Abstract

Protein hydrolysate (PH) from viscera of cultured Siberian sturgeon (Acipenser baerii) was produced. To optimize the production conditions, Response Surface Method (RSM) was employed to examine the effects of three different operating conditions, including time, pH, and enzymatic concentration (Alcalase) on the degree of hydrolysis. The mathematical model showed acceptable fitness of the experimental data as R2 equaled 0.97, which indicated that major part of the variability within the range of values could be explained by the model. The results showed that the highest degree of hydrolysis (58.21%) was related to the treatment which happened at the enzymatic concentration of 2%, 60 minutes time, and pH=8. Treatment under hydrolysis condition (i.e., E/S=2%, Time=45 min, and pH=8.5) had the highest protein content (42.37g/l), which was used as an alternative to commercial peptone medium (Triptic soy broth) to assess the growth of SALMONELLA TYPHI bacteria from 0 to 48 hours. Although there was an upwardtrend in growth rate of S. typhi both in control and No.15 (Alcalase) treatments, the log growth of control treatment was found to be better than that of ALCALASEtreatment. However, there existed no significant difference between the twotreatments.
