Capsular Polysaccharides of Lactobacillus spp.: Theoretical and Practical Aspects of Simple Visualization Methods.

Lactobacillus strains can synthesize capsular polysaccharides (CPS), which are important substances in the dairy industry-they exhibit many important technological as well as health-promoting properties. Technological advancements have made it possible to detect bacterial capsules using costly and labor-intensive methods, such as serological reactions, molecular genetic techniques, and electron microscopy. Light microscopy, which is the method of interest in this paper, is one of the most widely accessible and cheapest techniques.

Exopolysaccharides produced by Lactobacillus sp.: Biosynthesis and applications.

Lactobacillus sp. synthesize exopolysaccharides (EPS), including both homo- and heteropolysaccharides, which play an important role in the production of fermented foods, and especially in the dairy industry, improving the gustatory and rheological properties of the finished products. These polymers are generated by starter cultures in situ in fermented foods, and so they are treated as natural thickening agents.

The use of Yucca schidigera and microbial preparation for poultry manure deodorization and hygienization.

The aim of this study was to determine the effectiveness of microbial preparation and Yucca schidigera in the removal of odorous volatile compounds from poultry manure as well as to evaluate antimicrobial properties of these amendments. It was demonstrated that the combined treatment of poultry manure (PM) with the microbial preparation and Y. schidigera extract can reduce the concentration of odorants by 58%-73%, depending on the tested compound.
