Phytochemical Composition, In Vitro Antioxidant, Antibacterial, and Antibiofilm Activities of Thymus vulgaris Essential Oil From Tiaret, Algeria

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Thymus vulgaris essential oil (TvEO), largely composed of thymol, showed strong bactericidal activity with Staphylococcus aureus (S. aureus) being most sensitive. TvEO markedly inhibited MRSA biofilm formation and significantly reduced established biofilms. Molecular docking suggests several TvEO components interact with proteins involved in S.

Dietary Terpenoids in Advancing Biofilm‐Mediated Cancer Prevention: Antibiofilm Cascade, Molecular Crosstalk, and Nano‐Facilitated Functional Delivery

Cell Biochemistry and Function, Volume 44, Issue 8, August 2026.
ABSTRACT The role of microbes in cancer is gaining attention these days, especially in the context of tumor‐associated biofilms and dysbiotic microbiota. Biofilm‐producing microorganisms, such as Fusobacterium nucleatum and Helicobacter pylori, trigger oncogenic inflammation and immune evasion in tumor initiation and progression, and in the development
