Identification and Biocontrol of Mindarus japonicus Takahashi, a New Pest of Abies koreana E.H.Wilson Using Bacillus velezensis CE 100

Entomological Research, Volume 56, Issue 7, July 2026.
ABSTRACT Subalpine conifers such as Abies koreana E.H.Wilson (Korean fir) play a significant ecological role but are increasingly endangered due to the effects of climate change, including the high prevalence of insect pests. This study identified for the first time, a notorious aphid pest on newly developed needles and twigs of A.

Direct Competitive Kinetic Isotope Effect Measurement Using Quantitative Whole Molecule Matrix‐Assisted Laser Desorption Ionization Time‐of‐Flight Mass Spectrometry

ChemBioChem, Volume 27, Issue 12, 26 June 2026.
Kinetic Isotope effect (KIE) measurements are a powerful tool to interrogate enzyme mechanisms and transition state structures. In this study, we develop a simple quantitative MALDI‐TOF mass spectrometry approach to measure competitive heavy atom KIEs.

Redox Properties of Catalytically Generated Iminium Ions From α,β‐Unsaturated Aldehydes and Chiral Secondary Amines

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...

Metal‐Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...

The significant contribution of biomass burning to methanol-soluble nitrogenous organics and its evolution during the highly-humid haze event in urban Wuhan

npj Climate and Atmospheric Science
Fine particle (PM2.5) controls in China have achieved great success these years, but heavy haze pollution still occurs occasionally. The sources and evolution of the complex organic mixtures remain poorly resolved.

Semi‐Rational Engineering of Formate Dehydrogenase Reveals Loop Dynamics as a Key Determinant of Thermostability

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Semi‐rational engineering yields a thermostable Bacillus simplex formate dehydrogenase variant (Q125F) with a 25‐fold longer half‐life at 60°C and strong resistance to chemo‐inactivation. Molecular dynamics reveal enhanced π–π interactions stabilizing a flexible loop and enabling efficient NADH regeneration for robust biocatalytic detoxification ...
