Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, Volume 13, Issue 8, 9 February 2026.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Advancements and Challenges in the Production of Biosurfactants: A Path Toward Sustainable Surfactant Alternatives

ChemBioEng Reviews, Volume 13, Issue 1, February 2026.
Microorganisms generate versatile biosurfactants with a wide range of uses. Although cost issues still exist, industrial interest is growing because to the advantages of sustainability, which are enhanced by genetic engineering; life cycle evaluation is crucial for scalable, environmentally responsible production.

Asymmetric One‐Pot Total Synthesis of Tenuipesone A/B Through a Tunable Multienzyme Cascade

ChemistryEurope, Volume 4, Issue 2, February 2026.
This study presents a tunable, enzyme‐based, one‐pot synthesis of the fungal spirolactones tenuipesone A/B from furfural. The cascade achieves up to 72% overall yield at >99% enantiopurity and enables the absolute stereochemical reassignment of the natural metabolites. The method eliminates intermediate purification, valorizes biorefinery side streams,
