Recovery of the inhibited wax ester fermentation in anoxia by inorganic carbon sources.

The relative levels of C28 (14:0–14:0) are shown as representing the wax esters in E. gracilis Z. The cells were cultivated in the light under hypoxic and anoxic conditions in the presence of CO₂ and/or NaHCO₃ (either 10 mM or 20 mM). The inset indicates light-anoxic conditions without an exogenous carbon supply. Error bars indicate standard deviation from triplicate cultures.
