Deskripsi

Keratinolytic microorganisms have the capacity to biosynthesize particular keratinases and their prospective application in poultry waste management. The objective of this study was aimed to utilize keratinolytic microbes for the degradation of poultry’s waste. For this purpose feathers of common ostrich(Struthiocamelus) were collected along surrounding dry soil from aprivate ostrich farm, Kasur located near Lahore, Pakistan. Bacteria were isolated by using enrichment culture techniques and screened for their proteolytic activity on skim milk agar. The isolates were characterized colonially, morphologically and biochemically and named as SNO1, SNO2 and SNO3. The effect of differentpH and temperatures were recorded on bacterial growth and feather degradation.It was noticed that the bacterial cell densities and feather degradation were high at temperature 50˚C and pH 8.0 as compared to the rest of the culture conditions.Visual observations were madeusing a stereomicroscope. The maximum feather degradation in the form of white powdery mass was noticed at 4th week. The protein content of Struthiocamelusfeathers wasdetermined as 6.5 mg/100 ml after degradation.Taken together research finding concluded that the isolated strains have the capability for feather degradation and can be used in poultry waste management that is hot issues in the poultry industry.
