Assuming a yield of 0.132 g•g -1 , the overall stoichiometric reaction on a molar basis for microbial oil production from oilcane hydrolysate becomes: The maximum volume of each aerated bioreactor was 500 m 3 , a "world's largest" class that exists in small numbers. The number of vessels is computed based on the influent flow rate, reaction time, and cleaning time (3 h).
