Lactiplantibacillus paraplantarum strain:Lactobacillus Genome sequencing

Lactiplantibacillus plantarum stands as one of the most prevalent culprits in beer spoilage. During production, it often persists in the guise of biofilm and can transition to a viable but non-culturable (VBNC) state triggered by environmental stressors. This transition has the potential to alter the beer's flavor profile and compromise its biological stability, ultimately leading to significant economic losses.In this study, we zeroed in on L. plantarum, a notorious beer-spoiling bacterium. We developed a culture model to simulate the conditions that induce the formation of membrane cells and investigated the intricate rules governing the induction and resuscitation of these cells into the VBNC state, particularly under the stress of high concentrations of isomerized hop extracts. Additionally, we delved into the impact of AI-2 on the biofilm formation capabilities associated with the VBNC state.
