A factorial experimental design in which the concentration of Bacillus (2, 3 and 4 g / L) and substrate (15 and 18%) was varied was performed. This process is performed in the aerobic fermenter type Bach at room temperature ( 25 ° C), pH (7.5) was adjusted. In preparing the cream hydrolyzate concentration (47, 60 and 73 %) it was varied. By spectrophotometry UV-Visible nitrogen content it was determined, obtaining 3.28% obtain keratin hydrolyzate, which is concentrated to be deodorized up to 10%, and a room temperature for incubation. Showing that this hydrolyzate is an advisable for the preparation process of concentration based relaxer. |
