| Popis: | The objective of this research was hydrolyzed feather meal of chicken for the production of keratin. The methodological research design was experimental; four fermentations, corresponding to a completely randomized experimental design, resulting from considering factors [substrate concentration (18 g / L and 23 g / L) and concentration of inoculum (2 and 3 g / L), two levels was performed for each factor]. Determining the total nitrogen concentration was performed by UV-Visible spectrophotometry, the method used is the persulfate potassium digestion (K2S2O8), the maximum concentration of nitrogen is reached in the treatment 2 (1.5%) which multiplied by the factor protein 6.25 gives a percentage of 9.4% protein in the hydrolyzed keratin, showing significant difference (p |
