Characterization of Anti-Biofilm Peptide Activity: A Biophysical Approach [PDF]

Biophysical Journal, 2017
The increasing number of multidrug resistant bacteria to available antibiotics is a growing problem worldwide. One major strategy for resistance and an important reason for failure of therapy in the clinic is biofilm formation. To cope with unfavorable surroundings many bacteria live as biofilms, sessile micro-colonies adherent to surfaces that secrete

Transfer of AgNPs’ Anti-Biofilm Activity into the Nontoxic Polymer Matrix

Polymers, 2023
A biological method was successfully applied to synthesize spherical silver nanoparticles (AgNPs) while using the extract of lavender (Ex-L) (lat. Lavandula angustifolia) as the reducing and stabilizing agent. The produced nanoparticles were spherical with an average size of 20 nm.

Biochemical Properties and Anti-Biofilm Activity of Chitosan-Immobilized Papain [PDF]

Marine Drugs, 2021
Chitosan, the product of chitin deacetylation, is an excellent candidate for enzyme immobilization purposes. Here we demonstrate that papain, an endolytic cysteine protease (EC: 3.4.22.2) from Carica papaya latex immobilized on the matrixes of medium molecular (200 kDa) and high molecular (350 kDa) weight chitosans exhibits anti-biofilm activity and ...

Lactobacillus plantarum Lipoteichoic Acids Possess Strain-Specific Regulatory Effects on the Biofilm Formation of Dental Pathogenic Bacteria

Frontiers in Microbiology, 2021
Bacterial biofilm residing in the oral cavity is closely related to the initiation and persistence of various dental diseases. Previously, we reported the anti-biofilm activity of Lactobacillus plantarum lipoteichoic acid (Lp.LTA) on a representative ...

Anti-biofilm studies of synthetic imidazolium salts on dental biofilm in vitro

Journal of Oral Microbiology, 2022
Objective Biofilm formation under cariogenic conditions contributes to dental caries development, in which Streptococcus mutans (S. mutans) is regarded as the major cariogenic bacteria. Here, we synthesized a series of imidazolium salts. Their properties

A Bacteriophage Mediated Gold Nanoparticles Synthesis and Their Anti-biofilm Activity [PDF]

Indian Journal of Microbiology, 2017
In the present study, gold nanoparticles (AuNPs) synthesis was carried out by using a rare bacteriophage which is morphologically similar to 7-11 phages of the C3 morphotype of tailed phage belonging to Podoviridae family as green route. Effect of various physiological parameters like pH, temperature and concentration of gold chloride salt on AuNPs ...
