Fig. 8: Cell shape of T. kivui cells grown in glucose-limited chemostats at different growth rates.

For reference, data from exponentially growing batch cells (orange) are included. a cell length; b cell width; c cell volume; d surface area/volume ratio; e cell volume in comparison to other organisms; f representative microscopy images of T. kivui cells grown at 0.002 h⁻¹; g representative microscopy images of T. kivui cells grown at 0.07 h⁻¹. For (a–c), n = 39–1055 (Cellular dimensions are mean values of ≥39 cells measured from microscopy images as indicated in Supplemental Data 1), symbols indicate mean values, error bars indicate standard deviation. For (f–g), 25 microscopy images were acquired for each datapoint and representative images from the slowest and fastest growth rates are shown. Red, chemostats; orange, exponentially growing cells from batch cultures; green triangles, M. maripaludis²³; blue squares, E. coli³⁴. Source data are provided as a Source Data file.
