EXOPOLYMERS OF PROBIOTIC LACTOBACILLI AND BIFIDOBACTERIA (NEW APPROACHES AND FEATURES)

This paper summarizes the results of electrophoretic and other studies of exopolymeric substances (EPS) of probiotic lactobacilli and. bifidobacteria of human origin. It finds that EPS of lactobacilli were significantly less produced and. low stained with fluorescent dye compared to bifidobacterial ones. For the first time, the systems of biosurfactants of bacilli and. bifidobacteria were identified. Also the pictures of physical layer EPS gradients of bifidobacteria were described for the first time. Part of EPS included cationic latent biosurfactants. Perspective features of EPS are described. The used approaches are suitable for both screening probiotic producers of EPS and. monitoring EPS consumption or degradation. Electrophoresis in pore gels can be used for obtaining directed 3D gradients of EPS associated with (glyco)proteins and. (glyco)lipids
