Investigation into optimizing fermentation processes to enhance uric acid degradation by probiotics
To enhance the activity of Lactiplantibacillus plantarum FS4722 ( L. plantarum FS4722 ) in reducing uric acid, this study optimized the culture medium components and fermentation conditions using response surface methodology. The results indicated that the optimal culture medium comprised glucose at 25.61 g/L, yeast extract powder ( YEP ) at 26.86 g/L, and nucleoside addition at 0.48 g/L. The optimal fermentation conditions were: a fermentation time of 10 h, an initial pH of 6.5, a fermentation temperature of 33 °C, and an inoculum size of 1.0 %. Under these conditions, the nucleoside degradation ability of L. plantarum FS4722 increased by 41.9 times, enhancing its potential applications in reducing uric acid and developing anti-gout foods, health supplements, and pharmaceuticals.
