Relative percent of heptadecane and FAMEs extracted from whole cells (a), or from lipid droplet enriched fraction and debris pellets from exponentially grown (b) or stationary (c) phase cultures. FAMEs and heptadecane obtained from cell pellet fraction or whole cells (light gray) and isolated LDs (dark gray). Lipids were extracted from MA grown culture during exponential growth or from late stationary phase cultures initially grown in MA that had transitioned to nitrogen-fixing growth (n=3).
