Feathers are the most prevalent agricultural waste generated by chicken farms, polluting environment and wasting protein resources as a result of accumulation large amounts feathers. Therefore, keratinase-producing microorganisms represent promising potential technique for degradation feather waste. Streptomyces netropsis A-ICA Bacillus subtilis ALICA, previously isolated from rhizosphere deser...

MEP3 of Microsporum canis encodes a 43.5 kDa extracellular keratinolytic metalloprotease, which is thought to be one of the virulence-related factors in dermatophytosis. In order to analyze the system underlying the regulation of MEP3 gene expression, the 5'-upstream region was isolated by inverse PCR. The nucleotide sequence of a DNA fragment of about 2.1 kb containing the coding region contai...

The present study deals with isolation, identification and characterization of feather degrading bacterium. The keratinolytic bacteria were isolated from feather dumped soil. The colonies showed higher keratinase production was identified as Bacillius sp, as per Bergey’s manual method. Keratinase producing Bacillus sp, showed higher enzymes production. The crude filtrate showed specific activit...

A novel thermophilic, anaerobic, keratinolytic bacterium designated KD-1 was isolated from grassy marshland. Strain KD-1 was a spore-forming rod with a Gram-positive type cell wall, but stained Gram-negative. The temperature, pH, and NaCl concentration range necessary for growth was 30-65 °C (optimum 55 °C), 6.0-10.5 (optimum 8.0-8.5), and 0-6% (optimum 0.2%) (w/v), respectively. Strain KD-1 po...

The keratinase (kerA) gene from Bacillus licheniformis PWD-1 was expressed and purified in insect cells. First, the sequence encoding Ker-His-Flag was designed based on the amino acid sequence of the protein and peptide and codon optimization in order to ensure the high expression in insect cells. In the next step, the synthetic DNA was inserted into the pUC57 vector and then sub-cloned in the ...

Background: The etiologic role of Malassezia furfur in onychomycosis, because of its controversial keratinolytic ability, has not been proven. The most reported cases are distal subungual onychomycosis (DSO). In our knowledge no cases of proximal onychomycosis (PO) has been reported. For the first time we report proximal onychomycosis. This case report describes the isolation of Malassezia furf...
