Abstract :
Yakult is a popular probiotic drink that contains a specific strain of beneficial bacteria called Lactobacillus casei Shirota. It was developed in Japan by Dr. Minoru Shirota in the 1930s and is known for its potential digestive health benefits. The increase of antimicrobial resistance has required the exploration of other bio-therapeutic agents. The capacity of lactic acid bacteria (LAB), which are well-known for their probiotic qualities, to generate antimicrobial chemicals has made them attractive candidates. This study examined the antibacterial activity of LAB strains that were isolated from the commercially available probiotic health drink Yakult against a number of pathogenic pathogens, such as Salmonella typhi, Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli. De Man, Rogosa, and Sharpe (MRS) medium was used to cultivate the isolates, and their morphological and biochemical traits were used to identify them. The agar well diffusion method was used to measure antimicrobial activity.
