Complexation between Hg(II) and biofilm extracellular polymeric substances: An application of fluorescence spectroscopy

, 2010
The three-dimensional excitation emission matrix (EEM) fluorescence spectroscopy was employed to investigate the interaction of extracellular polymeric substances (EPS) from natural biofilm with Hg(II).

Antimicrobial photodynamic therapy in Candida spp. biofilms: In vitro and in vivo protocols

Photochemistry and Photobiology, EarlyView.
This review addresses the critical challenges in translating in vitro antimicrobial photodynamic therapy protocols to in vivo models, with a particular focus on the hurdles of standardization. The vast diversity in photosensitizers and light parameters across different target cells and models requires a rigorous optimization process.

233 nm far‐UV‐C radiation for biofilm inactivation

Photochemistry and Photobiology, EarlyView.
Based on tests to assess biofilm formation potential (crystal violet staining, color of colonies grown on Congo red agar and calcofluor agar), three bacterial genera/species/strains (Staphylococcus (S.) epidermidis, S. aureus, Pseudomonas (P.) aeruginosa) were selected for analysis of their biofilm matrix composition.

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

CrustCheck: a conceptual framework for interpreting biocrust trait–function relationships in drylands

Restoration Ecology, EarlyView.
Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Native biocrust microbes modulate salinity‐driven recruitment filters in coastal wetlands

Restoration Ecology, EarlyView.
Abstract Introduction Mediterranean coastal wetlands are biodiversity hotspots increasingly threatened by climate change, particularly by salinization, which strongly constrains plant recruitment during early life stages. Native soil microbiota may provide nature‐based solutions (NbS) to enhance plant establishment under saline conditions.

Extracellular polymeric substances (EPS) in sewage sludge management: A call for methodological standardization

Journal of Environmental Management
Extracellular polymeric substances (EPS) are crucial in sewage sludge management, influencing key processes such as sedimentation, dewatering, and drying. Despite their importance, the lack of standardized methods for EPS extraction and analysis has led to inconsistent research findings, hindering a thorough understanding of EPS's role in sludge ...
