An Updated Review on Probiotic Production and Applications

Microorganisms are ubiquitous and have been exploited for centuries to generate primary and secondary metabolites essential for human welfare and environmental sustainability. Microorganisms occupy a prominent position in the industrial sector due to their unique properties, such as the limited time and space required for their growth and proliferation, as well as their easy manipulation of the genetic material. Among all the microorganisms, probiotics have grabbed the attention of researchers because of their nonpathogenic nature and immersive application in treating digestive ailments and vitamin deficiency, boosting immunity, and detoxifying harmful chemicals. Furthermore, probiotics are widely used to treat various diseases such as constipation, colon cancer, type 2 diabetes mellitus, and obesity, as well as a range of intestinal disorders, including inflammatory bowel disease, among others. The updated information on these diseases and the role of probiotics has not been updated in the past few years. The present review covers updated information on the role of probiotics in these topics. The growth of populations around the globe has attracted the attention of scientists, primarily investigating diverse technologies to meet the gap between probiotic production and demand. With the support of standardized tools and techniques, researchers have explored the potent probiotic strains feasible for industrial production and treating health ailments. In the current review, we have curated the potential information essential for the screening, strain selection, production, and application necessary for probiotic researchers.
