Three-phase extractive fermentation
Trends in Biotechnology, 1988Abstract Fermentation with simultaneous extraction of a product inside the fermentor is an attractive alternative where substrates and/or products otherwise inhibit processes. Although a large number of systems are being tested, the selection of solvent and the technology and design of the process have nevertheless to be improved.

Extraction chemistry of fermentation product carboxylic acids
Biotechnology and Bioengineering, 1986AbstractWithin the framework of a program aiming to improve the existing extractive recovery technology of fermentation products, the state of the art is critically reviewed. The acids under consideration are propionic, lactic, pyruvic, succinic, fumaric, maleic, malic, itaconic, tartaric, citric, and isocitric, all obtained by the aerobic fermentation

Extraction of Proteins from Fermented Food
The metaproteomic approach allows a deep microbiome characterization in different complex systems. Based on metaproteome data, microbial communities' composition, succession, and functional role in different environmental conditions can be established.The main challenge in metaproteomic studies is protein extraction, and although many protocols have ...Jocelin, Rizo +3 more

Simulated Dynamics and Control of an Extractive Alcoholic Fermentation
Applied Biochemistry and Biotechnology, 2000In this study, we investigated the dynamics of a computer simulation of a continuous alcoholic fermentation process combined with a flash column under vacuum. The alcohol was partially extracted in order to maintain its concentration at about 40 kg/m3 in the fermentor.

Extractive acetonobutylic fermentation by coupling ultrafiltration and distillation
Biotechnology and Bioengineering, 1990AbstractAn extractive acetonobutylic fermentation process is developed by integrating bioproduction, Ultrafiltration, and distillation, providing simultaneous retention of biomass, selective removal of inhibitors from the permeate, as well as separation and purification of acetone–butanol–ethanol solvents.

Strategies for reducing solvent toxicity in extractive fermentations
Biotechnology and Bioengineering, 1991AbstractThe toxicity of an Alamine 336/oleyl‐alcohol extraction system on Lactobacillus delbrueckii was investigated. It was shown that the solvent affected the cells through the water‐soluble portion and the immiscible portion of the solvent. While immobilization significantly protected the cells from the immiscible solvent phase, the water‐soluble ...

A larch based biorefinery: pre-extraction and extract fermentation to lactic acid
Holzforschung, 2011Abstract In a forest based biorefinery, pulp and paper are the main products, while side-streams are utilized for value-added products. One biorefinery concept is to remove hemicelluloses from wood by extraction prior to pulping and converting them into biofuels or chemicals.

Biotechnology and Bioengineering, 1990
AbstractMathematical formulation was made for the performance evaluation of extractive fermentation using multiple solvents. Two types of solvent‐supplying strategies were considered. One is to add multiple solvents simultaneously and the product is removed at one time. Another is to add them one by one consecutively.

Determination of the Fermentability and Extract Content of Industrial Worts by NIR
Journal of the American Society of Brewing Chemists, 1996The aim of this work was to investigate the use of transmission near-infrared spectroscopy (NIR) to determine the fermentability of brewery worts. Samples were collected from two breweries (A and B). The fermentabilities of the worts were determined using the breweries' own yeast strains.
