Factors affecting the fermentative lactic acid production from renewable resources1
TL;DR: Parameters affecting the fermentative lactic acid (LA) production are summarized and discussed: microorganism, carbon- and nitrogen-source, fermentation mode, pH, and temperature.
Journal ArticleDOI
Recent advances in lactic acid production by microbial fermentation processes
TL;DR: This review will discuss lactic acid producers with relation to their fermentation characteristics and metabolism, and introduces inexpensive fermentative substrates, such as dairy products, food and agro-industrial wastes, glycerol, and algal biomass alternatives to costly pure sugars and food crops.
Journal ArticleDOI
Cheese whey management: a review.
TL;DR: The paper describes the main reactors used, the influence of the main operating variables, the microorganisms or reagents employed and the characterizations of the final effluent principally in terms of chemical oxygen demand and the comparison between the different treatment alternatives is postulated.
Journal ArticleDOI
Bioutilisation of whey for lactic acid production
TL;DR: A review of the various biotechnological techniques that have used whey for the production of lactic acid can be found in this paper, where the authors focus on the various technologies that have been applied to whey fermentation processes.

Fed-batch fermentation for n-butanol production from cassava bagasse hydrolysate in a fibrous bed bioreactor with continuous gas stripping
TL;DR: Stable production of n-butanol from glucose in the CBH was maintained in the fed-batch fermentation over 263 h with an average sugar consumption rate of 1.28 g/L h and butanol productivity of 0.32±0.01 g/g glucose for butanol.

Extractive fermentation for lactic acid production
V. M. Yabannavar,D. I. C. Wang +1 more
TL;DR: In this article, the use of an efficient extractive fermentation system was demonstrated using Alamine 336 in oleyl alcohol at acidic pH using cell immobilization procedure, which resulted in a higher productivity compared to that of a control fermentation.
Journal ArticleDOI
Continuous lactic acid fermentation with concentrated product recovery by ultrafiltration and electrodialysis
TL;DR: To increase the, productivity of the lactic acid fermentation and to reduce the amounts of effluents, the bioreactor was coupled with an ultrafiltration module and an electrodialysis unit.

The effect of yeast extract supplementation on the production of lactic acid from whey permeate by Lactobacillus helveticus
A. Aeschlimann,U. von Stockar +1 more
TL;DR: In this article, the effect of yeast extract (YE) on the homolactic fermentation of whey permeate by Lactobacillus helveticus was investigated and it was shown that supplementing with YE had a significant effet on lactic acid concentration, volumetric productivity, and substrate conversion.

Continuous propionate production from whey permeate using a novel fibrous bed bioreactor.
TL;DR: Compared to conventional batch fermentors, the new bioreactor offers many advantages for industrial fermentation, including a more than 10‐fold increase in productivity, acceptance of low‐nutrient feedstocks such as whey permeate, and resistance to contamination.
