Presently, exopolysaccharide (EPS), due to its exceptional biological features is used as an efficient biopolymer. Therefore, the present study aimed is the EPS production by Lactobacillus Plantarum S123, its biopotential investigation and technological functional characterization. The results of microscopic examination suggested that the S123 EPS has a major portion of amorphous spongy like structure with partial crystalline nature. The FTIR and NMR results suggested that the S123 EPS consists on carbonyl and hydroxyl group respectively. Furthermore, the results of biopotential investigation suggested that the S123 EPS exhibited excellent antimicrobial activity against Gram’s positive (7.2mm) and Gram’s negative bacteria (11.5mm), DPPH radical scavenging activity (> 65%), water holding capacity (326.6 ± 0.5%), oil holding capacity (995.3 ± 0.2%), flocculation (89.5 ± 0.6%), and emulsifying (80.1 ± 1.1%) activities. Overall, the present results suggested that due to highly porous structure, efficient biotechnological potential the S123 EPS from Lactobacillus plantarum S123 can be used in the functional food product.
