The Potential of Non-Ionic Surfactants for Extraction of Lactic Acid from Aqueous Solution

open access: yesApplied Sciences, 2020
Lactic acid, an important commodity chemical for various applications, is mainly produced through fermentation. In this study, the potential of non-ionic surfactants (an alcohol ethoxylate (AE) and two alcohol alkoxylates (AAs)) as solvents for the ...

Water-soluble phenolic compounds produced from extractive ammonia pretreatment exerted binary inhibitory effects on yeast fermentation using synthetic hydrolysate. [PDF]

open access: yesPLoS ONE, 2018
Biochemical conversion of lignocellulosic biomass to liquid fuels requires pretreatment and enzymatic hydrolysis of the biomass to produce fermentable sugars. Degradation products produced during thermochemical pretreatment, however, inhibit the microbes

Increased Water-Soluble Yellow Monascus Pigment Productivity via Dual Mutagenesis and Submerged Repeated-Batch Fermentation of Monascus purpureus

open access: yesFrontiers in Microbiology, 2022
Monascus pigments (MPs) have been used in the food industry for more than 2,000 years and are known for their safety, bold coloring, and physiological activity. MPs are mainly yellow (YMPs), orange (OMPs), and red (RMPs).

Effects of extractive fermentation on butyric acid production by Clostridium acetobutylicum [PDF]

open access: yes, 1990
The addition of an oleyl alcohol extractant to a batch fermentation of glucose by Clostridium acetobutylicum resulted in a concentration profile that was distinctly different from the non-extractive control fermentation. The concentration of butyric acid

Perstraction of Intracellular Pigments through Submerged Fermentation of Talaromyces spp. in a Surfactant Rich Media: A Novel Approach for Enhanced Pigment Recovery

open access: yesJournal of Fungi, 2017
A high percentage of the pigments produced by Talaromyces spp. remains inside the cell, which could lead to a high product concentration inhibition. To overcome this issue an extractive fermentation process, perstraction, was suggested, which involves ...
