[a] The values for the 1 mL batch and the BCR after cultivation under the same conditions were taken from Ref. [5]. [b] Calculated from the dimensions of the BCR but not considered for comparison, since the actual irradiated surface area is higher for this reactor due to the internal illumination principle adopted, but it could not be determined.
