Volumetric lipid yield and starch content of the wild-type strain, strain PK4, and AATPL1-knockout strains under continuous light conditions. a Volumetric lipid yield [volumetric biomass yield × lipid content]. b Starch content in percentage of dry weight biomass (w/w). Bars represent standard deviations of the data from three independent samples. Statistical significance of differences between the values of strain PK4 and those of other strains or between the values of the wild-type strain and those of other strains were tested by Student’s t test (two-tailed), and the results are shown in Additional file 7: Table S3
