Food Microbiology Fungal Spores: Highly Variable and Stress-Resistant Vehicles for Distribution and Spoilage
Food Microbiology 81 (2019) 2–11 Contents lists available at ScienceDirect Food Microbiology journal homepage: www.elsevier.com/locate/fm Fungal spores: Highly variable and stress-resistant vehicles for distribution and spoilage T Jan Dijksterhuis Westerdijk Fungal Biodiversity Institute, Uppsalalaan 8, 3584, Utrecht, the Netherlands ARTICLE INFO ABSTRACT Keywords: This review highlights the variability of fungal spores with respect to cell type, mode of formation and stress Food spoilage resistance. The function of spores is to disperse fungi to new areas and to get them through difficult periods. This Spores also makes them important vehicles for food contamination. Formation of spores is a complex process that is Conidia regulated by the cooperation of different transcription factors. The discussion of the biology of spore formation, Ascospores with the genus Aspergillus as an example, points to possible novel ways to eradicate fungal spore production in Nomenclature food. Fungi can produce different types of spores, sexual and asexually, within the same colony. The absence or Development Stress resistance presence of sexual spore formation has led to a dual nomenclature for fungi. Molecular techniques have led to a Heat-resistant fungi revision of this nomenclature. A number of fungal species form sexual spores, which are exceptionally stress- resistant and survive pasteurization and other treatments. A meta-analysis is provided of numerous D-values of heat-resistant ascospores generated during the years. The relevance of fungal spores for food microbiology has been discussed. 1. The fungal kingdom molecules, often called “secondary” metabolites, but with many pri- mary functions including communication or antagonism. However, Representatives of the fungal kingdom, although less overtly visible fungi can also be superb collaborators as is illustrated by their ability to in nature than plants and animals, are nevertheless present in all ha- form close associations with members of other kingdoms. -

Houbraken, [email protected]; J.C. Frisvad, [email protected] Abstract: Penicillium is a diverse genus occurring worldwide and its species play important roles as decomposers of organic materials and cause destructive rots in the food industry where they produce a wide range of mycotoxins. 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. -

<I>Byssochlamys</I> and Its <I>Paecilomyces</I&G
Persoonia 22, 2009: 14–27 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158509X418925 Polyphasic taxonomy of the heat resistant ascomycete genus Byssochlamys and its Paecilomyces anamorphs R.A. Samson1, J. Houbraken1, J. Varga1,2, J.C. Frisvad 3 Key words Abstract Byssochlamys and related Paecilomyces strains are often heat resistant and may produce mycotoxins in contaminated pasteurised foodstuffs. A comparative study of all Byssochlamys species was carried out using a Byssochlamys polyphasic approach to find characters that differentiate species and to establish accurate data on potential myco emodin toxin production by each species. Phylogenetic analysis of the ITS region, parts of the -tubulin and calmodulin Eurotiales β genes, macro and micromorphological examinations and analysis of extrolite profiles were applied. Phylogenetic extrolites analyses revealed that the genus Byssochlamys includes nine species, five of which form a teleomorph, i.e. B. fulva, heat resistance B. lagunculariae, B. nivea, B. spectabilis and B. zollerniae, while four are asexual, namely P. brunneolus, P. divari mycophenolic acid catus, P. formosus and P. saturatus. Among these, B. nivea produces the mycotoxins patulin and byssochlamic Paecilomyces acid and the immunosuppressant mycophenolic acid. Byssochlamys lagunculariae produces byssochlamic acid patulin and mycophenolic acid and thus chemically resembles B. nivea. Some strains of P. saturatus produce patulin and brefeldin A, while B. spectabilis (anamorph P. variotii s.s.) produces viriditoxin. Some micro- and macromorphologi- cal characters are valuable for identification purposes, including the shape and size of conidia and ascospores, presence and ornamentation of chlamydospores, growth rates on MEA and CYA and acid production on CREA. A dichotomous key is provided for species identification based on phenotypical characters. -
A Worldwide List of Endophytic Fungi with Notes on Ecology and Diversity

Mycosphere 10(1), 798–1079, Doi 10.5943/mycosphere/10/1/19 Abstract Endophytic fungi are symptomless internal inhabits of plant tissues. They are implicated in the production of antibiotic and other compounds of therapeutic importance. Ecologically they provide several benefits to plants, including protection from plant pathogens. There have been numerous studies on the biodiversity and ecology of endophytic fungi. Some taxa dominate and occur frequently when compared to others due to adaptations or capabilities to produce different primary and secondary metabolites. It is therefore of interest to examine different fungal species and major taxonomic groups to which these fungi belong for bioactive compound production. In the present paper a list of endophytes based on the available literature is reported. More than 800 genera have been reported worldwide. Dominant genera are Alternaria, Aspergillus, Colletotrichum, Fusarium, Penicillium, and Phoma. Most endophyte studies have been on angiosperms followed by gymnosperms. Among the different substrates, leaf endophytes have been studied and analyzed in more detail when compared to other parts. Most investigations are from Asian countries such as China, India, European countries such as Germany, Spain and the UK in addition to major contributions from Brazil and the USA. -
