Hence, the development of a model to study the cells released from biofilms based on the widely used fed-batch systems may provide significant insights into the pathophysiology of biofilm-related infections.
However, the biomass productivity was further improved to 0.104 g L−1day−1 by using fed-batch mode and increasing the CO2-air ratio up to 1%%.
The stability of the additional steady state (steady state 4) was confirmed by dynamic simulations using fed-batch strategy prior to initiation of continuous operation.
Using fed-batch fermentation through repeatedly adding non-sterilized substrate directly, YZJ074 could produce 312.05 g/L xylitol which is the highest yield reported to date.
In other studies, the productivity in extractive fermentation using fed-batch operation, without immobilization, a glucose concentration of 300 g/l and oleyl alcohol as extractant, increased 70% with respect to conventional batch process (Roffler et al. 1988).
Another approach will be the combination of the strategy presented here using fed-batch processing, with in situ product removal by foam fractionation (Beuker et al. 2016) and thus avoiding the necessity of chemical antifoaming agents.
When using fed-batch systems, the replacement of spent medium and the inherent washing steps are fundamental to replenish nutrients and to remove, respectively, non- or biofilm loosely adherent cells.
The results demonstrated that photo-hydrogen production using fed-batch operation based on ORP feedback control is a favorable choice of sustainable and feasible strategy to improve phototrophic hydrogen production efficiency.
Using fed-batch fermentation with an optimized medium, the engineered pathway could produce 4 g/L β-carotene, which was stored in lipid droplets within engineered Y. lipolytica cells.
Using fed-batch fermentation, more than 100 g/L R-BDO (1100 mM) was synthesized from a mixture of glucose and galactose, two major carbohydrate components in red algae.
A first generation genetically modified strain of Corynebacterium glutamicum has been assessed for its potential to synthesise and accumulate the vitamin pantothenic acid in the medium using fed-batch cultivation technology, with biomass concentration controlled by isoleucine limitation.
