Abstract

Growth and pigment biosynthesis of Spirulina platensis Geitler, an edible cyanobacterium were stimulated at low concentration (1 mg/l) of Pb2+. The pigment biosynthesis was found to decrease with increasing Pb2+concentrations. The ratio between chlorophyll a and β carotene was constant regardless of the Pb2+concentration in the medium indicating that both are equally affected by Pb2+.  

Key words: Growth, Pb2+, Pigment biosynthesis, Spirulina platensis
