Newman, Tony C. Davidson] Solid-state 13C nuclear magnetic resonance (NMR) and wide-angle X-ray scattering (WAXS) were used to characterise the cellulose in six species of Florideophycean algae. NMR identified cellulose Iβ as the dominant crystalline form in all species, and was used to estimate the widths of the sheets of cellulose chains. The mean value (±SD) was 3.9±0.4nm. WAXS was used to estimate the thickness of microfibrils measured normal to the sheets of chains. The mean value (±SD) was 1.9±0.5nm. Uniformity of these results across the six species supported a generalisation that Florideophycean algae biosynthesise cellulose chains in microfibrils that are narrower than those biosynthesised by Bangiophycean algae. ©2004 by Walter de Gruyter Berlin New York Hydrobiology nationallicence Mycology, fungi nationallicence Botany & plant sciences nationallicence 13C NMR nationallicence cellulose nationallicence Florideophyceae nationallicence microfibrils nationallicence X-ray diffraction nationallicence Newman Roger H.
