Summary
Four polysaccharide fractions were obtained by acid and alkaline degradation of purified cell walls of Prototheca spp. and Chlorella spp. These fractions were further hydrolyzed and the component sugars identified. Five Prototheca strains and two Chlorella protothecoides strains have essentially similar polysaccharide compositions, which significantly differ from those of C. vulgaris and C. pyrenoidosa. This emphasizes the close affinity of C. protothecoides to Prototheca spp. not shared by other Chlorella spp.
