Quaternized chitosans bind onto preexisting biofilms and eradicate pre-attached microorganisms.
Quaternized chitosans, N,N,N-trimethylchitosans (TMC) with different degree of quaternization were synthesized by reacting methyl iodide with chitosan. The reaction was confirmed by FT-IR and 1H-NMR characterization. Antimicrobial assay showed that the prepared TMC had potent biocidal effects against planktonic Gram-positive bacteria Staphylococcus epidermidis, Gram-negative bacteria Escherichi...
متن کاملAnti-Biofilm Strategies: How to Eradicate Candida Biofilms?
In nature, microorganisms prefer to reside in structured microbial communities, termed biofilms, rather than as free-floating planktonic cells. Advantageous for the microorganisms, but disadvantageous for human health, is the increased resistance/tolerance of the biofilm cells to antimicrobial treatment. In clinically relevant biofilms, Candida albicans is one of the most frequently isolated mi...
متن کاملBiofilms: survival mechanisms of clinically relevant microorganisms.
Though biofilms were first described by Antonie van Leeuwenhoek, the theory describing the biofilm process was not developed until 1978. We now understand that biofilms are universal, occurring in aquatic and industrial water systems as well as a large number of environments and medical devices relevant for public health. Using tools such as the scanning electron microscope and, more recently, ...
متن کاملMembrane attached biofilms for waste treatment - fundamentals and applications
Membrane Attached Biofilms (MABs) are being used in an increasing variety of bioreactors. Extractive Membrane Bioreactors (EMB) have been developed at Imperial College (1,2) for the aerobic biotreatment of toxic organics which employ MABs for treating Volatile Organic Compounds (V0Cs)-containing wastewaters without incurring air-stripping problems. Investigations of the key factors controlling ...
متن کاملBiofilms: A Survival and Resistance Mechanism of Microorganisms
There is an association between the presence of biofilm-grown microorganisms with delayed wound healing and various diseases such as endocarditis, otitis media, chronic prostatitis, cystic fibrosis, periodontitis, and related infections medical devices and implants responsible for nosocomial infections (Castrillón et al., 2011, Donlan & Costerton, 2002). The latter share common features, althou...
