Journal ArticleDOI
Biochemical features of microbial keratinases and their production and applications.
TL;DR: Keratinases are exciting proteolytic enzymes that display the capability to degrade the insoluble protein keratin and their use in biomass conversion into biofuels may address the increasing concern on energy conservation and recycling.
Journal ArticleDOI
Characterization of a new keratinolytic bacterium that completely degrades native feather keratin.
TL;DR: A novel feather-degrading microorganism was isolated from poultry waste, producing a high keratinolytic activity when cultured on broth containing native feather, and complete feather degradation was achieved during cultivation.
Journal ArticleDOI
Characterization of a protease of a feather‐degrading Microbacterium species
TL;DR: Aims: To characterize a new feather‐degrading bacterium.
Journal ArticleDOI
Purification and characterization of a keratinolytic metalloprotease from Chryseobacterium sp. kr6
Alessandro Riffel,Adriano Brandelli,Cláudia de M. Bellato,Gustavo H.M.F. Souza,Marcos N. Eberlin,Flavio Cesar Almeida Tavares +5 more
TL;DR: ESI-MS/MS analysis of peptides generated from a tryptic digestion revealed sequence homology which may characterize the Q1 keratinase as a member of the M14 metalloprotease family, with a consensus glycosylation region similar to proteins from Chryseobacerium meningosepticum.
Journal ArticleDOI
In vitro antimicrobial activity of a new series of 1,4-naphthoquinones.
Alessandro Riffel,Luis Fernando da Costa Medina,Valter Stefani,Rosane Catarina dos Santos,Delmar Bizani,Adriano Brandelli +5 more
TL;DR: Results indicate an effective in vitro activity of 5-amino-8-hydroxy-1,4-naphthoquinone and encourage further studies for its application in antibiotic therapy.
