Soil Microbiota and Rhizosphere Dynamics: Ecological Mechanisms Driving Crop Stress Adaptation in Climate‐Smart Agriculture

Food and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT Climate change‐mediated abiotic stresses limit crop performance, and plant responses are increasingly recognized as emergent properties of the coupling between soil, plants, and microbiomes rather than inherent plant characteristics. This review synthesizes mechanistic evidence from 2020 to 2025 on how rhizosphere microbiota contribute to crop

The Antiproliferative Effect of Cyclodipeptides from Pseudomonas aeruginosa PAO1 on HeLa Cells Involves Inhibition of Phosphorylation of Akt and S6k Kinases

Molecules, 2017
Pseudomonas aeruginosa PAO1, a potential pathogen of plants and animals, produces the cyclodipeptides cyclo(l-Pro-l-Tyr), cyclo(l-Pro-l-Phe), and cyclo(l-Pro-l-Val) (PAO1-CDPs), whose effects have been implicated in inhibition of human tumor cell line ...

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, Volume 29, Issue 4, Page 537-547, July 2026.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

Polymer Engineering &Science, Volume 66, Issue 7, Page 5191-5199, July 2026.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.
