AbstractThe antiradical activity of phytol was evaluated by electron paramagnetic resonance towards hydroxyl radical (√OH), superoxide anion (), methoxy (√CH2OH), carbon-dioxide as well nitric-oxide (√NO) and 2,2-diphenyl-1-picrylhydrazyl (√DPPH) radical. It reduced the production all tested radicals showing more promising against , √CH2OH √DPPH (56%, 50% 48%, respectively) in comparison with √NO, √OH (38%, 23% 15%, respectively). The antimicrobial microdilution method eight bacterial fungal...
Anti-quorum sensing activity of the diterpene phytol was evaluated in vitro for first time. This compound (at three sub-MIC concentrations – 0.5, 0.25 and 0.125 MIC, respectively) reduced formation Pseudomonas aeruginosa PAO1 biofilm range 74.00–84.33% exhibiting higher than both positive controls used, streptomycin ampicillin. Phytol (0.5 MIC) also effectively P. twitching flagella motility. Indeed, bacteria treated were incapable producing a zone had almost round, smooth regular colony...
This work was focused on in vitro evaluation of anti-biofilm and anti-quorum sensing effects four selected flavonoid compounds /(+)-catechin, caffeic acid, quercetin morin/ using the strain Pseudomonas aeruginosa PAO1. At a concentration 0.5 MIC only compound found to potently reduce both P. biofilm formation (95%) its twitching motility. The chemical scaffold quercetin, common dietary polyphenol, may actually inspire development novel more effective medicinal agents targeting aeruginosa,...
This work covers the chemical composition and antimicrobial activities of essential oils isolated from Satureja thymbra Thymbra spicata analyzed using GC/MS. The main components S. oil were thymol (33.8 %), ?-terpinene (30.8 %) p-cymene (11.8 %). in T. carvacrol (74.5 (11.2 their components, carvacrol, assayed by applying microdilution method for antibacterial antifungal activity against food poisoning, plant, animal human pathogenic microorganisms. showed highest activity.
The edible mushroom Agaricus blazei Murill is known to induce protective immunomodulatory action against a variety of infectious diseases. In the present study we report potential anti-quorum sensing properties A. hot water extract. Quorum (QS) plays an important role in virulence, biofilm formation and survival many pathogenic bacteria, including Gram negative Pseudomonas aeruginosa, considered as novel promising target for anti-infectious agents. this study, effect sub-MICs extract on QS...

Abstract Objectives The chemical composition, antimicrobial and synergistic effect, cytotoxic activity of Citrus limon (lemon), Piper nigrum (green pepper) Melaleuca alternifoila (tea tree) essential oils (EOs) were investigated. Methods Chemical analyses tested by GC-FID GC-MS spectroscopy. assay was conducted using microdilution method against several oral bacteria Candida spp. originating from the humans with disorders. evaluated checkerboard method. cytotoxicity evaluation EOs assessed...
The anti-quorum sensing activities towards the bacterium Pseudomonas aeruginosa PA01 (pyocyanin production, biofilm formation and twitching flagella motility) of two crude extracts (methanol acetone) freshwater sponge Ochridaspongia rotunda (Arndt, 1937) were evaluated in vitro for first time. Both demonstrated P. pyocyanin inhibitory activity, reducing its production 49.90% 42.44%, respectively. In addition, they both showed higher anti-biofilm activity (48.29% 53.99%, respectively) than...
A decision-making approach based on Data Envelopment Analysis (DEA) for determining the efficient container handling processes (considering number of employed Automated Guided Vehicles (AGVs)) at a port terminal (PCT) is presented in this paper. Containers are unloaded from ship by quay cranes and transported to storage area AGVs. We defined performance measures proposed analysed effects when changing The values were collected and/or calculated simulation. Container process, with fixed...
Essential oils are well known as strong antimicrobial agents of plant origin. In spite this, the synergism essential isolated from different species is poorly investigated. The following study examines Origanum vulgare L. and Thymus vulgaris L against pathogenic bacteria, Staphylococcus aureus Salmonella typhimurium. First, antibacterial effect was tested, minimal inhibitory concentrations (MIC) both were determined using microdilution method. To test whether act synergistically, every...
Anti-biofilm activity of three anthocyanidins (pelargonidin, cyanidin and delphinidin) was evaluated for the first time at in vitro conditions. All compounds reduced formation Pseudomonas aeruginosa PAO1 biofilm low sub-MIC (0.125 MIC) with delphinidin (c 56.25 μg/mL) being most active (43%). In comparison, ampicillin 93.75 streptomycin 21.25 (used as positive controls) were considerably less effective same (8 12%, respectively). Furthermore, 0.5 MIC 225 this anthocyanidin molecule partly...
This work extends in vitro screening of antimicrobial activity the sesquiterpene hydroquinone avarol, a main secondary metabolite Mediterranean sponge species Dysidea avara. The was part evaluated by microdilution method against selected bacterial and fungal strains. Additionally, included evaluation anti-quorum sensing (anti-QS) effects. At different extent avarol proven to be active all microorganisms tested (MIC 0.002-0.008 mg/mL MBC 0.004-0.016 mg/mL; MIC 0.004-0.015 MFC 0.008-0.030...
