Keratinophilic fungi : Their role in nature and degradation of keratinic substrates

  title={Keratinophilic fungi : Their role in nature and degradation of keratinic substrates},
  author={Valeria Filipello Marchisio},
Keratinophilic fungi are natural colonizers of keratinic substrates. Some are keratinolytic and play an important ecological role in decomposing α-keratins, the insoluble fibrous proteins. Because of the tight packing of their polypeptide chains in α-helix structures and their linkage by disulphide bridges, they are poorly biodegradable. Two main forms of attack have been identified: surface erosion and radial penetration. In surface erosion, the sequence of degradation proceeds as the level of… CONTINUE READING
