Keratinolytic Properties of Aspergillus clavatus Promising for Biodegradation

Abstract: The high demand for keratinolytic enzymes and the modest presentation of fungal keratinase diversity studies in scientific sources cause a significant interest in identifying new fungal strains of keratinase producers, isolating new enzymes and studying their properties. Four out of the 32 cultures showed a promising target activity on protein-containing agar plates—Aspergillus amstelodami A6, A. clavatus VKPM F-1593, A. ochraceus 247, and Cladosporium sphaerospermum 1779. The highest values of keratinolytic a… Show more

“…Максимальные значения кератинолитической активности (96,1 Е) были получены на среде с куриным пером и ГРМ на 6-е сут культивирования (рис. 1, 2), что подтверждает данные о перспективности использования этой среды для получения кератиназ [18].…”
