Biosensor‐Guided Engineering of a Baeyer‐Villiger Monooxygenase for Aliphatic Ester Production

ChemBioChem, Volume 26, Issue 1, January 2, 2025.
In this work, aliphatic esters are produced by Baeyer‐Villiger monooxygenases (BVMOs) from ketone substrates. Through an artificial enzyme cascade, esters are converted into aldehydes, which are detected by a bacterial luciferase. This set‐up presents the first genetically encoded biosensor system monitoring BVMO activity and greatly accelerated the ...

Volatile Profile of Bee Pollens: Optimization of Sampling Conditions for Aroma Analysis, Identification of Potential Floral Markers, and Establishment of the Flavor Wheel

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
The study describes the aroma composition of bee pollens from Central and Eastern Europe. Each pollen possesses its own specific volatile profile, with a number of aroma‐active ingredients. Terpenoids are of great importance for the overall aroma of bee pollen. The results establish the flavor wheel suitable for the comprehensive sensory description of

Chemical composition of the headspace volatiles of intact cowpea pods and cowpea pods infested by Riptortus dentipes and Nezara viridula pests

Scientific African
Volatile organic compounds are released by plants in defense against herbivory feeding by insect pests. Pod-sucking bugs can cause 30–70 % yield losses in cowpea (Vigna unguiculata) which serves as a major source of rich proteins and vitamins for humans ...
