Chlorophyll a synthesis in unicellular green, unicellular and colonial blue-green algae was simulated by moderate concentrations of both alkaloids used (solasodine and diosgenin). Chlorophyll b as well as carotenoids production was enhanced by lower concentrations of solasodine than diosgenin.
Phycobilins (phycocyanin and phycoerythrin) pigment production stimulated by lower solasodine and moder...
