Chapter 11 Marine Fungi Associated with Antarctic Macroalgae
Chapter 11 Marine Fungi Associated with Antarctic Macroalgae Mayara B. Ogaki, Maria T. de Paula, Daniele Ruas, Franciane M. Pellizzari, César X. García-Laviña, and Luiz H. Rosa Abstract Fungi are well known for their important roles in terrestrial ecosystems, but filamentous and yeast forms are also active components of microbial communi- ties from marine ecosystems. Marine fungi are particularly abundant and relevant in coastal systems where they can be found in association with large organic substrata, like seaweeds. Antarctica is a rather unexplored region of the planet that is being influenced by strong and rapid climate change. In the past decade, several efforts have been made to get a thorough inventory of marine fungi from different environ- ments, with a particular emphasis on those associated with the large communities of seaweeds that abound in littoral and infralittoral ecosystems. The algicolous fungal communities obtained were characterized by a few dominant species and a large number of singletons, as well as a balance among endemic, indigenous, and cold- adapted cosmopolitan species. The long-term monitoring of this balance and the dynamics of richness, dominance, and distributional patterns of these algicolous fungal communities is proposed to understand and model the influence of climate change on the maritime Antarctic biota. In addition, several fungal isolates from marine Antarctic environments have shown great potential as producers of bioactive natural products and enzymes and may represent attractive sources of biotechno- logical products.

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.

Evidence Brief: Foraged Mushroom Consumption in Ontario Wild Mushrooms Are Found in Ontario’S Farmers’ Markets
EVIDENCE BRIEF Foraged Mushroom Consumption in Ontario November 2019 Key Messages Wild mushrooms are widespread in Ontario, and are harvested by individual hobbyists and commercial enterprises for public consumption. Many species are poisonous. Health effects of such species can range from mild to severe, including death. However, serious poisonings are rare. There are no simple tests to determine if a mushroom is poisonous. Safe consumption of wild mushrooms and other wild foods requires they be correctly identified by knowledgeable harvesters. Over a thousand calls were made to the Ontario Poison Centre (OPC) over a recent 5-year period that were mushroom-related, with at least 90 cases resulting in hospital admission. There are no reported cases of poisoning linked to commercial foraging. However, currently there is no mechanism for licensing or accrediting wild mushroom foragers. Evidence Brief: Foraged Mushroom Consumption in Ontario Wild mushrooms are found in Ontario’s farmers’ markets. Certain farmers’ market food vendors are exempt from the Food Premises Regulation. However, assessments and inspections may be carried out to ensure compliance with the Health Protection and Promotion Act. Issue and Research Question Foraging of wild mushrooms occurs in diverse communities, including some within Ontario. 1-3 Foraged mushrooms may be sold in farmers’ markets, grocery stores, health food stores, restaurants, and online. There are reported cases of adverse health outcomes from consuming foraged mushrooms.1 Public health units in Ontario have requested advice from Public Health Ontario in response to concerns of potential adverse health effects from consumption of wild foraged mushrooms being sold in their regions. -

Phylogeny of Penicillium and the Segregation of Trichocomaceae Into Three Families

Houbraken1,2 and R.A. Samson1 1CBS-KNAW Fungal Biodiversity Centre, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands; 2Microbiology, Department of Biology, Utrecht University, Padualaan 8, 3584 CH Utrecht, The Netherlands. *Correspondence: Jos Houbraken, [email protected] Abstract: Species of Trichocomaceae occur commonly and are important to both industry and medicine. They are associated with food spoilage and mycotoxin production and can occur in the indoor environment, causing health hazards by the formation of β-glucans, mycotoxins and surface proteins. Some species are opportunistic pathogens, while others are exploited in biotechnology for the production of enzymes, antibiotics and other products. Penicillium belongs phylogenetically to Trichocomaceae and more than 250 species are currently accepted in this genus. In this study, we investigated the relationship of Penicillium to other genera of Trichocomaceae and studied in detail the phylogeny of the genus itself. In order to study these relationships, partial RPB1, RPB2 (RNA polymerase II genes), Tsr1 (putative ribosome biogenesis protein) and Cct8 (putative chaperonin complex component TCP-1) gene sequences were obtained. The Trichocomaceae are divided in three separate families: Aspergillaceae, Thermoascaceae and Trichocomaceae. The Aspergillaceae are characterised by the formation flask-shaped or cylindrical phialides, asci produced inside cleistothecia or surrounded by Hülle cells and mainly ascospores with a furrow or slit, while the Trichocomaceae are defined by the formation of lanceolate phialides, asci borne within a tuft or layer of loose hyphae and ascospores lacking a slit.
