Two novel species of Aspergillus section Nigri from Thai coffee beans are described as Aspergillus aculeatinus sp. nov. and Aspergillus sclerotiicarbonarius sp. nov. Their taxonomic status was determined using a polyphasic taxonomic approach with phenotypic (morphology and extrolite profiles) and molecular (beta-tubulin, internal transcribed spacer and calmodulin gene sequences) characteristics...
هدف: آلودگی نفتی از مشکلات مهم محیط زیست است. اخیرا زیست پالائی به عنوان روشی کم هزینه جهت پاکسازی آلایندهها مورد توجه قرار گرفته است. هدف از این مطالعه بررسی حذف زیستی نفت خام توسط گونههای مختلف قارچی جداسازی شده از ریزوسفر گیاهان رویش یافته در منطقه آلوده مورد بررسی در غلظتهای مختلف آلاینده میباشد. مواد و روشها: در این مطالعه قارچ های ریزوسفری از گیاهان رویش یافته در منطقه پالایشگاه تهر...
RES-1149-1 and -2, produced by Aspergillus sp. RE-1149, were found to be non-peptidic antagonists for endothelin type B receptor (ET(B) receptor). RES-1149-1 and -2 selectively inhibited the endothelin-1 (ET-1) binding to ET(B) receptor in a competitive manner with IC50 values of 1.5 microM and 20 microM, respectively. RES-1149-1 inhibited the increase in intracellular Ca2+ concentration elicit...
Polygalacturonases production by newly isolated Monascus sp N8 and Aspergillus sp N12 strains was carried out in solid-state fermentation using mixtures of wheat bran, sugar cane bagasse and orange bagasse as carbon sources. The maximal activity values of exo-polygalacturonases (exo-Pg) from Monascus sp and Aspergillus sp were obtained using wheat bran/sugar cane bagasse/orange bagasse mixture ...
Aspergillus section Nigri includes some of the most important species for biotechnology and its species are of widespread occurrence. During our surveys of various food products and tropical soil we isolated several aspergilli belonging to section Nigri. In this paper, four new sclerotium and/or ochratoxin A producing species belonging to this section are proposed. In addition, based on a polyp...
We a case of chronic Aspergillus sp. meningitis in a healthy 43-year-old woman successfully treated with fluconazole given orally (300 ms/day). The diagnosis was made by detection of anti-aspergillus antibodies and positive culture to Aspergillus sp. in the cerebrospinal fluid.
In this study, we examined the microbial population in different parts, gill, muscles and intestine region of Channa punctatus from two different fish culture farm. Based on their growth characteristics on specific culture media, the following human bacterial pathogen such as Achromobacter xylosoxidans (Gram +ve), Acinetobacter anitratus (Gram -ve), Bacillus subtilis (Gram +ve), Proteus vulgari...
Aspergillus sp. P37 is an arsenate-hypertolerant fungus isolated from a river in Spain with a long history of contamination with metals. This strain is able to grow in the presence of 0.2 M arsenate, i.e. 20-fold higher than the reference strain, Aspergillus nidulans TS1. Although Aspergillus sp. P37 reduces As(V) to As(III), which is slowly pumped out of the cell, the measured efflux of oxyani...
The aim of the present investigation was to assess and compare the antimicrobial activities of the lemon (Citrus sinensis) peel extract and lemon oil against common food borne pathogens and to study their potential as food bio-preservatives. The antagonistic activity of lemon peel extract and lemon oil was studied against common food borne pathogens like Staphylococcus aureus, Staphylococcus ep...
Feline upper respiratory tract aspergillosis (URTA) is an emerging infectious disease. The aims of this study were: (1) to assess the diagnostic value of detection of Aspergillus-specific antibodies using an agar gel double immunodiffusion (AGID) assay and an indirect immunoglobulin G (IgG) ELISA; and (2) to determine if an aspergillin derived from mycelia of Aspergillus fumigatus, Aspergillus ...
