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

Integration of a pure moving bed biofilm reactor process into a large micro-polluted water treatment plant

Water Science and Technology, 2022
The pure-MBBR process was applied to remove ammonia in a full-scale micro-polluted-water treatment plant with a daily treatment capacity of 260 × 104 m3/d, Guangdong, China.

Quorum Sensing in Halorubrum saccharovorum Facilitates Cross-Domain Signaling between Archaea and Bacteria

Microorganisms, 2023
Quorum Sensing (QS) is a well-studied intercellular communication mechanism in bacteria, regulating collective behaviors such as biofilm formation, virulence, and antibiotic resistance.

Privatization of Biofilm Matrix in Structurally Heterogeneous Biofilms

mSystems, 2019
Biofilms are communities of bacteria protected by a self-produced extracellular matrix. The detrimental effects of nonproducing individuals on biofilm development raise questions about the dynamics between community members, especially when isogenic nonproducers exist within wild-type populations.

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.

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.

Enhanced coagulation of covalent composite coagulant with potassium permanganate oxidation for algae laden water treatment: Algae and extracellular organic matter removal

Chemical Engineering Journal Advances, 2023
The enhanced coagulation performance for algae and extracellular organic matter (EOM) removal by using novel Al/Fe-based covalently bonded composite coagulants (CAFM) coupled with potassium permanganate oxidation was evaluated in the current study.

The sociobiology of biofilms [PDF]

FEMS Microbiology Reviews, 2009
Biofilms are densely packed communities of microbial cells that grow on surfaces and surround themselves with secreted polymers. Many bacterial species form biofilms, and their study has revealed them to be complex and diverse. The structural and physiological complexity of biofilms has led to the idea that they are coordinated and cooperative groups ...

Poloxamer 338 Affects Cell Adhesion and Biofilm Formation in Escherichia coli: Potential Applications in the Management of Catheter-Associated Urinary Tract Infections

Pathogens, 2020
Poloxamers are nontoxic, amphiphilic copolymers used in different formulations. Due to its surfactant properties, Poloxamer 338 (P388) is herein proposed as a strategy to avoid biofilm formation often causing recalcitrant catheter-associated urinary ...

To Build a Biofilm [PDF]

Journal of Bacteriology, 2003
Development is not restricted to so-called higher organisms. Developmental processes in bacteria include differentiation of a single cell, such as the swarmer-to-stalk transition by Caulobacter crescentus and spore formation by Bacillus subtilis .
