Feather waste degradation by keratinophilic fungi: An alternative source for protein and aminoacids

Jitendra Kumar, Pankaj Kumar and R. K. S. Kushwaha

Two hundred thirty four fungi obtained from various habitat of Kanpur are used for estimation of protein release and amino acids in submerged state fermentation. Considerable amount of protein is released by Chrysosporium tropicum, Penicillium griseofulvum and Aphanoascus terreus, 432.66 μg/ml, 359.33 μg/ml and 339.66 μg/ml respectively. Maximum amount of lysine and cysteine was released by Acremonium strictum 18.00 μg/ml and 32.00 μg/ml. Pea plant supplemented with degraded feather showed better growth. Application of feather waste as slow nitrogen fertilizer may improve disposal as well as environmental clean-up.
