INTRODUCTION There are suspended fungal spores in the air and in the nasal mucosa of adults, especially in areas with a humid climate. Several studies have revealed the role of fungi in the pathogenesis of chronic rhinosinusitis (CRS) in recent years but it is a topic of controversy, especially in regions with low humidity. The aim of this study was to evaluate the prevalence of fungal species ...

Transgenic filamentous fungi of the species Aspergillus niger, A. nidulans and A. awamori expressing and secreting Erwinia carotovora (Eca) subsp. atroseptica pectate lyase 3 (PL3) were generated. Correct processing of the pre-enzyme was achieved using the A. niger pectin lyase A (PEL A) signal peptide. With the prepro-peptide of A. niger polygalacturonase II, secreted enzymes still possessed t...

The isolated fungi species of different kinds from chromium contaminated soil sites located in Nagalkeni, Chennai were used for reducing chromium(VI) in a tannery industry wastewater of Nagalkeni, Chennai.  The experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(VI) in a tannery industry wastewater against the different pH, fungi biomass and ...

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...

The suitability of protein and glucosamine measurements of cell components for biomass estimation of fungi Aspergillus niger S,4, a mangrove isolate, and Aspergillus oryzae NCIM 1212 was evaluated using wheat bran as substrate in solid-state fermentation (SSF). Both direct as well as indirect methods were used. The protein and glucosamine contents and direct weight of the fungi were determined ...

Aflatoxigenic Aspergillus fungi and associated aflatoxins are ubiquitous in the production and storage of food/feed commodities. Controlling these microbes is a challenge. In this study, the Shewanella algae strain YM8 was found to produce volatiles that have strong antifungal activity against Aspergillus pathogens. Gas chromatography-mass spectrometry profiling revealed 15 volatile organic com...

Wastewater from swine confined-housing operations contains elevated levels of copper and zinc due to their abundance in feed. These metals may accumulate to phytotoxic levels in some agricultural soils of North Carolina due to land application of treated swine effluent. We evaluated fungi for their ability to remove these metals from wastewater and found Aspergillus niger best suited for this p...

The essential oil extracted from the epicarp of Citrus sinensis exhibited absolute fungitoxicity against soybean’s fungus as Alternaria alternate, Aspergillus niger, Cercospora kikuchii, Chaetomium spp., Cladosporium cladosporioides, Curvularia lunata, Fusarium roseum, Macrophomina phaseolina, Penicillium italicum, Phomopsisspp. Rhizoctonia solani, and Sclerotium rolfsii. It is very difficult t...

introduction otomycosis is a common infection of the external ear that is seen in the tropical and subtropical areas of the world. we performed mycologic analysis by obtaining samples from the external auditory canal in patients clinically diagnosed with otomycosis. methods 174 patients with clinical suspicion of otomycosis referred to the otolaryngology clinic of al-zahra and kashani hospitals...

Filamentous fungi possess unique features which make them attractive as hosts for the production of heterologous gene products. For example, certain fungal species are capable of secreting large quantities of protein in submerged culture. Selected strains of Aspergillus niger can produce greater than 20 g of glucoamylase I ~ I in industrial fermentations [ 11. Some filamentous fungi, including ...
