A new species of Mahabalella B. Sutton & S. D. Patil was isolated from decaying leaves an unidentified plant, during a survey in the Charles Darwin Ecological Refuge Igarassu, Pernambuco, Brazil, June 2018. The is morphologically distinguishable other by size their conidia, conidiogenous cells and setae. In this study, morphological descriptions, illustrations cultural characteristics for perna...
Discovered in Paraguay, Chlorophyllum sapukai is a new species based on morphological characters and multigene molecular phylogenetic analyses (ITS, LSU, RPB2 TEF1 markers). Macroscopically, the characterized by large agaricoid basidiomata, with hemispherical to broad convex pileus, yellowish cream buff surface of pileus covered centrally plate-like squamules. Microscopically, abundant cheilocy...
Abstract The genus Ceratocystiopsis ( Ophiostomatales , Ascomycota ) includes 21 species, which can be found mainly in association with bark beetles the Northern Hemisphere. A survey of species associated infesting Picea abies and Pinus sylvestris Norway yielded 126 isolates, representing neglecta rollhanseniana four described herein as chalcographii debeeria norroenii troendelagii . new taxa w...
A well resolved phylogeny of the Agaricaceae based on partial rpb2 sequences is presented from a wide geographic and systematic sampling of the family and compared to phylogenies based on nrLSU and tef1 sequences. A smaller dataset of the family focusing on the Agaricus clade of nrITS sequences and a combined dataset were used to determine the position of several white-spored taxa from northern...
Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecu...
Morphological studies and phylogenetic analyses of DNA sequences from the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of the large exon of tef1 (LEtef1) were used to investigate the taxonomy and systematics of nine Hypocrea species with anamorphs assignable to Trichoderma sect. Hyp...
Three new species of Phyllosticta, P. hostae on Hosta plantaginea (China), P. schimae on Schima superba (China), and P. ilicis-aquifolii on Ilex aquifolium (UK), are described and illustrated in this study. They are compared with morphologically similar and phylogenetically closely related species. A polyphasic approach using phylogeny, host association, disease symptoms, colony and morphologic...
We present a comprehensive phylogeny derived from 5 genes, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, for 356 isolates and 41 families (six newly described in this volume) in Dothideomycetes. All currently accepted orders in the class are represented for the first time in addition to numerous previously unplaced lineages. Subclass Pleosporomycetidae is expanded to include the aquatic order Jahnu...
Baudoinia was described to accommodate a single species, B. compniacensis. Known as the 'whiskey fungus', this species is the predominant member of a ubiquitous microbial community known colloquially as 'warehouse staining' that develops on outdoor surfaces subject to periodic exposure to ethanolic vapours near distilleries and bakeries. Here we examine 19 strains recovered from environmental s...
آنزیم های α-آمیلاز کاربرد وسیعی در صنایع غذایی، داروسازی، نساجی و شوینده دارند. α-آمیلازهای تولیدشده توسط منابع میکروبی مختلف دارای خواص آنزیمی متفاوتی می باشند. آنزیم α-آمیلاز تولید شده توسط سویه bacillus sp.kr-8104 وابسته به یون کلسیم نمی باشد و همچنین بیشترین فعالیت آن درمحدوده ) ph6-4( گزارش شده است. با توجه به خواص ذکر شده، این آنزیم مورد توجه بسیاری از صنایع به ویژه صنعت نشاسته قرار دارد....
