“…Microbial conversion of keratinous wastes constitutes a potential technique for their biodegradation and valorisation with respect to cost-effectiveness and environment protection (Shih, 1993;Dalev, 1994). In this work, a feather-degrading bacterium, B. pumilus A1 was used to produce FPH, which was examined for its capacity to contain metabolisable protein and antioxidant peptides.…”

“…Enzymatic-alkaline hydrolysis of feather keratin for feed was done by (Dalev 1994;Dalev et al 1996). Enzymatic modification through enrichment with lysine leads to increase in the feed nutritive value (Dalev et al 1997) Raw horns and hoofs are put on high pressure in a rendering plant to make horn meal.…”

“…Proteases can solubilize proteins in waste streams, resulting in recoverable liquid concentrates or dry solids of nutritional value for fish or livestock (Shoemaker, 1986). Dalev (1994) reported the use of alkaline protease from Bacillus subtilis in the processing of waste feathers from poultry slaughterhouses. Feathers constitute 5% of the body weight of poultry and can be considered as a high protein source for food and feed provided their rigid keratin structure is completely destroyed.…”
