the aim of the present study was to isolate and identify parasites and saprophytes from fungal affected eggs of rainboe trout.the samples (n= 900) were obtained from six fish farm and transferred to mycology laboratory in stril tubes . the samples were inoculated in cculture media , (sda, cma, gpagar and hemp seeds cultures) at room temperature (18-24°c) . twelve species of fungi isolated from ...

An extracellular thermostable xylanase (Xyl-IIb) produced by Penicillium citrinum isolate HZN13 was purified to homogeneity using DEAE-Sepharose, Sephadex G-100 and Bio-Gel P-60 chromatography with specific activity of 6272.7 U/mg and 19.6-fold purification. The purification revealed the occurrence of multiple forms of xylanases (Xyl-I, Xyl-IIa, Xyl-IIb and Xyl-III). The molecular mass of highl...

Filamentous fungi produce a multitude of secondary metabolites, some of them known as mycotoxins, which are toxic to vertebrates and other animal groups in low concentrations. Among them, penitrems, which belong to the group of indole-diterpene mycotoxins, are synthesized by Penicillium and Aspergillus genera and exhibit potent tremorgenic effects. This is the first complex study of the penitre...

An endoxylanase gene (PoxynA) that belongs to the glycoside hydrolase (GH) family 11 was cloned from a xylanolytic strain, Penicillium oxalicum B3-11(2). PoxynA was overexpressed in Trichoderma reesei QM9414 by using a constitutive strong promoter of the encoding pyruvate decarboxylase (pdc). The high extracellular xylanase activities in the fermentation liquid of the transformants were maintai...

Penicillium notatum is a well-known indoor aeroallergen and is frequently included in skin test panels for allergic diagnosis. On two-dimensional immunoblotting using patients' sera containing IgE and monoclonal antibody D7B8 specific for Pen c 1 of P. citrinum, two allergens with a molecular mass of 33 kDa but different isoelectric points were identified. A novel cDNA coding for Pen n 13 was c...

A novel cold-adaptive xylanolytic Penicillium strain FS010 was isolated from Yellow sea sediments. The marine fungus grew well from 4 to 20 degrees; a lower (0 degrees) or higher (37 degrees) temperature limits its growth. The strain was identified as Penicillium chrysogenum. Compared with mesophilic P. chrysogenum, the cold-adaptive fungus secreted the cold-active xylanase (XYL) showing high h...

Verbesina encelioides belongs to the Asteraceae family and also known as golden crown beard wild sunflower. In present study callus was raised from leaf explant of V. encelioides. Callus obtained on MS medium. The used for antifungal activity identification. in-vitro anti-fungal Candida albicans gave most effective response out all studied fungi, with best being displayed in methanol extract fo...

13 samples were collected from phone screens and headphones, the sample was by a cotton swab planted on Petri dishes. A number of fungal species isolated, their reached six types fungi, where most common fungi in Aspergillus, while headphones are Penicillium Aspergillus fungi. In addition to that, highest frequency with an incidence rate 30.76%, headphone Penicillium, 30.76%.

Pectin lyase and polygalacturonase production by newly isolated fungal strains was carried out in solid-state fermentation. Moniliella SB9 and Penicillium sp EGC5 produced polygalcturonase (PG) and pectin lyase (PL) on mixture of orange bagasse, sugar cane bagasse and wheat bran as substrate. PG and PL produced by Moniliella presented optimum activity at pH 4.5 and 10.0 and at 55 and 45°C, resp...
