Encapsulation techniques and materials, explored for addressing compromised probiotic gut survival, report significant production losses resulting in <10% entrapment. Presently, we report three-time enhanced entrapment (30 ± 1.2%) of (LAB) in calcium-alginate beads, by modifying process parameters and employing polyethylene glycol (PEG). Water-loving, viscolysing and osmotic-building effects of PEG create numerous, fine voids in the alginate gel allowing efficient diffusion of crosslinking calcium ions, resulting in less leaky beads. Eudragit S100 overcoat improved LAB survival by 690 times in simulated GIT stresses.In DMH-DSS induced colitis and precancerous lesions in rats, while free LAB failed to show any protection, pharmabiotic beads significantly ( < .05) reduced lipid peroxidation, increased antioxidant levels; decreased serum inflammatory burden; downregulated , , and expression; elevated levels of the selected gut bacteria and SCFAs especially butyrate, all of which add up to antioxidant, anti-inflammatory, balanced gut biota, and ultimately anticancer effects.

Chinese yam polysaccharide (CYP) is an effective immunostimulant, however, its efficacy in grass carp, an important commercial fish species in Asia, remains untested. Here, our study evaluated the immunostimulatory effects of CYP on IgM B cells in vitro and on humoral immunity and immune defense against Aeromonas hydrophila infection in vivo. In vitro stimulation experiments showed that CYP could induce the secretion of IgM antibodies, because it could stimulate the proliferation and differentiation of head kidney IgM B cells.

Type 2 diabetes mellitus (T2DM), a serious metabolic disorder, is a worldwide health problem due to the alarming rise in prevalence and elevated morbidity and mortality. Chronic hyperglycemia, insulin resistance, and ineffective insulin effect and secretion are hallmarks of T2DM, leading to many serious secondary complications. These include, in particular, cardiovascular disorders, diabetic neuropathy, nephropathy and retinopathy, diabetic foot, osteoporosis, liver damage, susceptibility to infections and some cancers.

Microorganisms synthesize diverse types of exopolysaccharides (EPSs). EPSs with varying structural and physical properties can demonstrate unique health benefits, which allow for their tailored applications as functional foods such as prebiotics. Levan, a fructose-based EPS, is gaining considerable attention as an effective prebiotic to support the growth of beneficial gut bacteria.
