Screening Fermentation and Extract Generation
2021This chapter describes the process of fermenting actinomycetes in flask and the generation of extracts from these broths. A medium for secondary metabolite production and a general procedure for flask fermentation are specified. Directions are given to reproduce aeration when using different flasks.

Ethanol production by extractive fermentation
Biotechnology and Bioengineering, 1982AbstractThe ideal method to produce a terminal metabolite inhibitor of cell growth and production is to remove and recover it from the fermenting broth as it formed. Extractive fermentation is achieved in the case of ethanol production by coupling both fermentation and liquid‐liquid extraction, The solvent of extraction is 1‐dodecanol (or a mixture 1 ...

Multimembrane Bioreactor For Extractive Fermentation
Biotechnology Progress, 1986AbstractA multimembrane reactor is described. Four layers (gas, cells, nutrient, and solvent) are separated by membranes. This structure prevents solvent emulsification in the fermentation broth. The system was tested for ethyl alcohol production from glucose using yeast. Tributyl phosphate (TBP) was chosen as the extractant.

AN investigation is being carried out on a sample of malt extract which, after standing for some months, was found to have fermented. As the extract contains about 50 per cent of sugars, mostly maltose, any organism capable of ferment must be highly osmophilic.

Antioxidant Activity of Fermented Soybean Extract
Journal of Agricultural and Food Chemistry, 2004Free radicals are considered to be important causative factors in the development of cancer and cardiovascular diseases. This relationship has led to interest in evaluating the antioxidant capacities of many dietary supplements. Fermented soybean extract is produced by symbiotic fermentation of organic soybean with 20 types of Lactobacillus and yeast ...

Extractive fermentation of aroma with supercritical CO2
Biotechnology and Bioengineering, 1999This work deals with the feasibility of achieving an extractive fermentation of 2-phenylethyl alcohol, the rose aroma, coupling fermentation with Kluyveromyces marxianus and supercritical carbon dioxide (SCCO2) extraction. The extractive process is, in this case, of special interest due to the strong yeast inhibition by 2-phenylethyl alcohol.

In situ extractive fermentation of acetone and butanol
Biotechnology and Bioengineering, 1988AbstractThe productivity of the acetone–butanol fermentation was increased by continuously removing acetone and butanol from the fermentation broth during fed‐batch culture. Whole broth containing viable cells of Clostridium acetobutylicum was cycled to a Karr reciprocating plate extraction column in which acetone and butanol were extracted into oleyl ...

Selection of Solvents for Extractive Fermentations
Berichte der Bunsengesellschaft für physikalische Chemie, 1989AbstractProduct 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, 1993The 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, 2016Acetoin 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
