Keratinolytic microbiome had ponderous application. Poultry waste degradation, composting and potential cast down of beta amyloid precursor and prion proteins were major hallmarks of keratin degrading microbe. Certain microbe, fungi having photolytic and hydrolytic action degrade the long chain cross linking disulphide bond of keratin present in animal hair, nails, hoofs and feathers. Gram positive bacteria proved to be major potential degrader as compare to gram negative bacteria. The poultry feather dumped soil were collected from the ICAR centre for NEH region, Lamphelpat, Manipur and characterised for the detection of various unicellular prokaryotes and multicellular eukaryotes which prove to have potential biotechnological Mecca. The isolate identified as be gram positive Bacillus shows maximum degrading potential. Single gram negative bacteria with least relative keratinolytic activity identified as Stenotrophomonas lamphella had been isolated. The relative action measuring the keratinase activity of isolate recorded predominant Bacillus the most having greater keratinolytic action as compare to the stenotrophomonas.
Key words: keratinase, Bacillus, keratinolytic, feather degradation, relative action
