Studies on the Cell Wall ofChlorellaV. Comparison of the Cell Wall Chemical Compositions in Strains ofChlorella ellipsoidea

摘要

Cell walls of four strains ofChlorella ellipsoidea(IAM C-27, C-87, C-102 and C-183) were compared as to their chemical compositions. Many differences were found:(1) The sugar composition of alkali-soluble cell walls differed in quantity as well as quality with glucuronic acid being found only in C-27 and C-87.(2) In alkali-insoluble cell walls glucosamine was found only in C-27. The other three strains contained mainly glucose.(3) The amino acid compositions of the alkali-insoluble cell walls markedly differed among the four strains. The cell wall of C-102 contained more amino acids than carbohydrates, but C-27 and C-87 contained extremely little amino acid.In addition to the variation in cell wall composition, the optical anisotropy findings also differed for these cell walls ofChlorellastrains which had been grouped as the same species.
