Anti-microbial efficacy of L-glutaminase (EC 3.5.1.2) against multidrug-resistant Pseudomonas aeruginosa infection.

The aims of this study were isolation-purification and characterization of L-glutaminase from L. gasseri BRLHM clinical isolates and investigation of its efficiency as an antimicrobial agent against multidrug-resistant P. aeruginosa.

Establishing novel roles of bifidocin LHA, antibacterial, antibiofilm and immunomodulator against Pseudomonas aeruginosa corneal infection model.

Bifidocin LHA, a novel bacteriocin, was extracted from bee honey B. adolescentis and purified. Bifidocin LHA was characterized as a protein in nature, without lipid or carbohydrate moieties, the molecular weight was 16,000 Da protein, heat-stable and active at a wide range of pH values, bactericidal effect, detergent, and solvents did not affect bifidocin activity and can be classified as type II bacteriocin.
