Abstract:
Over 24 million tons of chicken feather waste are generated annually by global poultry production, and improper disposal contributes to environmental hazards and loss of protein-rich resources. Keratinases, produced by microbes such as Bacillus and Aspergillus, play a crucial role in degrading resistant keratin from feathers, enabling their conversion into value-added products like organic fertilizers, animal feed, and biotechnological materials. The high keratin content of poultry feather waste makes it a significant environmental disposal challenge due to its slow degradation. The aim of the study was to produce and optimize keratinase from an indigenously isolated fungal source, characterize its activity and stability, and apply it to hydrolyze chicken feathers for the development off eather protein hydro lysate. Keratin was extracted from the chicken feathers to obtain a high yield of keratin. The yield of keratin was optimized by varying NaOH concentration, HCL concentration, alkaline hydrolysis time and neutralization time and its properties were analyzed through various biochemical and spectroscopic techniques such as SEM, FTIR and XRD, with the results indicating that higher amount of keratin production from chicken feathers and it was potential for future industrial applications. Keratinase was produced from microorganisms and then their production was optimized via BBD model of RSM. The study is consistent with the goals of environmental sustainability, economic development, and the advancement of green biotechnology and as a result feather protein hydro lysate can be utilized as a slow-release organic fertilizer, particularly for nitrogen, to provide an organic supply of nitrogen fertilizer.
