The effect of Nostoc punctiforme akinete germination on hopanoid localization. A. Physiological changes in membrane architecture that accompany the germination process. The white arrow indicates cell envelopes that have been jettisoned from cells. B. Chromatograms of the 205 Da ion from the total lipid extracts of 6-month-old akinetes, cells collected 48 hours after germination was initiated, and jettisoned akintete envelope as indicated. Lipid analysis was performed on a DB-XLB column as indicated in the methods and hopanoid structures are identified in the figure by their respective numbers (see Figure 1).
