Extractive microbial fermentation in cloud point system
Enzyme and Microbial Technology, 2010Extractive microbial fermentation of organic compounds in liquid-liquid two-phase systems is a potential strategy to overcome the limitations of microbial fermentation in an aqueous solution, such as low substrate solubility, substrate/product inhibition and product further degradation.

Investigation of extractive citric acid fermentation using response-surface methodology
Process Biochemistry, 2002 Extractive citric acid fermentation with Aspergillus niger microoganism was investigated in the presence of corn oil and Hostarex A327 in oleyl alcohol. In the extractive fermentation, production and separation phases are achieved simultaneously.

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.

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.

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 ...

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.

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 ...

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 ...
