Production Optimization of Feather Hydrolysate and Use as a Promising Nitogen-Rich Fertilizer for Rice (Oryza Sativa) Production

Abstract

Present agriculture sector mostly depend on synthetic fertilizer for better crop. Feather is a rich source of protein and nitrogen. It was degraded by Keratinolytic bacteria Bacillus wiedmanni SAB10 in poultry litter sole media. Feather hydrolysate was produce from solid state fermentation process and fermentation condition was optimized through OVAT (One Variable At A Time) system. In this process feather (1.25%w/v) was fully degraded in poultry litter(1%w/v) with in 48 hrs at pH 10.After the fermentation cell free feather hydrolysate use in rice plant in different concentration and different mode. Liquid feather hydrolysate produced from solid state fermentation contain important amount of protein (3.12mg/ml) and amino acid(792µg/ml) that enhances the rice plant growth in pot trial condition. After application Group D Plants leaves have been reported to have higher levels of total chlorophyll (5.25mg/g of dry wt), IAA (17.23µg/ml)..Carbohydrate contain of rice has increased 1.6 fold than control Following the spraying of feather hydrolysate (300 µl/ml), the phenolic (1.71 fold) and flavonoid (1.52 fold) contents significantly increased.. The novelty of our investigation is we use here two wasted products and convert them a valuable product.
