Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Putrescine-mediated biofilm development in activated sludge under low-temperatures: A novel regulatory mechanism

Desalination and Water Treatment
Low temperatures impair microbial activity in both biofilms and activated sludge, limiting their efficacy in wastewater treatment. While these systems share functional similarities, their microbial dynamics under stress differ significantly.

Biofilm‐Mediated Persistence of Salmonella in Poultry Processing: A Comprehensive Review of Isolate Heterogeneity, Stress Adaptation, and Antimicrobial Resistance [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT Salmonella enterica remains a major foodborne pathogen in poultry‐processing environments, where its persistence is largely attributed to biofilm formation on food‐contact and non‐food‐contact surfaces. Despite extensive research on Salmonella control, persistent contamination continues to challenge food safety due to the complex interplay ...

Contribution of Extracellular Polymeric Substances (EPS) to the Sludge Aggregation

, 2016
The contribution of extracellular polymeric substances (EPS), including loosely bound EPS (LB-EPS) and tightly bound EPS (TB-EPS), to the aggregation of both aerobic and anaerobic sludge is explored using the extended DLVO theory. It is observed that the

Architecture and Evolution of Prokaryotic Multicellularity: Common Patterns and Diversity

Molecular Microbiology, EarlyView.
Prokaryotes form diverse multicellular structures, like biofilms, filaments, and aggregates, comprising hallmark traits such as adhesion, communication, differentiation, and programmed cell death. This review explores how these forms develop, function, and evolve in response to environmental cues.
