Occurrence and expression of novel methyl-coenzyme M reductase gene (mcrA) variants in hot spring sediments

Scientific Reports, 2017
Recent discoveries have shown that the marker gene for anaerobic methane cycling (mcrA) is more widespread in the Archaea than previously thought.

Understanding Biofilm-Phage Interactions in Cystic Fibrosis Patients Using Mathematical Frameworks [PDF]

arXiv, 2023
When planktonic bacteria adhere together to a surface, they begin to form biofilms, or communities of bacteria. Biofilm formation in a host can be extremely problematic if left untreated, especially since antibiotics can be ineffective in treating the bacteria.

Theory of Ion and Electron Transport Coupled with Biochemical Conversions in an Electroactive Biofilm [PDF]

Phys. Rev. Applied 12 (2019) 014018, 2019
Bioelectrochemical systems are electrochemical cells that rely on conductive biofilms covering an electrode. We consider the example of a microbial fuel cell, and we derive a dynamic model of ion transport, biochemical reactions and electron transport inside such a biofilm.

Staphylococcal Biofilms [PDF]

Microbiology Spectrum, 2008
ABSTRACTStaphylococci, with the leading speciesStaphylococcus aureusandStaphylococcus epidermidis, are the most frequent causes of infections on indwelling medical devices. The biofilm phenotype that those bacteria adopt during device-associated infection facilitates increased resistance to antibiotics and host immune defenses. This review presents and

Identification of small molecules that interfere with c-di-GMP signaling and induce dispersal of Pseudomonas aeruginosa biofilms

npj Biofilms and Microbiomes, 2021
Microbial biofilms are involved in a number of infections that cannot be cured, as microbes in biofilms resist host immune defenses and antibiotic therapies.

Development of an in vitro periodontal biofilm model for assessing antimicrobial and host modulatory effects of bioactive molecules [PDF]

, 2014
Background: Inflammation within the oral cavity occurs due to dysregulation between microbial biofilms and the host response. Understanding how different oral hygiene products influence inflammatory properties is important for the development of new ...

A novel approach for harnessing biofilm communities in moving bed biofilm reactors for industrial wastewater treatment

AIMS Bioengineering, 2015
Moving bed biofilm reactors (MBBRs) are an effective biotechnology for treating industrial wastewater. Biomass retention on moving bed biofilm reactor (MBBR) carriers (biofilm support materials), allows for the ease-of-operation and high treatment ...

A Novel Approach to Produce Metal–Metal Composites by Leveraging Immiscibility: Laser Powder Bed Fusion of Nanosilver‐Dispersed Titanium

Advanced Engineering Materials, EarlyView.
Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...
