Article Abstract
biofilm is a significant virulence factor in infection. This study aimed to investigate antibacterial and antibiofilm activities of extract against . The MIC and MBC values of the extract against the isolates were 0.5-1.0 mg/mL. At 2 × MIC, the cells showed cell shrinkage and abnormalities. At 1/2 × MIC, the extract displayed 40-71% inhibition of biofilm formation. At 8 × MIC, the extract reduced the viability of mature biofilms by 60-86%. Hydroxychavicol and eugenol, the main compounds in the extract, showed binding activity to CdpA, an enzyme implicated in biofilms as observed by studies. Hydroxychavicol exhibited the highest affinity for CdpA, with a distance of 2.27 Å. Molecular dynamics simulations revealed that hydroxychavicol forms a stable complex with cyclic di-GMP phosphodiesterase, maintaining protein structural integrity with minimal conformational changes. The results suggested that may have medicinal benefits by inhibiting biofilm-related infections.

Introduction: This study evaluates two innovative protective treatments for wooden cultural heritage objects vulnerable to biodeterioration. The first involves polyacrylic resin solutions embedded with silver nanoparticles (AgNPs), while the second uses the siloxane-based coupling agent 3-mercaptopropyltrimethoxysilane (3-MPTMS) to enhance AgNP adhesion to wood surfaces.
Methods: Antimicrobial, anti-biofilm, and anti-metabolic activities were assessed using both qualitative and quantitative assays against biodeteriogenic strains (, and ).

Although citrus essential oils, including lemongrass essential oil, have antibacterial, anti-biofilm, and antioxidant properties, their biological instability and poor water solubility render them unsuitable for industrial usage. Thus, this study aimed to prepare both lemongrass essential oil emulsion (LEO-E) and lemongrass essential oil nanoemulsion (LEO-NE), and evaluate their different bioactivities. Characterization by gas chromatography-mass spectroscopy (GC-MS) and evaluation of antimicrobial, antibiofilm, antioxidant, and anticancer activities were carried out.

Multidrug-resistant (MDR-KP) is a major pathogen responsible for hospital-acquired infections, associated with high morbidity and mortality. Biofilm formation plays a key role in the pathogenicity of MDR-KP and contributes significantly to its antibiotic resistance, substantially impairing the effectiveness of antimicrobial therapies. To enhance the efficacy of existing antibiotics, this study investigates a biofilm-targeting synergistic strategy inspired by the structural similarity between sputum and biofilm matrices.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.
