Introduction

The kinetics of batch propionic acid fermentation by Propionibacterium acidipropioniei was studied. This was used to develop the mathematical model of the process. The model was extrapolated to develop fed batch nutrient feeding strategies which were experimentally implemented to achieve highly productive propronic acid fermentation. The insitu cell retention device significantly improved the propronic acid productivity further with out clogging or pressure drop problem in a 7 litre fermenter.
