Preparation of Pure Blue–Green Algae

Abstract

IN the course of measuring the resistance of blue-green algae to γ-radiation from a cobalt-60 source, initially contaminated blue-green algae were found to be free from bacteria after irradiation. Since difficulties are encountered in the purification of Cyanophyta1 (less than 30 per cent of the organisms in the Indiana University Collection are bacteria-free2), γ-radiation may afford an easy, reliable method for purifying algae from bacteria and be of advantage in physiological and biochemical investigations of these organisms. Practical conditions for the purification of a group of typical Cyanophyceae were, therefore, determined.
