Implication

Randomized trial demonstrates reduced bacterial contamination in fish using phage and nisin, suggesting improved food safety.

Key Points

This study aims to evaluate the antibacterial effects of microencapsulated bacteriophage P-2FD combined with nisin against Pseudomonas psychrophila in refrigerated grass carp.
Phage-loaded microspheres were created using 2.2% alginate and 2% calcium chloride.
The antibacterial effects were tested on artificially contaminated fish blocks over six days.
Total bacterial counts and total volatile basic nitrogen (TVB-N) levels were measured for food safety assessment.
Total bacterial count decreased by 2.48 log 10 CFU/g at day 6 in the treated group compared to control.
Control group reached a TVB-N value of 22.68 mg/100g, exceeding food safety limits.
TVB-N value in the experimental group decreased by 9.79 mg/100g, indicating improved food safety.
