Structural Characterization and Immunological Activity of Polysaccharides Extracted from Ulva pertusa Fermented by Bacillus velezensis
Ulva pertusa polysaccharide is a sulfated heteropolysaccharide, but its high molecular weight has led to an unclear understanding of its bioactive mechanisms. In this study, a fermented polysaccharide, UBV-1, was obtained through cofermentation of U. pertusa powder with Bacillus velezensis, followed by separation and...
