Additionally, CSP had strong anti-biofilm activities against LM by inhibiting the bacterial aggregation and the production of biofilm protein and polysaccharide. Moreover, CSP was found to suppress the growth of microorganisms, prevent protein degradation and lipid oxidation, delay moisture migration, and keep sensory properties of sea bass fillets contaminated with LM during storage at 4 °C for 7 days.
