Photoinactivation of Ichthyrotoxin from Axenic Cultures of Prymnesium parvum Carter

I. Parnas1, K. Reich and F. Bergmann

Department of Zoology, The Hebrew University, Jerusalem, Israel

ABSTRACT

The ichthyotoxin of Prymnesium 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.
