For a long time, the main interest in marine environment, considered extreme, was isolation and identification of natural products with biological properties, for that, numerous organisms chemical structures have been studied. Thus, bacteria isolated from various substrates, such as sediments, seawater, mangrove detritus, are producers enzymes different activities, i.e., amylase, cellulase, alg...

Dermatophytes can digest keratin and other proteinaceous substrates present in skin and its appendages such as nail, hair, and feather and use it as its sole source of carbon and nitrogen. Proteolytic and keratinolytic activities of dermatophytes have been a subject of interest for several years to understand the pathogenicity of infection. In this study we intend to elucidate the keratinase ac...
