Kinetic modeling of lactic acid production, co-substrate consumptions and growth in Lactiplantibacillus plantarum 60-1

Lactiplantibacillus plantarum is a Gram-positive bacterium that belongs to the lactic acid bacteria (LAB) group commonly used in food industry. To use this microorganism, high biomass concentration necessary, and models need be established for predicting improving its behavior along fermentation. However, current L. are applicable only one substrate. The growth of newly isolated strain 60-1 co-substrate (glucose lactose) production batch process, were modeled work. Biomass was well described bydouble Monod kinetics. Substrate consumptions using two balance equations. Lactic with Luedeking–Piret equation. No product inhibition observed. Both glucose lactose metabolized concomitant way. This first report (as we know it) model includes dynamics dual limitation substrate glucoseand multiplicative effects on
