Vitamin B12 requirement of a marine blue-green alga.
A species of Synechocystis isolated from a marine mud has an absolute requirement for vitamin B(12). Analogues of B(12), including cobinamide and alpha-(adenyl) cobamide cyanide, satisfactorily substitute for vitamin B(12). Methionine alone or in combination with other compounds supports only a low level of growth.
