Abstract

Vitamins B6 and B12, biotin, folates, riboflavin, nicotinate, pantothenate, biopterin, and vitamin C (l-ascorbate) were assayed in Poteriochromonas stipitata, Euglena gracilis, and Tetrahymena thermophila cells grown in defined media and in spent culture supernatants. P. stipitata and E. gracilis synthesized, stored and excreted folates (mainly as 5-methyltetrahydrofolate), B6, riboflavin, pantothenate, nicotinate, biopterin, and ascorbate. E. gracilis synthesized and stored biotin. T. thermophila did not synthesize the above vitamins except for B12, biopterin, and ascorbate; it excreted biopterin and stored B12 and ascorbate. Thiamin was left of consideration because all 3 organisms are thiamin auxotrophs. Possible ecological implications of these findings are considered.
