Lipid content (% w/w) in cells from fermentations performed in month-1 and month-7 estimated using standard curves obtained at month-1 (M1) and month-7 (M7), respectively. Curves based on IE (fluorescence emission intensity) (A, D), AE (fluorescence emission area) (B, E) and фfl (fluorescence quantum yield) (C, F). *G: lipids in cells grown in glucose media; *V: lipids in cells grown in VFAs-rich media
