The biofilm formation is a dynamic process of bacterial growth,and the extracellular components can encase these microorganisms,making them more resistant to antibiotics and host immune attack.The formation of antibiotic-resistant bacterial biofilms will be a major challenge for the treatment and control of clinical infections. is a common clinical pathogen.Hypervirulent and carbapenem-resistant can cause serious infectious diseases,and the formation of its biofilm will aggravate this situation.In-depth research on the formation of biofilm and its regulatory mechanism can shed light on clinical anti-infection treatment and control.This article mainly reviews the latest research progress in the effects of fimbriae,polysaccharides,quorum sensing systems,and efflux pumps on the formation of biofilm and their regulatory mechanisms.

Dispersal plays a crucial role in the development and ecology of biofilms. While extensive studies focused on elucidating the molecular mechanisms governing this process, few have characterized the associated temporal changes in composition and structure. Here, we employed solid-state nuclear magnetic resonance (NMR) techniques to achieve time-resolved characterization of Bacillus subtilis biofilms over a 5-day period.

Global demand for food has driven expansion and intensification of livestock production, particularly in developing nations where antibiotic use is often routine. Waste from poultry production, including manure, is commonly utilized as fertilizers in agroecosystems, risking environmental contamination with potentially zoonotic bacteria and antimicrobial resistance genes (ARGs). Here, 33 bacterial isolates were recovered from broiler (n=17) and layer (n=16) chicken manure by aerobic culture using Luria Bertani agar.

The fabrications of circularly polarized luminescent (CPL) material are mainly based on the chemical and physical strategies. Controlled biosynthesis of CPL-active materials is beset with difficulties due to the lack of bioactive luminescent precursors and bio-reactors. Enlighted by microbe-assisted asymmetric biosynthesis, herein, we show the in situ bacterial fermentation of Komagataeibacter sucrofermentants to fabricate a series of bacterial cellulosic biofilms with CPL of green, orange, red, and near-infrared colors.

The current study was designed to evaluate the antibacterial, antibiofilm, and biofilm inhibitory potential of six medicinal plants, including Trachyspermum ammi, Trigonella foenum-graecum, Nigella sativa, Thymus vulgaris, Terminalia arjuna, and Ipomoea carneaid against catheter-associated bacteria (CAB). Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.

Extracellular polymeric substances (EPS) are well-acknowledged to accelerate microalgal biofilm formation, yet specific role of stratified EPS is unknown. Bacterial biofilm stratified EPS could enrich phosphorus, whether microalgal biofilm stratified EPS could also realize phosphorus or nitrogen enrichment remains unclarified. This study investigated microalgae dominant biofilm growth characteristics and nutrients removal via inoculating microalgae and stratified bacterial EPS at various microalgae:bacteria ratios.
