Selection of Solvents for Extractive Fermentations

Berichte der Bunsengesellschaft für physikalische Chemie, 1989
AbstractProduct yield in fermentation processes is often limited by product inhibition or degradation. This may be avoided by extracting the product from the broth during the fermentation. Solvents to be used in these extractive fermentations must be selective for the product and nontoxic for the microorganisms.

Effects of Aspergillus oryzae fermentation extract on in vitro equine cecal fermentation

Journal of Animal Science, 1993
The objective of this study was to examine the effects of Aspergillus oryzae fermentation extract on the in vitro equine cecal fermentation of soluble starch, amino acids/peptides, coastal bermudagrass hay, and alfalfa hay. Cecal contents were obtained from a cecally fistulated Quarter Horse gelding fed coastal bermudagrass and grain (70:30) either ...

Sugaring-out extraction of acetoin from fermentation broth by coupling with fermentation

Bioprocess and Biosystems Engineering, 2016
Acetoin is a natural flavor and an important bio-based chemical which could be separated from fermentation broth by solvent extraction, salting-out extraction or recovered in the form of derivatives. In this work, a novel method named as sugaring-out extraction coupled with fermentation was tried in the acetoin production by Bacillus subtilis DL01. The

Simultaneous saccharification and extractive fermentation of cellulosic substrates

Biotechnology and Bioengineering, 1996
Alcohol fermentation has traditionally been carried out in aqueous environments because of the ready solubility of reactant (sugar) and product (ethanol). However, extraction of the product ethanol into a nonmiscible phase can result in kinetic benefits due to reduced inhibition of the fermentation reactions. In this study, we report the development of

Secondary Metabolites by Extractive Fermentation

1990
Product yield infermentation processes is often limited by product inhibition or degradation. This may be avoided by extracting the product from the broth during fermentation. Solvents to be used in these extractive fermentations must be selective for the product and non-toxic for the microorganism.

Performance improvement of lactic acid fermentation by multistage extractive fermentation

Journal of Fermentation and Bioengineering, 1996
For the efficient fermentation of lactic acid, an integrated fermentation system in which a cell recycle process with cross-flow filtration and extraction were combined, was developed. Forty percent Alamine 336 was used as an extractant (dissolved in a solvent of oleyl alcohol) for selectively extracting lactic acid from cell-free broth.

Three-phase extractive fermentation

Trends in Biotechnology, 1988
Abstract 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, 1986
AbstractWithin 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 ...

Simulated Dynamics and Control of an Extractive Alcoholic Fermentation

Applied Biochemistry and Biotechnology, 2000
In 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.
