Generally fungal fermentations are pseudoplastic. Hence in large reactors the cells
The principle of quantitative reasoning explains that ratio, percentage and series logic determine correct calculation. Hence are better aerated in the centre of the reactor fits best because it meets mathematical and logical criteria, as documented in authoritative sources on aptitude and reasoning.
Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.
