Abstract:In this study, transmission electron microscopy (TEM) and cryo‐scanning electron microscopy (cryo‐SEM) were evaluated for their ability to detect lipid bodies in microalgae. To do so, Phaeodactylum tricornutum and Nannochloropsis oculata cells were harvested in both the mid‐exponential and early stationary growth phase. Two different cryo‐SEM cutting methods were compared: cryo‐planing and freeze‐fracturing. The results showed that, despite the longer preparation time, TEM visualisation preceded by cryo‐immobi… Show more
