Bio-degradation of Feathers Waste by the Staphylococcus epidermidis P3A

Abstract

Development of industrialization is directly proportional to the development of nations. Rising industrializations also increase the pollutions. One of them is poultry industry which discharges a huge amount of keratinous waste. The present study focused on the selection of feather degrading bacteria from Barshi region of Maharashtra. Bacterial strains were grown in whole feather broth medium. Out of 16 proteolytic bacterial isolates, 9 feather degrading isolates were selected from the Parande road side feather waste dumping area. Among these isolates, P3A was selected and classified on the basis of morphological and biochemical analysis. 16S rRNA studies confirmed that the isolated strain was Staphylococcus epidermidis. Staphylococcus epidermidis P3A shows 84% feather degradation and 72 U/ml maximum keratinase activity after 96 hrs. The isolate shows potential use in feather waste disposal methods which are safe and environment friendly.
