Effect of rapamycin on lipid content and biomass: Total lipid content (triangle) and dry biomass (circle) of T. oleaginosus after 72 h of cultivation in YPD are measured with different concentrations of rapamycin supplementation between 0 and 40 μM. Error bars show standard deviation and the star shows significance at p = 0.05 in comparison to culture without rapamycin supplementation. The blue line shows a robust logarithmic fit of the lipid content in dependence of rapamycin concentration as described in Additional file 1
