Trans-Cinnamic acid is a natural antimicrobial with a minimal inhibitory concentration (MIC) of 250 μg/mL against the fish pathogen A. sobria, SY-AS1. It shows moderate inhibition on rainbow trout intestinal isolates A. sobria SY-AS3 and S. baltica, SY-S145, gill isolate F. spartansii SY-FS1, and fish pathogens A. salmonicida ATCC 33658, Listonella anguillarum, SY-L24, V. crassostreae SY-VC10, and Y. ruckeri E42. This acid is more effective on bacteria when the pH of the culture media is not neutralized. It also inhibits M-CSF/RANKL-induced osteoclast differentiation in C57BL/6 mouse bone marrow macrophage with an IC50 > 100 μM.
