Abstract:The exopolysaccharide (EPS) produced by Lactiplantibacillus plantarum is a high-value bioproduct in food and health industries, and its biosynthesis has been found as a secondary metabolic pathway to mediate acid stress. To quantitatively investigate acid stress response in L. plantarum and model EPS production, this study measured metabolomics, proteomics and growth data for L. plantarum HMX2 cultured at 4 different pH values. The growth and metabolomics data showed that under acid stress, the EPS production … Show more
