“…Crossed columns represent k L a values of the various culture systems. Black column represents the k L a range for 10 × 10 6 cells mL −1 with varying air saturation and the striped column represent the k L a values required for different cell densities at 40 % of air saturation – data taken from 13, 31, 65, 77, 83, 84, 99, 102, 122, 127–130 (supplementary dataset: DOI: https://doi.org/10.25375/uct.12263141).…”
