A Novel Metallo‐β‐Lactamase AMM‐1 From Alteromonas mangrovi Reveals a Cryptic Environmental Reservoir of Carbapenem Resistance

open access: yesMicrobial Biotechnology, Volume 18, Issue 7, July 2025.
We identified and characterised AMM‐1, a novel metallo‐β‐lactamase from Alteromonas mangrovi in the Yangtze River Estuary. AMM‐1 clusters with clinically relevant MBLs. Structural modelling reveals a conserved di‐zinc active site essential for β‐lactam hydrolysis; AMM‐1 shows distinct active‐site flexibility compared with representative MBLs ...

Exploring the Role of Microglial Cells in the Gut–Brain Axis Communication: A Systematic Review

open access: yesJournal of Neurochemistry, Volume 169, Issue 7, July 2025.
Gut microbiota composition influences brain health through the gut–brain axis by modulating microglial activation states. A balanced microbiota promotes the production of beneficial metabolites like short‐chain fatty acids (SCFAs), which maintain gut barrier integrity and support anti‐inflammatory surveillance microglia, contributing to neuroprotection

Guava root exudate‐driven rhizosphere microorganisms changes transmitted to foliar‐feeding insects influence their feeding behaviour

open access: yesPlant Biotechnology Journal, Volume 23, Issue 7, Page 2963-2977, July 2025.
Summary The growth of different grafted guava was different as affected by grafting on different rootstock varieties, which also influenced the damage degree of Spodoptera litura larvae. The co‐regulation of the pest gut by rhizosphere microorganisms and root exudates may contribute to this differential damage. In this study, the microorganisms of soil,

Safety and efficacy of a feed additive consisting of endo‐1,4‐beta‐xylanase EC 3.2.1.8 produced by Bacillus subtilis LMG S‐15136 (Belfeed B MP/ML) for gestating sows (Puratos NV)

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Belfeed B MP/ML as a feed additive for gestating sows when used at 10 IU/kg feed.
