Abstract :

Keratinases produced from the keratin degrading bacterial isolates were isolated from feather compost soil. Bacillus sp. was isolated poultry compost in the poultryfarm. Among 6 isolates, 2 Bacillus isolates showed notable keartinolyticactivity which the highest was observed by Bacillus sp. KB–4 and KB–5, which wereidentified as Bacillus licheniformisKB–4 and Bacillus subtilis KB–5 respectively.Both isolates, the maximum keratinase production occurred at 1% concentration offeather meal with starch as carbon source at pH–7, 35°C to 40°C for 6 days. Innitrogen source, the maximum amount of enzyme production was achieved withpeptone for B. licheniformisKB–4 and with yeast extract for B. subtilis KB–5. B.licheniformisKB–4 isolate rapidly utilized feather as nutrient source and multipliedmaximum when compared with B. subtilis KB–5. B. licheniformisKB–4 isolatedegraded the feather up to 43.72% on 5 days incubation and B. subtilis KB–5was36.26%. Based on all experiment B. licheniformisKB–4 isolate showed better resultand it was considered as an efficient isolate for feather degradation.
