Abstract

In the current study abilities for the mixotrophic growth of phototropic cave strains were observed. The influence of organic substrates on the growth rate on Chlorella vulgaris, Stichococcus bacillaris, Leptolyngbya foveolara, Scytonema were studied. In most cases glucose, maltose, glycerine, malate, acetate, sucrose, and peptone showed a stimulating effect on the culture growth rate by the dark and by the light incubation. Specific abilities for mixotrophic carbon consumption were proved.
