This review explores the diverse applications and health benefits of probiotic lactic acid bacteria (LAB) through biotechnological applications in the food industry. While all LAB are indispensable for the production of fermented foods thanks to their ability to produce lactic acid and bacteriocins that act as natural preservatives, specific strains of probiotic LAB offer targeted health benefits. In addition to general benefits of LAB, probiotic strains significantly enhance gut microbiota, enhance human immunity, and exhibit antimicrobial properties. This review also delves into the mechanisms of action of probiotic LAB, focusing on adhesion, colonisation, and antioxidant production, emphasising their potential to advance nutritional innovations. Beyond food production, the broader category of LAB has transformative potential in industrial applications, particularly in the sugar industry, where their metabolic activity can improve sucrose extraction processes, promote microbial management, and reduce unwanted by-products. By understanding these aspects, the review underscores the importance of probiotic LAB in promoting health, efficiency, and sustainability across sectors.

The development of separation technology based on continuous simulated moving bed chromatography in sugar technology is described. This is a potential economic alternative method both in terms of separation efficiency and process performance, and in terms of the high purity of the resulting products. This work focuses in detail on the isolation of mannose from natural polysaccharides, such as galactomannans; however, the developed procedures and equipment can be further applied to the separation of various liquid mixtures of carbohydrates. The main aim was to find optimal operating conditions for hydrolytic and separation steps of the whole technology. The obtained results provide a basic data set for further development of the industrial application.
