On heterotrophic nutrition of some species of green algae

Abstract
The growth of eight species of green algae on sixteen organic substrates in the light as well as in the dark was tested quantitatively. The growth was stimulated by most organic substrates and we can correlate it with heterotrophic nutrition. The heterotrophic growth was stimulated in the light. The best ability of heterotrophic growth has been shown in two species: Scenedesmus quadricauda and Chlorella sp., and the poorest in Ulothrix sp. Glucose, fructose, peptone and yeast extract were the most efficient growth substrates and the least efficient were ribose and urea.
Enlarged and giant cells of unicellular species were usually present during their heterotrophic growth. These changes are considered to be the consequence of the disharmony between the process of cell growth and cell division.
