The aim of this study is to elucidate the structure and investigate the antimicrobial activity of an ulvan obtained by water extraction from green seaweed Ulva reticulata collected at NhaTrangsea of Vietnam by using IR, NMR, SEC-MALLS and SAXS methods. The ulvan is composed of rhamnose, galactose, xylose, manose and glucose (mole ratio Rha: Gal: Xyl: Man: Glu=1:0.12:0.1:0.06:0.03), uronic acid (22.5%) and sulphate groups (17.6%). Chemically structural determination showed that the ulvan mainly composed of disaccharide [4)-D-GlcA(14)-L-Rha3S-(1]. The results from SAXS indicated that ulvan under study has a rod-like bulky chain conformation. Ulvan from U.reticulata showed high antimicrobial activity, with inhibition zone diameter of 20mm against Enterobacter cloace and 18mm against Escherichiacoli. [GRAPHICS] .
