević et al., 2013 , Chen et al., 2016a , Jakšić Despot et al., 2017 ). Other extrolites from series Versicolores include aniduquinolones (2/14), brevianamides F, J, K, Q, R, T, U (1/14), calbistrins (3/14), deoxybrevianamides (2/14), isocoumarins (2/14), cyclopenols / viridicatols (2/14), emericellin / arugosins (1/14), shamixanthones (4/14), insulicolides (2/14), mangrovamides (1/14), psychrophilin E-H (1/14), sydowic acids (5/14), sydowinins (1/14), versicolamides (and notoamides, stephacidins) (7/14), versiols (2/14), violaceols (13/14), WIN64745 (1/14) ( Chen et al.…”

The Eurotiales is a relatively large order of Ascomycetes with members frequently having positive and negative impact on human activities. Species within this order gain attention from various research fields such as food, indoor and medical mycology and biotechnology. In this article we give an overview of families and genera present in the Eurotiales and introduce an updated subgeneric, sectional and series classification for Aspergillus and Penicillium . Finally, a comprehensive list of accepted species in the Eurotiales is given. The classification of the Eurotiales at family and genus level is traditionally based on phenotypic characters, and this classification has since been challenged using sequence-based approaches. Here, we re-evaluated the relationships between families and genera of the Eurotiales using a nine-gene sequence dataset. Based on this analysis, the new family Penicillaginaceae is introduced and four known families are accepted: Aspergillaceae , Elaphomycetaceae , Thermoascaceae and Trichocomaceae . The Eurotiales includes 28 genera: 15 genera are accommodated in the Aspergillaceae ( Aspergillago , Aspergillus , Evansstolkia , Hamigera , Leiothecium , Monascus , Penicilliopsis , Penicillium , Phialomyces , Pseudohamigera , Pseudopenicillium , Sclerocleista , Warcupiella , Xerochrysium and Xeromyces ), eight in the Trichocomaceae ( Acidotalaromyces , Ascospirella , Dendrosphaera , Rasamsonia , Sagenomella , Talaromyces , Thermomyces , Trichocoma ), two in the Thermoascaceae ( Paecilomyces , Thermoascus ) and one in the Penicillaginaceae ( Penicillago ). The classification of the Elaphomycetaceae was not part of this study, but according to literature two genera are present in this family ( Elaphomyces and Pseudotulostoma ). The use of an infrageneric classification system has a long tradition in Aspergillus and Penicillium . Most recent taxonomic studies focused on the sectional l...

“…Fungi are major producers of secondary metabolites with different biological activities and various chemical structures (Abo-Elmagd 2014). Until today, except for A. versicolor and A. sydowii, there is no thorough study on metabolic profiles for the Aspergillus species belonging to section Versicolores (Despot et al 2017). Moreover, to our knowledge, there are no published reports recorded the antimicrobial and the antioxidant activities of A. creber.…”

“…In 2012, Jurjevic et al revised the section Versi colores and accepted 13 species; among them, Aspergil lus creber was described for the first time as a new species. Currently, the section Versicolores comprises 17 distinct species (Despot et al 2017); among them, A. versicolor and A. sydowii are still the most commonly reported and studied species (Siqueira et al 2016). However, very few reports are available concerning the species A. creber and those reports were only concerned with contamination by A. creber and its ability to 3 310 produce STC.…”

Among the species belonging to the Aspergillus section Versicolores, Aspergillus creber has been poorly studied and still unexplored for its biological activities. The present study was undertaken to analyze A. creber extract and to evaluate its in vitro antimicrobial and antioxidant activities. UHPLC-MS/MS analysis of A. creber extract allowed the characterization of five known fungal metabolites including: asperlactone, emodin, sterigmatocystin, deoxybrevianamide E, and norsolorinic acid. The highest antimicrobial activity was displayed against Candida albicans, with a mean strongest inhibition zone of 20.6 ± 0.8 mm, followed by Gram-positive drug-resistant bacteria. The MIC values of A. creber extract varied from 0.325 mg/ml to 5 mg/ml. A. creber extract was shown a potent antioxidant activity and a high level of phenolic compounds by recording 89.28% scavenging effect for DPPH free radical, 92.93% in ABTS assay, and 85.76 mg gallic acid equivalents/g extract in Folin-Ciocalteu assay. To our knowledge, this is the first study concerning biological and chemical activities of A.creber species. Based on the obtained results, A.creber could be a promising source of natural antimicrobial and antioxidant compounds.

“…The official fungal DNA barcode applying ITS locus (Schoch et al 2012 ) has seemed to be insufficient for accurate identification of aspergilli and their sexual morphs, so, additional marker analyses were developed: calmodulin gene( CaM ), beta-tubuline ( BenA ) and RNA polymerase II second largest subunit ( RPB2 ) sequencing, along with extrolite spectrum data as well (Samson et al 2014 ; Frisvad 2015 ). Nowadays, 17 species are assigned to the Aspergillus section Versicolores:: A. amoenus, A. austroafricanus, A. creber, A. cvjetkovicii, A. fructus, A. griseoaurantiacus, A. hongkongensis, A. jensenii, A. pepii, A. protuberus, A. puulaauensis, A. subversicolor, A. sydowii, A. tabacinus, A. tennesseensis, A. venenatus and A. versicolor (Jakšić Despot et al 2017 ). According to the works by Chen et al ( 2016 ) and Hubka et al ( 2016 ), the section Versicolores was merged to the section Nidulantes as the A. versicolor clade, to maintain monophyly of Aspergillus .…”

Sterigmatocystin in foodstuffs and feed: aspects to consider

Sterigmatocystin (STC) is a possible human carcinogen (2B) according to International Agency for Research on Cancer classification and has been associated with immunotoxic and immunomodulatory activity, together with mutagenic effects. It might be found in numerous substrates, from foods and feeds to chronically damp building materials and indoor dust. Although European Food Safety Authority concluded that the exposure to STC to be of low concern for public health, reinforces the need of data concerning exposure of European citizens. Climate change can represent an increased risk of exposure to STC since it is a crucial factor for agro-ecosystem powering fungal colonisation and mycotoxin production This aspect can represent an increased risk for European countries with temperate climates and it was already reported by the scientific community.
