Abstract

Cellulose has been characterized from isolated cell walls of the conchocelis phases of both Porphyra umbilicalis and P. leucostricta. Evidence for cellulose II (regenerated cellulose) in Schweitzer's reagent extracts was provided by X-ray powder analysis and paper chromatography of partial hydrolyzates. The presence of cellulose in the conchocelis phase of species of Porphyra provides evidence for the continuity of cell wall composition within the Rhodophyta. Adoption of a classification scheme incorporating consolidation of all red algal orders under the single class Rhodophyceae is proposed.
