Characteristics and Use of Yellow Stripe Trevally Hydrolysate as Culture Media

Characteristics and the use as culture media of protein hydrolysate from yellow stripe trevally (HF(25)) were determined in comparison with Bacto Peptone. HF(25) had the higher contents of ash (45.73%), lipid (0.77%), and moisture (4.34%) but lower protein content (42.11%) than did Bacto Peptone (P 0.05). Thus, the conversion of low market value species to fish protein hydrolysate, which can be used as the nitrogenous substrate for microbial growth, could be achieved.
