Extended Data Fig. 1: Quantitative analysis of cellular lipid content in cultured samples.

Quantification of cellular core lipids content in isoprenoid glycerol dibiphytanyl glycerol tetraethers (IPL-derived CLs) following acid hydrolysis over a harvest time of 120 days. The dashed lines indicate the lower and upper bounds (0.7 and 1.5 fg/cell, respectively) for the estimated cellular lipid content derived from a cellular geometry model. Bathyarchaeia biomass was additionally quantified using quantitative PCR (qPCR).
