Studies in Fungi 5(1), 6–16, Doi 10.5943/sif/5/1/2 Abstract Microfungi are commonly inhabited soil with various roles. The present study was conducted in order to isolate and identify microfungi from soil samples in Serdang, Selangor, Malaysia. In this study, the soil microfungi were isolated using serial dilution technique and spread plate method. A total of 25 isolates were identified into ten genera based on internal transcribed spacer region (ITS) sequence analysis, namely Aspergillus, Clonostachys, Colletotrichum, Curvularia, Gliocladiopsis, Metarhizium, Myrmecridium, Penicillium, Scedosporium and Trichoderma consisting 18 fungi species. Aspergillus and Penicillium species were claimed as predominant microfungi inhabiting the soil. Findings from this study can be used as a checklist for future studies related to fungi distribution in tropical lands. For improving further study, factors including the physicochemical properties of soil and anthropogenic activities in the sampling area should be included.

  • Citric Acid and Itaconic Acid Accumulation: Variations of the Same Story?
    Applied Microbiology and Biotechnology https://doi.org/10.1007/s00253-018-09607-9 MINI-REVIEW Citric acid and itaconic acid accumulation: variations of the same story? Levente Karaffa 1 & Christian P. Kubicek2,3 Received: 5 December 2018 /Revised: 28 December 2018 /Accepted: 28 December 2018 # The Author(s) 2019 Abstract Citric acid production by Aspergillus niger and itaconic acid production by Aspergillus terreus are two major examples of technical scale fungal fermentations based on metabolic overflow of primary metabolism. Both organic acids are formed by the same metabolic pathway, but whereas citric acid is the end product in A. niger, A. terreus performs two additional enzymatic steps leading to itaconic acid. Despite of this high similarity, the optimization of the production process and the mechanism and regulation of overflow of these two acids has mostly been investigated independently, thereby ignoring respective knowledge from the other. In this review, we will highlight where the similarities and the real differences of these two processes occur, which involves various aspects of medium composition, metabolic regulation and compartmentation, transcriptional regulation, and gene evolution. These comparative data may facilitate further investigations of citric acid and itaconic acid accumulation and may contribute to improvements in their industrial production.

  • Lists of Names in Aspergillus and Teleomorphs As Proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (Doi: 10.3852/14-0
    Lists of names in Aspergillus and teleomorphs as proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (doi: 10.3852/14-060), based on retypification of Aspergillus with A. niger as type species John I. Pitt and John W. Taylor, CSIRO Food and Nutrition, North Ryde, NSW 2113, Australia and Dept of Plant and Microbial Biology, University of California, Berkeley, CA 94720-3102, USA Preamble The lists below set out the nomenclature of Aspergillus and its teleomorphs as they would become on acceptance of a proposal published by Pitt and Taylor (2014) to change the type species of Aspergillus from A. glaucus to A. niger. The central points of the proposal by Pitt and Taylor (2014) are that retypification of Aspergillus on A. niger will make the classification of fungi with Aspergillus anamorphs: i) reflect the great phenotypic diversity in sexual morphology, physiology and ecology of the clades whose species have Aspergillus anamorphs; ii) respect the phylogenetic relationship of these clades to each other and to Penicillium; and iii) preserve the name Aspergillus for the clade that contains the greatest number of economically important species. Specifically, of the 11 teleomorph genera associated with Aspergillus anamorphs, the proposal of Pitt and Taylor (2014) maintains the three major teleomorph genera – Eurotium, Neosartorya and Emericella – together with Chaetosartorya, Hemicarpenteles, Sclerocleista and Warcupiella. Aspergillus is maintained for the important species used industrially and for manufacture of fermented foods, together with all species producing major mycotoxins. The teleomorph genera Fennellia, Petromyces, Neocarpenteles and Neopetromyces are synonymised with Aspergillus. The lists below are based on the List of “Names in Current Use” developed by Pitt and Samson (1993) and those listed in MycoBank (www.MycoBank.org), plus extensive scrutiny of papers publishing new species of Aspergillus and associated teleomorph genera as collected in Index of Fungi (1992-2104).
