Molecular characterization of keratin degrading fungi isolated from semi-arid soil by PCR using ITS4 and ITS5 primers

Characterization of Bacteria Degrading Petroleum Derivatives Isolated from Contaminated Soil and Water

Keratin Production by Decomposing Feather Waste Using Some Local Bacillus spp. Isolated from Poultry Soil

Background; Feather waste is generated in large amounts as a by-product of commercial poultry processing. The main component of feather is keratin. The main purpose of this study was to identify Bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. Methods; Bacillus spp. Were isolated from the waste of poultries located in Miyaneh city. The bact...

Molecular characterization of hetR gene from Cylindrospermum stagnale A1345 isolated from arid soil

HetR gene is a key regulator of heterocyst differentiation in filamentous cyanobacteria. It has been previously isolated and characterized from heterocystous cyanobacterium like Anabaena that has intercalary heterocysts and from non-heterocystous cyanobacteria like Trichodesmium and Symploca PCC 8002. This study reports the characterization of hetR gene from Cylindrospermum stagnale A1345, a cy...

Molecular characterization of Mycoplasma synoviae isolated from broiler chickens of West Azarbaijan province by PCR of vlhA gene

Mycoplasma synoviae (MS) is a pathogen responsible for respiratory and locomotor disorders and causes major economic losses in poultry industry. Early and accurate diagnosis of MS infection plays a major role in control of the infection. This study was conducted to characterize Iranian field isolates of MS isolated from broiler chickens of West Azarbaijan province (Northwest of Iran), ...

Determination of keratin degradation by fungi using keratin azure.

Azure dye-impregnated sheep's wool keratin (keratin azure) was incorporated in a high pH medium and overlaid on a keratin-free basal medium. The release and diffusion of the azure dye into the lower layer indicated production of keratinase. Fifty-eight fungal taxa, including 49 members of the Arthrodermataceae, Gymnoascaceae and Onygenaceae (Order Onygenales), were assessed for keratin degradat...
