Abstract

Our effort in discovering new valuable organism, A newly bacterium was isolated from chicken feathers enriched soil. Microscopic and biochemical study as well as 16S rRNA gene analysis identified the bacterium as Pseuodomonas aeruginosa. Microbial growth study confirmed its capability to use chicken feathers as a sole carbon and nitrogen source which reflects its capability to produce keratinase. Keratinase activity was measured in five consecutive days during incubation and it exhibited highest activity at second day, while chicken feather weight left is about 47 % and after five days and tyrosine concentration increased during growth. Chicken feather hydrolisate contains eighteen amino acids at various concentration (two amino acids were not determined) which potential for further application such as fertilizer and animal feed. Application of keratinase crude extract in goat-skin dehairing also showed potential application in tanning industry
