The ichthyotoxin ofPrymnesium parvum is inactivated by visible (400 to 510 mμ) as well as by ultraviolet light (255 mμ). The changes in the absorption spectrum of purified (pigment-free) ichthyotoxin during this process indicate that different mechanisms may be involved in the inactivation by visible or ultraviolet light. Photoinactivation is not affected by the presence of cells, cell pigments, oxygen, or glutathione.
