A thermotolerant Streptomyces graminofaciens was isolated which could digest chicken feather at 40 C very efficiently. The majority of the fragments produced during feather digestion was in the range of colloid particles or even smaller. The maximum amount of feather in the medium which could be digested in 1 week in submerged culture was 10%. The procedure did not require previous mechanical disruption of the feather which makes the application fast and easy.
