Continuous cultivation of lactic acid bacteria

There have been numerous studies on the conversion of sugars, including glucose, lactose and sucrose, to lactic acid and valuable secondary metabolites with lactic acid bacteria in different types of processes to achieve higher productivity. The fermentation by conventional methods that use cell suspension in batch processes has several limitations, such as low productivity, product inhibition and also the variation from batch to batch. Cell immobilization techniques have become more important and popular because it gives many advantages compared to cell suspension culture such as maintenance of stable and active biocatalysts, accelerated reaction rates, high volumetric productivity, improved process control, reduced susceptibility of cells to contamination, improved production efficiency and no possibility of washout.

The aim of this project is to optimize the performance of long-term cultures of lactic acid bacteria in a fixed-bed reactor system.
