TLDR
It has been shown that lactate inhibits growth after the log phase and that the maintenance of low lactate concentrations after this point permits higher specific growth rates and higher maximum cell concentrations.Abstract:
Growth and lactic acid production by L. delbrueckii was studied in a dialysis culture system and the inhibitory effect of lactate confirmed by removing lactate from the culture medium by dialysis. It has been shown that lactate inhibits growth after the log phase and that the maintenance of low lactate concentrations after this point permits higher specific growth rates and higher maximum cell concentrations. Acid production is also significantly higher in a dialysis culture system. Finally, a modification of the Luedeking‐Piret model, incorporating the lactate inhibition effect, is proposed.read more

Batch fermentation of whey ultrafiltrate by Lactobacillus helveticus for lactic acid production
TL;DR: Cheese whey ultrafiltrate (WU) was used as the carbon source for the production of lactic acid by batch fermentation with Lactobacillus helveticus strain milano, which will provide an alternative solution to the phage contamination in dairy industries using LactOBacillus bulgaricus.

In situ recovery of fermentation products
TL;DR: In situ recovery of fermentation products can increase the rate of product inhibited fermentations, reduce costs of waste-water treatment and minimize product degradation as mentioned in this paper, and some methods of in situ recovery show more potential than others for the production of chemicals and pharmaceuticals by fermentation.

Lactic acid production by Lactobacillus delbreuckii in a hollow fiber fermenter
TL;DR: Lactic acid was produced by viable Lactobacillus delbreuckii NRRL-B445 in a hollow fiber fermenter and the observed cell yields were appreciably lower than batch cell yields.

TL;DR: Cell-mass production of Serratia marcescens was studied in dialysis systems in which growth was managed in a fermentor remote from, but connected by conduits and pumps with, a nutrient reservoir, believed to be adaptable to any desired scale of size.
