Preserving probiotic potency: A comparative study of storage methods for Lactobacillus fermentum MT308789 And Lactobacillus oris MT308790

Probiotics, comprising living microorganisms like Lactobacillus fermentum MT308789 and Lactobacillus oris MT308790, offer significant health benefits when consumed regularly. However, the efficacy of probiotics heavily relies on their viability and stability during storage. Various storage methods, including agar slant, glycerol stocks, lyophilization, and dry form, are utilized to preserve probiotic viability. In this study, we evaluated the efficacy of these storage methods in maintaining the viability of probiotic strains. Our findings demonstrate that lyophilization emerged as the most effective method, yielding the highest viabilities for both strains [77.51 %]. Glycerol stocks also showed promise for short-to-medium-term storage, while agar slants and dry form storage exhibited suboptimal viability. These results underscore the importance of selecting appropriate storage methods to ensure the delivery of viable and effective probiotic formulations to consumers.
