Feathers, a significant by-product of the poultry industry, pose considerable waste management challenges due to their abundance and resistance degradation. This study explores potential utilizing chicken feather as sustainable protein source through microbial fermentation. We employed Aspergillus terreus UniMAP AA-1, keratinolytic fungus for fermentation aimed at degrading keratin. Various conditions, including initial pH, time, inoculum size were tested using fractional factorial design optimize yield. The highest hydrolysate concentration achieved was 5.92 mg/mL, obtained with an 5%, duration 10 days, pH 10.0. These results underscore effectiveness AA-1 in transforming into valuable hydrolysate. research contributes advancement eco-friendly economically viable methods valorizing by-products, addressing environmental issues while providing innovative sources livestock feed formulations.

Hydrolyzed keratin (HK) refers to any hydrolysate of a different origin derived by acid, alkali, enzymatic, or other methods hydrolysis. HK is water soluble and has distinct chemical–physical properties compared fibrous keratin. Although employed across various technological sectors, there notable gap in the literature regarding detailed commercially available HKs. This study aims address this providing thorough analysis surface-active, emulsifying, thickening three The results reveal relevant differences among HKs marketed under International Nomenclature Cosmetic Ingredient (INCI) name "Hydrolyzed Keratin," with variations their properties, primarily influenced molecular weight. Specifically, higher average Mw (>3000 Da) protein content demonstrate enhanced emulsifying capabilities. Conversely, low (<1000 do not show surface-active suitable for preparation emulsions. Therefore, underscores need standardization products obtain biomaterials tailored specific enhancing potential applications cosmetic pharmaceutical topical formulations.
