dc.description.abstract | Th e protein content of little tuna viscera as well as tuna meat has great potential to be used as peptone. Th e aims of this research were to produce peptone from little tuna viscera using papain enzyme and then test it for bacterial growth. Th e optimal concentration of papain used to hydrolyze little tuna viscera protein was 0.26% for 3 hours. Little tuna viscera peptone produced had water content 7.66%; ash 2.34%; protein 50.18%; and fat 0.47% with the highest and lowest amino acid were glutamic acid (6.38%) and cysteine (0.68%), respectively. Th e peptone had solubility of 98.20%; total nitrogen of 8.03%; free α-amino nitrogen1.12%; ratio of free amino acid and nitrogen total 13.93%; salt content of 0.79%; range of yield was 3.92 to 5.54% and pH of 6.02. Furthermore, little tuna viscera peptone could be used on luria broth (LB) for medium of Escherichia coli and Staphylococcus aureus growth. Specifi c maximum growth rate of E. coli on medium using little tuna viscera peptone was higher than commercial peptone, whereas the specifi c maximum growth rate of S. aureus on medium commercial peptone was lower than the little tuna viscera peptone. | id |
