Antioxidant and immunomodulatory activity of selenium exopolysaccharide produced by Lactococcus lactis subsp. lactis

Isolation, purification and characterisation of selenium-containing polysaccharides and proteins in selenium-enriched Radix puerariae

“…The relatively strong absorption peak at 1640 cm −1 indicated the characteristic of CO. The absorption peak at 660 cm −1 indicated the characteristic of SeO.…”

“…The result was confirmed by selenium exopolysaccharide produced by Lactococcus lactis subsp. lactis indicated SeO 3 2− …”

Antioxidant activity of phosphorylated exopolysaccharide produced by Lactococcus lactis subsp. lactis

“…In our previous research, we reported that selenium exopolysaccharide produced by Lactococcus lactis subsp. lactis showed higher antioxidant and immunomodulatory activity than EPS (Guo et al, 2013). With further development, P-EPS could be used as a new antioxidant in the food and pharmaceutical industries.…”

Antioxidant and antitumour activities of exopolysaccharide from liquid‐cultured Grifola frondosa by chemical modification

“…After centrifugation, the supernatant was dialysed (molecular weight cut‐off 7.0 kDa) using distilled water for 72 h. The polysaccharide solutions were concentrated and frozen. The Se content of Se‐EPS was determined by standard curve method using Na 2 SeO 3 as a standard based on the previous method (Guo et al ., ).…”

“…Recently, many studies have demonstrated that chemical modification of polysaccharides including carboxymethylation and selenylation exhibited greater biological activities than native polysaccharides (Guo et al ., ). Selenium (Se) is an essential element for nutrition of a capital importance in the human biology.…”
