Thethallus consists of a septate, dikaryotic mycelium, often provided with clamp connections; these are bridges between adjacent cells to provide each of them with a nucleus derived from one of the parent strains. The septa are perforated by a single, central pore. The wall of the pore canal is often characteristically swollen; such a structure is called a dolipore. Spores each produce a short-lived, haploid myce- lium. Cells of suitable mating type show plasmogamy, but karyogamy is postponed. Consequently a heterokaryon with clamp connections is formed. This condition is maintained during the major part of the life cycle, including fruitbody production. Karyogamy, immediately followed by meiosis, takes place in the basidium, which produces meiospores (basidiospores) exogenously, the spores often being forcibly discharged.

    Phylogeny of the Genus Arachnomyces and Its Anamorphs and the Establishment of Arachnomycetales, a New Eurotiomycete Order in the Ascomycota

    STUDIES IN MYCOLOGY 47: 131-139, 2002 Phylogeny of the genus Arachnomyces and its anamorphs and the establishment of Arachnomycetales, a new eurotiomycete order in the Ascomycota 1, 2 1* 3 2 C. F. C. Gibas , L. Sigler , R. C. Summerbell and R. S. Currah 1University of Alberta Microfungus Collection and Herbarium, Edmonton, Alberta, Canada; 2Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada; 3Centraalbureau voor Schimmelcultures, Utrecht, The Netherlands Abstract: Arachnomyces is a genus of cleistothecial ascomycetes that has morphological similarities to the Onygenaceae and the Gymnoascaceae but is not accommodated well in either taxon. The phylogeny of the genus and its related anamorphs was studied using nuclear SSU rDNA gene sequences. Partial sequences were determined from ex-type cultures representing A. minimus, A. nodosetosus (anamorph Onychocola canadensis), A. kanei (anamorph O. kanei) and A. gracilis (anamorph Malbranchea sp.) and aligned together with published sequences of onygenalean and other ascomycetes. Phylogenetic analysis based on maximum parsimony showed that Arachnomyces is monophyletic, that it includes the hyphomycete Malbranchea sclerotica, and it forms a distinct lineage within the Eurotiomycetes. Based on molecular and morphological data, we propose the new order Arachnomycetales and a new family Arachnomycetaceae. All known anamorphs in this lineage are arthroconidial and have been placed either in Onychocola (A. nodosetosus, A. kanei) or in Malbranchea (A. gracilis). Onychocola is considered appropriate for disposition of the arthroconidial states of Arachnomyces and thus Malbranchea sclerotica and the unnamed anamorph of A. gracilis are redisposed as Onychocola sclerotica comb. nov. and O. gracilis sp. nov.

Bacterial keratinases were also included. Temperature and substrate relationship keratinase production has also been discussed. Keratin degradation and industrial involvement of keratinase producing fungi is also reviewed. Key words : Keratinase, keratin, degradation, fungi. ______________________________________________________________________________________________ INTRODUCTION Keratin is an insoluble macromolecule requiring the secretion of extra cellular enzymes for biodegradation to occur. Keratin comprises long polypeptide chains, which are resistant to the activity of non-substrate-specific proteases. Adjacent chains are linked by disulphide bonds thought responsible for the stability and resistance to degradation of keratin (Safranek and Goos, 1982). The degradation of keratinous material is important medically and agriculturally (Shih, 1993; Matsumoto, 1996). Secretion of keratinolytic enzymes is associated with dermatophytic fungi, for which keratin

Studies in Fungi 4(1), 292–303, Doi 10.5943/sif/4/1/31 Abstract In this study, filamentous fungi were isolated from a soil sample from a farm in Mankayan, Benguet. The isolates were tested for the presence of carboxylesterase enzyme as it would indicate the ability to breakdown pyrethroid pesticides such as Cypermethrin. A total of fourteen fungal isolates were characterized morphologically and were identified using the D1/D2 regions of 28S rDNA. All were identified to be members of the Ascomycetes. Seven of the isolates belong to the genus Fusarium, and two were identified to be Aspergillus heteromorphus and Penicillium sp. All fourteen isolates exhibited carboxylesterase activity. Isolates BDP3 and BDP10 exhibited the greatest carboxylesterase activity. These two isolates, both unidentified Ascomycetes, are promising species for mycoremediation specifically targeting pyrethroid pesticides. Key words – Aspergillus heteromorphus – carboxylesterase – cypermethrin – pyrethroids Introduction The potential for bioremediation by fungi, also known as mycoremediation, is largely ignored. Singh (2006) says in his review paper that there is shortage of reports involving fungi in bioremediation because the biology and ecology of fungal metabolic processes are rarely examined.

