special reactor design for investigations of mixing time effects in a scaled-down industrial L-lysine fed-batch fermentation process

A specially designed model reactor based on a 42-L laboratory fermentor was equipped with six stirrers (Rushton turbines) and five cylindrical disks. In this model reactor, the mixing time, theta90, turned out to be 13 times longer compared with the 42-L standard laboratory fermentor fitted with two...
