Structure characterization of novel heteropolysaccharides from Pteridium revolutum with antioxidant and antiglycated activities

Exopolysaccharides from Enterococcus faecium and Streptococcus thermophilus: Bioactivities, gut microbiome effects, and fermented milk rheology

“…The hydrogen peroxide scavenging activity was 10 % and 11 % for EPS-LB13 and EPS-MLB10, respectively, whereas the hydroxyl radical scavenging activities were 86 % and 82 %, respectively, at 250 mg/L EPS, which were higher than those of the EPS isolated from S. thermophilus GST-6 ( Xu et al, 2023 ) and E. faecalis ( Choudhuri et al, 2020 ). Our results are comparable to antioxidant activities reported by Wang et al (2023) , who characterized heteropolysaccharides from Pteridium revolutum . The ability of purified EPS to inhibit oxidative stress caused by the chelation of metal ions and lipid peroxidation was also measured.…”