Acta Mycol. 46 (1): 83–107, 2011. The frequency and species diversity of keratinophilic fungi in 38 nests of nine species of wetland birds were examined. nine species of geophilic dermatophytes and 13 Chrysosporium species were recorded. Ch. keratinophilum, which together with its teleomorph (Aphanoascus fulvescens) represented 53% of the keratinolytic mycobiota of the nests, was the most frequently observed species. Chrysosporium tropicum, Trichophyton terrestre and Microsporum gypseum populations were less widespread. The distribution of individual populations was not uniform and depended on physical and chemical properties of the nests (humidity, pH). Key words: Ascomycota, mitosporic fungi, Chrysosporium, occurrence, distribution INTRODUCTION Geophilic dermatophytes and species representing the Chrysosporium group (an arbitrary term) related to them are ecologically classified as keratinophilic fungi. Ke- ratinophilic fungi colonise keratin matter (feathers, hair, etc., animal remains) in the soil, on soil surface and in other natural environments. They are keratinolytic fungi physiologically specialised in decomposing native keratin. They fully solubilise na- tive keratin (chicken feathers) used as the only source of carbon and energy in liquid cultures after 70 to 126 days of growth (20°C) (Korniłłowicz-Kowalska 1997).

    SINGLE DOSE PHARMACOKINETICS OF AZITHROMYCIN IN BALL PYTHONS (Python regius) Rob L. Coke, DVM,1* Robert P. Hunter, MS, PhD,2 Ramiro Isaza, MS, DVM,1 James W. Carpenter, MS, DVM,1 David Koch, MS,2 and Marie Goatley, BS2 1Department of Clinical Sciences and the 2Department of Anatomy and Physiology, College of Veterinary Medicine, Kansas State University, Manhattan, KS 66506 USA Abstract Azithromycin is a new sub-class of macrolide antibiotics classified as an azalide. This antimicrobial has a similar mechanism of action to the other macrolides (i.e., erythromycin) by binding to the 50S ribosomal subunit.2 Azithromycin provides broad-spectrum antibiosis against gram-positive and gram-negative bacteria.2 It also has the ability to obtain sustained drug concentrations in tissues much greater than the corresponding plasma concentration.1,3 This study determined the pharmacokinetics of azithromycin (Zithromax®, Pfizer Inc., New York, NY 10017 USA) in ball pythons (Python regius), a species that is representative of the Boidae family. Snakes were administered azithromycin intravenously (i.v.) to determine distribution and orally (p.o.) to determine bioavailability and absorption. Seven ball pythons (two males, five females), weighing approximately 0.67-0.96 kg, were used in this experiment. Using a crossover design, each snake was given a single 10 mg/kg i.v. dose of azithromycin via cardiocentesis. For the oral study, each snake was dosed at 10 mg/kg using the same i.v. azithromycin preparation. Blood samples were collected prior to dosing and at 1, 3, 6, 12, 24, 48, 72, and 96 hr post-azithromycin administration.

    Journal of Basic & Applied Mycology 2 (2011): 1-27 1 © 2010 by The Society of Basic & Applied Mycology (EGYPT) An annotated check-list of Ascomycota reported from soil and other terricolous substrates in Egypt A. F. Moustafa* & A. M. Abdel – Azeem Department of Botany, Faculty of Science, University of Suez *Corresponding author: e-mail: Canal, Ismailia 41522, Egypt [email protected] Received 26/6/2010, Accepted 6/4 /2011 ____________________________________________________________________________________________________ Abstract: By screening of available sources of information, it was possible to figure out a range of 310 taxa that could be representing Egyptian Ascomycota up to the present time. In this treatment, concern was given to ascomycetous fungi of almost all terricolous substrates while phytopathogenic and aquatic forms are not included. According to the scheme proposed by Kirk et al. (2008), reported taxa in Egypt belonged to 88 genera in 31 families, and 11 orders. In view of this scheme, very few numbers of taxa remained without certain taxonomic position (incertae sedis). It is also worthy to be mentioned that among species included in the list, twenty-eight are introduced to the ascosporic mycobiota as novel taxa based on type materials collected from Egyptian habitats. The list includes also 19 species which are considered new records to the general mycobiota of Egypt. When species richness and substrate preference, as important ecological parameters, are considered, it has been noticed that Egyptian Ascomycota shows some interesting features noteworthy to be mentioned. At the substrate level, clay soils, came first by hosting a range of 108 taxa followed by desert soils (60 taxa).

    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).
