The etiologic role of Malassezia furfur in onychomycosis is a contentious diagnostic problem because its keratinolytic ability has never been verified. This case report describes the isolation of M. furfur from the infected nails of a child clinically diagnosed with onychomycosis, and discusses the role of this organism as an etiologic agent/colonizer. The patient presented with subungual hyper...

The aim of our study was to determine the prevalence of keratinophilic and keratinolytic fungi in the soil of recreational areas in Lodz, with a particular emphasis on species potentially pathogenic for humans. The material consisted of 104 soil samples collected from the surface layer and 10-15 cm below the surface at 26 recreational areas in Lodz. Soil samples were inoculated on Sabouraud, Cz...

The keratinolytic activities of dermatophytes which parasitize skin, nails, and hair have been described previously (1, 3, 6, 8); however, the isolation of a keratinase from these organisms has not yet been reported. Trichophyton mentagrophytes var. granulosum (T. granulosum Sabouraud, 1909) was grown in a keratin medium composed of (per liter): horse hair, 2.5 g; glucose, 0.9 g; MgSO4.7H20, 0....

The use of fertilizers based on organic waste as a result microbial biodegradation and biotransformation is becoming increasingly common practice in plant cultivation. This to limit the chemicals used agriculture thus protect environment consumer health. aim this study was evaluate hitherto unexplored effect hydrolysates obtained after chicken feather by soil strain keratinolytic fungus Trichop...

This paper assesses the ability of strains of Aphanoascus fulvescens and Chrysosporium articulatum isolated from soil (phaesol) to degrade native feather keratin. Strains were identified based on phenotypic traits and nucleotide sequencing. Response Surface Methodology was used to optimize cultivation conditions exhibiting the highest keratinolytic activity. The experiments were based on Box-Be...

Paecilomyces lilacinus (Thom) Samson LPS 876, a locally isolated fungal strain, was grown on minimal mineral medium containing "hair waste," a residue from the hair-saving unhairing process, and produced a protease with keratinolytic activity. This enzyme was biochemically characterized. The optimum reaction conditions, determined with a response surface methodology, were 60°C and pH 6.0. It wa...

Keratins are tough, fibrous proteins found as the major protein component in hair. Chemical hair removal is harsh and results severe toxicity pollution, hence, a need for non-chemical enzymatic process. The aim of this study to characterise keratinase from isolated keratin-degrading Bacillus licheniformis-K51, subtilis-K50 sp.-K53 investigate its potential removal. collagenolytic ability kerati...
