Fungal decomposition of chicken-feather waste in submerged and solid-state fermentation

Abstract Poultry industry is expanding rapidly and producing million tons of feather waste annually. Massive production keratinaceous byproducts in the form industrial wastes throughout world necessitates its justified utilization. Chemical treatment keratin proclaimed as an eco-destructive approach by various researchers since it generates secondary pollutants. Keratinase released a variety microbes (bacteria fungi) can be used for effective waste. Microbial degradation emerging eco-friendly offers dual benefits, i.e., recalcitrant pollutant (keratin) procurement commercially important enzyme (keratinase). This study involves isolation, characterization, potential utility fungal species chicken-feather through submerged solid-state fermentation. The isolated fungus was identified characterized Aspergillus (A.) flavus. In trial 30 days, appeared that 74 8% weight reduced sub-merged fermentation, respectively A. pH growth media fermentation changed from 4.8 to 8.35. exploited application keratinolytic is, therefore, recommended achieve benefits remediation.
