Ameliorating Effect of Plant Growth Promoting Bacterium Staphylococcus Sciuri Psd 11 Isolated from Feather Waste Dumping Site

Feather degrading bacterium was isolated from poultry waste dumping site. Total thirteen bacterial isolates were stipulated on the basis of their growth pattern on nutrient agar and screened for proteolytic activity. Among these, eight isolates exhibited casein hydrolysis and hence, exposed to feather degradation for keratinolytic ability. Studied strain having significant keratinolytic potential was explored for biochemical characterization as well as for molecular sequencing using 16S rDNA. Sequenced bacterium having maximal keratinolytic activity was characterized as Staphylococcus sciuri. S.sciuri exhibited 99.05 U/ml of enzyme activity on optimized media and it also susceptible to commonly used antibiotics (eg: Azithromycin). This bacterium was effective to customize feather waste into nutrient loaded hydrolysate and exploits as plant growth enhancer for tomato and black mustard plant. This potent microbe exhibited keratinolytic efficacy towards biotechnological and agricultural applications. Thus, isolated keratinolytic bacterium could be a potential agent for total degradation of feather waste and showed eco-friendly association with environment as it helps to reduce environmental pollution.
