Extracellular products from Chlorococcum ellipsoideum and Chlamydomonas globosa

Summary Extracellular products of Chlorococcum and Chlamydomonas were isolated from culture filtrates. Five groups of substances were found in both species: (i) steam-volatile acids, (ii) yellow water-soluble phenolic compounds, (iii) lipophilic substances, (iv) proteins and (v) polysaccharides. Chlorococcum had higher concentrations of all groups than Chlamydomonas; moreover, the two species differed slightly in the composition of groups (ii) and (iii). Probably, these is a great similarity between green algae in the production of extracellular compounds.
