High‐sensitivity real‐time monitoring of pH and respiration activity unveils metabolic dynamics in shake flask cultures

Biotechnology Progress, Volume 41, Issue 2, March/April 2025.
Abstract Erlenmeyer shake flasks are widely used during the first steps of bioprocess development. Despite their broad application in academia and industry, shake flasks usually lack standardized and user‐friendly online monitoring techniques. In this work, the pH and Respiratory Activity MOnitoring System (pH‐RAMOS) for the non‐invasive online ...

Insights into the Mechanism of a Vanadium Bromoperoxidase from the Marine Macro‐Algae Corallina pilulifera for Biocatalytic Halogenation

ChemCatChem, EarlyView.
A study of crystallographic complexes obtained from vanadium haloperoxidase enzymes can determine key amino acids, leucine, and phenylalanine, that change their structural orientation to allow either chloride or bromide to bind to the enzymes active site, thereby determining halide specificity.

Graphitic Carbon Nitride/Nickel Oxide/Pt Heterojunction Photocatalysts for Hydrogen Production from Ammonia Borane Under White‐Light Irradiation

ChemCatChem, EarlyView.
gCN/NiO Nanocomposites were fabricated and their roles as being both an effective heterojunction and support materials for the in‐situ synthesis of Pt nanoparticles during the hydrolysis of ammonia‐borane were investigated. The optimal gCN/NiO‐3.12%/Pt(IV) heterojunctions (1.31 wt% Pt) provided the highest TOF of 132.9 mol H2mol Pt−1 min−1 in the ...
