The keratinolytic bacterium Bacillus cereus B5esz was applied to the biodegradation of pig bristles using two methods: a 24-h enzymatic digestion with concentrated culture fluid and a 10-day degradation under specific culture conditions. Prior to the degradation experiments, the effects of thermo-ch...
