HPLC Analysis of Carbohydrates in Two Red Tide Phytoplanktons (Chattonella antiqua and Heterosigma akashiwo)

Abstract

The composition of water-extractable cell wall and extracellular carbohydrates of Chattonella antiqua and Heterosigma akashiwo from the Seto Inland Sea were analyzed by high performance liquid chromatography. Both planktons produced the largest amount of carbohydrate in the stationary phase of culture. Polysaccharides (M. W. < 1500) were the major carbohydrates of both phytoplanktons.
