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...

“…It can be assumed that P. oxalicum can also metabolize other acidic substances. This functional fungus can produce secondary metabolites (such as secalonic acid A), and the unknown components in Figure 2 may be secondary metabolites (Wang et al, 2013). They were not components of interest, and further studies are required to identify these compounds that are beyond the scope of this study.…”

Large-scale discharge of bauxite residue, an alkaline, saline and nutrientdeficient waste material produced in the process of alumina production, has created extreme environments that are challenging to restore. Microbial pathways are found to play a critical role in the rehabilitation of these residues. In this study, Penicillium oxalicum, an alkaliresistant acid-producing fungus screened from bauxite residue disposal sites, was used to examine its effectiveness for restoration of bauxite residue. By comparing different biomass pretreatment methods, steam explosion pretreatment biomass was added to the medium to enhance microbial metabolism, through production of organic acids and various enzymes. P. oxalicum mainly secreted oxalic acid, formic acid and acetic acid. Addition of pretreatment biomass and microbes significantly lowered bauxite residue pH, whilst increasing EC and enzyme activity. Furthermore, the metabolic process of this fungus may promote the release of basic ions dominated by Na + and increase soluble cations. This study provides an experimental demonstration of bioremediation in bauxite residue, and enables future large-scale simulation of vegetation establishment on bauxite residue disposal areas.
