Nutritional Enhancement of Chicken Feather Waste by Bacillus aerius NSMk2.

ABSTRACT: Keratinous waste is the bulk by-product of various livestock industries. Slow natural degradation of keratin and less efficient chemical hydrolysis imposes challenge for the search of alternative recycling methods. Keratin degrading microbes hydrolyse keratin to soluble peptides and amino acids. Bacillus aerius NSMk2 showed great potential for hydrolysis of chicken feather waste. Bacillus aerius NSMk2 cells grown in phosphate buffer supplemented with chicken feathers showed high disulfide reductase activity and release of sulfhydryl groups. The release of proteins and amino acids were statistically optimized at varied pH (4.0-11.0), temperature (30.0-45.0 °C) and agitation (100-250 rpm), and maximum release was recorded at pH 7.5, temperature 37 °C and shaking (175 rpm).
