Transforming micropores to mesopores by heat cycling KOH activated petcoke for improved kinetics of adsorption of naphthenic acids

open access: yesHeliyon, 2023
Formation of activated carbon from petroleum coke by KOH, results in high specific surface area materials that are predominantly microporous. This initial microporosity means that the adsorption kinetics of target species are not as rapid as they could ...

Production of medium-chain carboxylic acids by Megasphaera sp MH with supplemental electron acceptors [PDF]

open access: yes, 2016
Background: C5-C8 medium-chain carboxylic acids are valuable chemicals as the precursors of various chemicals and transport fuels. However, only a few strict anaerobes have been discovered to produce them and their production is limited to low ...

Determination of the Fatty Acids in Beer by SPME.

open access: yesKvasný průmysl, 2005
An escalated content of fatty acids during fermentation can influence the quality of final beer. So it is necessary to use the suitable analytical method for the determination of their concentrations in beer or hopped wort.

An Improved Validated Method for the Determination of Short-Chain Fatty Acids in Human Fecal Samples by Gas Chromatography with Flame Ionization Detection (GC-FID)

open access: yesMetabolites, 2023
Short-chain fatty acids (SCFAs) are metabolites produced by the gut microbiota through the fermentation of non-digestible carbohydrates. Recent studies suggest that the gut microbiota composition, diet and metabolic status play an important role in the ...

Biohydrogen production from food waste: Influence of the inoculum-to-substrate ratio [PDF]

open access: yes, 2018
In this study, the influence of the inoculum-to-substrate ratio (ISR) on dark fermentative hydrogen production from food waste (FW) was evaluated. ISR values ranging from 0.05 to 0.25 g VSinoculum/g VSsubstrate were investigated by performing batch tests

Production of Medium Chain Fatty Acids From Ensiled Potato Peels; Effect of Inoculum Type and Kinetic Study

open access: yesNigerian Journal of Technological Development, 2023
Medium chain fatty acids (MCFAs) are fatty acids containing 6 to 12 carbon atoms with a wide range of industrial application. They can be produced by the fermentation of waste biomass through a process called chain elongation (CE).
