Nature Of The Aflatoxin B, - Induced Inhibition Of Photosynthesis In Chlorella Fusca (Chlorococcales, Chlorophyta)

Abstract

Treatment with Aflatoxin E^ (AFBi) resulted in inhibition of photosynthetic oxygen evolution in Chlorella fusca Shih.et Krauss. Treatments also induced a marked reduction of both chlorophyll and carotenoid contents. Inhibition of photosynthesis was manifested by loss of the variable component of Chlorophyll a (Chi a) fluorescence induction kinetics. Results are discussed in terms of the observed AFB, - induced ultrastructural disorders at the level of the chloroplast thylakoid membrane.
