The concentration-dependent impact of quorum-sensing signal molecule 2-phenylethanol on the flavor metabolite profile of Lactiplantibacillus pentosus 1 in a simulated sour fish system
{{output}}
2-Phenylethanol (2-PE) is a quorum-sensing molecule that influences microbial metabolism, but its specific role in lactic acid bacteria (LAB) fermentation remains underexplored. This study investigated the effects of 2-PE (0-750 μM) on Lactiplantibacillus pen... ...
