An efficient keratinolytic strain of Stenorophomonas maltophilia KB13 was isolated from feather disposal site of Bilaspur, Chhattisgarh, India. The strain could metabolize 10 g/l chicken feathers as sole source of carbon and nitrogen. Soluble protein, amino acid, and cysteine content were found to be maximum (690.6 ± 8.7, 688.9 ± 9.12 and 21 ± 0.36 µg/ml, respectively) at late logarithmic phase...

Abstract In recent years, an increase in the chicken meat process industry has been growing quickly, which brings a large amount of difficult to waste, feathers. These billions kilograms create serious waste problem over world, furthermore, poultry feather processing is not only particularly but also relatively expensive. fact, there no technology suitable for such huge quantities feathers guar...

Feathers are the most prevalent agricultural waste generated by chicken farms, polluting environment and wasting protein resources as a result of accumulation large amounts feathers. Therefore, keratinase-producing microorganisms represent promising potential technique for degradation feather waste. Streptomyces netropsis A-ICA Bacillus subtilis ALICA, previously isolated from rhizosphere deser...
