In 2020, we reported a keratinolytic strain of Aquamicrobium defluvii for the first time......
This study assessed novel keratinolytic bacteria for feather valorization to yield feather hydrolysates (FHs) to cultivate vegetables. Bacterial degradation of feather was determined through production of keratinase. Corchorus olitorius (Jute mallow), Celosia argentea (Cockscomb), and Amaranthus caudatus (Pendant amaranth) were grown with FHs through soil-less and pot experiments.
