Abstract

A culture of the thermophilic, unicellular, blue-green alga Synechococcus lividus was freed from two thermophilic bacteria by use of equilibrium (isopycnic) centrifugation in Ficoll density gradients. After removal of the bacteria, the alga would grow only on agar plates in a high carbon dioxide atmosphere. Intermittent illumination, equilibrium centrifugation, and differential centrifugation were tested as techniques for obtaining synchronized cultures of the alga. Daughter cells selected by differential centrifugation in Ficoll density gradients yielded the best synchrony, and a cross-wall index of 85% was observed during the period of cell division.
