In recent years, interest in postbiotics has grown due to their potential health benefits and applications food systems. This study evaluated various nutritional sources for lactic acid bacteria (LAB) fermentation enhance postbiotic production. Three LAB strains were tested: Pediococcus acidilactici CECT 9879 (PA), Weissella cibaria 30731 (WC), Lactococcus lactis 30734 (LL). Fermentation experiments assessed bacterial growth, pH levels, antibacterial activity against E. coli using different carbon nitrogen sources. Fructose xylose significantly improved growth WC (9.39 ± 0.16 log CFU/mL) LL (9.37 0.22 compared glucose. Ribose enhanced antimicrobial PA (41.67 2.89%) (50.00 0.00%) relative Additionally, plant-based sources, such as soy (LL: 8.93 0.12 CFU/mL 81.67 wheat (WC: 9.40 0.17 65.00 0.00%), along with microbial like yeast (PA: 9.57 40.00 effectively supported activity. These findings highlight the of developing animal-free media that meet nutritional, safety, sustainability criteria while making a significant contribution optimization
