The research aims at development of a new fermentor concept. In 1985 one of our collaborators patented a pumped tubular loop reactor: HIPERLOOP. This reactor proved to be able to overcome the main limiting factor of aerobic industrial fermentors: oxygen transfer due to improper mixing. Especially for viscous media where oxygen transfer is very low, HIPERLOOP is expected to increase the volumetric productivity and thereby reduce energy use and cost price considerably.
Disadvantage at that time was the impossibility to recycle cells from the reactor in a cost effective way. Our research aims to integrate the two technologies and will take advantage of new developments in cell-recycle systems to complete the concept. The technology will be used to develop three types of processes: Lysine, Citric acid and Biopolymer fermentation. For these processes a significant cost reduction (20-50%) will be realised.
