title: Feather degradation by Bacillus sp. FK 46 in submerged cultivation.
abstract: Cultivation conditions affecting feather degradation by Bacillus sp. FK 46 were investigated. The results showed that feather was almost completely degraded under the following conditions: 1% whole chicken feather as a substrate at the initial medium pH of 9 with 5% bacterial inoculum, at a temperature of 37 degrees C and a shaking speed of 250 rev/min. Glucose, methanol, Tween 80 and Triton X-100, however, had no effect on feather degradation. After feather was degraded, its residue and fermented broth would become a protein feed for animals.
