Advanced reduction and adsorption for trace organic contaminant removal from water

The rising world population and overall increase in living standards creates a global pressure on the supply of clean fresh water. This is tied to an increasing use of chemicals (e.g. pesticides, pharmaceuticals, …), which may end up in the environment and our water sources as trace organic contaminants (TrOCs). In order to protect both the ecosystem and our drinking water, these TrOCs need to be removed. Established technologies applied in water treatment for TrOC removal include oxidation, activated carbon adsorption, and their combination. However, these technologies are accompanied with their drawbacks. In this PhD thesis, new technologies are introduced and investigated, in order to find out whether or not they can result in a more efficient TrOC removal. Catalytic reduction was coupled to activated carbon adsorption, where it was shown that a reductive TrOC transformation can result in enhanced subsequent removal on AC, however this was not universally the case for all TrOCs. Advanced reduction, in which highly reducing radicals are generated, resulted in an efficient removal of almost all TrOCs. Through identification of transformation products, it was observed that TrOC dehalogenation was mostly favored by hydrated electron radicals. In different water matrices, however, the efficiency of TrOC removal with advanced reduction decreased considerably. Finally, molecularly imprinted polymeric adsorbents were tested for selective TrOC removal. Target TrOCs can indeed selectively be removed, depending on the applied adsorbent and targeted TrOC class

Identity and typification of Achroomyces effusus (Pucciniomycotina, Basidiomycota)

The identity of Achroomyces effusus is re-established with the use of morphological and DNA methods, and a neotype is selected. The species is conspecific with Colacogloea peniophorae, the generic type of Colacogloea, and has a priority over it. A new combination, C. effusa, is proposed.Peer reviewe

On Sistotremastrum and similar-looking taxa (Trechisporales, Basidiomycota)

The taxonomy of Sistotremastrum (Trechisporales, Basidiomycota) is revised based on morphology and DNA data. The genus is shown to be polyphyletic, and therefore it is split into two units-Sistotremastrum s. str. and Sertulicium, gen. nov. (typified with Corticium niveocremeum). Sistotremastrum s. str. is retained for eleven species of which eight are described as new while Sertulicium encompasses at least six species, including one new to science. Both of these genera are only distantly related to other representatives of the Trechisporales. Additionally, a new poroid neotropical species, Porpomyces abiens (Hydnodontaceae), is described as morphologically similar to some members of Sistotremastrum s. str.peerReviewe

Fungal systematics and evolution : FUSE 6

Fungal Systematics and Evolution (FUSE) is one of the journal series to address the “fusion” between morphological data and molecular phylogenetic data and to describe new fungal taxa and interesting observations. This paper is the 6th contribution in the FUSE series—presenting one new genus, twelve new species, twelve new country records, and three new combinations. The new genus is: Pseudozeugandromyces (Laboulbeniomycetes, Laboulbeniales). The new species are: Albatrellopsis flettioides from Pakistan, Aureoboletus garciae from Mexico, Entomophila canadense from Canada, E. frigidum from Sweden, E. porphyroleucum from Vietnam, Erythrophylloporus flammans from Vietnam, Marasmiellus boreoorientalis from Kamchatka Peninsula in the Russian Far East, Marasmiellus longistipes from Pakistan, Pseudozeugandromyces tachypori on Tachyporus pusillus (Coleoptera, Staphylinidae) from Belgium, Robillarda sohagensis from Egypt, Trechispora hondurensis from Honduras, and Tricholoma kenanii from Turkey. The new records are: Arthrorhynchus eucampsipodae on Eucampsipoda africanum (Diptera, Nycteribiidae) from Rwanda and South Africa, and on Nycteribia vexata (Diptera, Nycteribiidae) from Bulgaria; A. nycteribiae on Eucampsipoda africanum from South Africa, on Penicillidia conspicua (Diptera, Nycteribiidae) from Bulgaria (the first undoubtful country record), and on Penicillidia pachymela from Tanzania; Calvatia lilacina from Pakistan; Entoloma shangdongense from Pakistan; Erysiphe quercicola on Ziziphus jujuba (Rosales, Rhamnaceae) and E. urticae on Urtica dioica (Rosales, Urticaceae) from Pakistan; Fanniomyces ceratophorus on Fannia canicularis (Diptera, Faniidae) from the Netherlands; Marasmiellus biformis and M. subnuda from Pakistan; Morchella anatolica from Turkey; Ophiocordyceps ditmarii on Vespula vulgaris (Hymenoptera, Vespidae) from Austria; and Parvacoccum pini on Pinus cembra (Pinales, Pinaceae) from Austria. The new combinations are: Appendiculina gregaria, A. scaptomyzae, and Marasmiellus rodhallii. Analysis of an LSU dataset of Arthrorhynchus including isolates of A. eucampsipodae from Eucampsipoda africanum and Nycteribia spp. hosts, revealed that this taxon is a complex of multiple species segregated by host genus. Analysis of an SSU–LSU dataset of Laboulbeniomycetes sequences revealed support for the recognition of four monophyletic genera within Stigmatomyces sensu lato: Appendiculina, Fanniomyces, Gloeandromyces, and Stigmatomyces sensu stricto. Finally, phylogenetic analyses of Rhytismataceae based on ITS–LSU ribosomal DNA resulted in a close relationship of Parvacoccum pini with Coccomyces strobi.http://www.sydowia.at/index.htmpm2021Medical Virolog
