Sequential Pressurized Liquid Extraction of Food Matrices: Fractionation, Selectivity, and Scale‐Up

ChemFoodChem, EarlyView.
Sequential pressurized liquid extraction separates food‐processing side streams into chemically distinct fractions by changing solvent polarity and operating conditions across stages. Lipophilic and phenolic compounds are recovered selectively, while co‐extraction is reduced.

Dilemma in Carotenoids Versus Polyhydroxyalkanoates (PHAs) Synthesis Using Haloarchaea as Cell Factories

Chemistry – A European Journal, EarlyView.
Production of PHAs by haloarchaea: the production of carotenoids and PHAs is concomitant, and consequently, various metabolic pathways compete for the carbon source. This results in a loss of PHA production efficiency. Efficient control of carbon source utilization (favoring certain metabolic pathways at the expense of others) is the key to the ...
