  • The concentration of the chemicals tested as anti-biofilm agents was chosen based on cytotoxicity assays: the highest non-cytotoxic chemical concentration was used for biofilm inhibition assays, with dendrimer concentration 10-fold higher than polyamino-phenolic ligands. (frontiersin.org)
  • opportunistic
  • NCs provide a portal of entry for a wide diversity of opportunistic pathogens to colonize the catheter lumen, forming a biofilm and increasing the potential for CAI, highlighting the importance of catheter maintenance practices to reduce microbial contamination. (asm.org)
  • polymeric
  • Biofilm is usually defined as a microbial community enveloped in a self-produced polymeric matrix. (clinicaltrials.gov)
  • Enmech Biofilm Carriers is a new kind of suspension carriers, it modified polymeric materials with the promoted additions of bio-enzyme, it improves the enzymatic catalysis, so it possess excellences of larger specific surface, being easy to multiply biofilm, unease to fall.

  • form
  • The quantification of biofilm relays currently on a number of different approaches and techniques, often leading to different evaluations of the ability to form biofilms of the studied microbial strains. (mdpi.com)
  • The minerals provide food for the biofilm of microorganisms that form the stromatolites. (upi.com)
  • This work is focussed on a range of biofilms in the mouth and in the head and neck region as a whole, including biofilms that form on artificial speech valves, in the paranasal sinuses (causing chronic rhinosinusitis) and in the middle ear (causing glue ear). (ncl.ac.uk)
  • Drinking water quality may be degraded in water distribution systems-microorganisms form biofilms within distribution systems that allow them to flourish. (wiley.com)
  • Bacterial ability to form biofilms was verified using a crystal violet colorimetric assay and testing cell viability by real-time quantitative PCR and Plate Count assay. (frontiersin.org)
  • Poor quality source water and poorly treated reused wastewater may result in poor quality drinking water that has a higher potential to form biofilms. (scielo.org.za)
  • surface
  • Depending on the environmental conditions, these secreted components of the colony biofilm can also promote the flagellum-independent surface spreading of B. subtilis , called sliding. (mdpi.com)
  • When establishing a biofilm, cells of the Gram-positive soil dwelling microbe Bacillus subtilis secrete extracellular polysaccharides (EPS), a matrix protein component (TasA), and a hydrophobin protein that assembles on the surface (BslA) [ 3 , 4 , 5 , 6 ]. (mdpi.com)
