Enzymatic Processes Triggered by PEF for Astaxanthin Extraction From Xanthophyllomyces dendrorhous
Frontiers in Bioengineering and Biotechnology, 2020 The aim of this study was to evaluate the potential of pulsed electric fields (PEF) to improve the extraction of the lipid-soluble astaxanthin from fresh biomass of a wild-type (CECT 11028) and mutant (ATCC 74219) Xanthophyllomyces dendrorhous strain ...

Engineering an Optogenetic pH‐Modulator in Bacteria
Advanced Science, EarlyView.ABSTRACT Cells in many naturally occurring organisms routinely cooperate to control their extracellular pH in a dynamic and reversible manner, but this capability has been underexplored in synthetic biology. Here, we sought to engineer a microbial system that switches between two states —high and low extracellular pH— with minimal human intervention ...

Xenobiotic-hydrolysing esterases from crops and Arabidopses: characterisation of a S-formylglutathione hydrolase [PDF]
, 2003 Esterases represent an ancient family of enzymes, found across all kingdoms, which have diverged and occupied a wide range of functional niches. Because of their biochemical diversity and electrophoretic variability, esterases are widely used as genetic ...

Angewandte Chemie, EarlyView.This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis
Angewandte Chemie, EarlyView.Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...
