Factors influencing 4-fluorobenzoate degradation in biofilm cultures of Pseudomonas knackmussii B13.
Membrane aerated biofilm reactors (MABRs) have potential in wastewater treatment as they permit simultaneous COD minimisation, nitrification and denitrification. Here we report on the application of the MABR to the removal of fluorinated xenobiotics from wastewater, employing a Pseudomonas knackmussii monoculture to degrade the model compound 4-fluorobenzoate. Growth of biofilm in the MABR usin...
Abstract The study was aimed at analyzing chemical composition, and biological antibiofilm activity of Salvia officinalis L. essential oil (EO) with MALDI-TOF MS Biotyper. main compounds S. EO were a-thujone 24.6%, camphor 20.6%, 1,8-cineole 12.1%, a-humulene 5.8%. Free radical scavenging medium high. highest antimicrobial observed against Bacillus subtilis . Changes in the biofilm structure co...
Polyurethane polymer plays an important role in health care, and it is widely used in medical devices and instruments. However, the low biocompatibility and biofilm formation on the surface can be regarded as a challenging issue. Engineering the wetting capability of the surface is an effective way to increase the biodegradability of polymer surfaces with sufficient bulk properties. In this stu...
Background & Objectives: Dental caries is the most important disease caused by some bacteria specially Streptococcus Mutans from Viridans family. The aim of this study is to evaluate the inhibitory effect of Chlorella vulgaris extract on growth, proliferation, and biofilm formation of Streptococcus mutans. Materials & Methods: Microalgae Chlorella vulgaris was extracted via maceration using ch...
BACKGROUND Biofilm formation is a primary cause of considerable bacterial destruction. OBJECTIVES In an effort to combat these industrial and medical bacterial biofilm problems, our study aims to determine the antimicrobial effect of Euphorbia hebecarpa. MATERIALS AND METHODS The inhibition efficiency of alcoholic extracts on the planktonic form of six pathogenic bacteria was evaluated usin...

Here we report on 21 the application of the MABR to the removal of fluorinated xenobiotics from wastewater, 22 employing a Pseudomonas knackmussii monoculture to degrade the model compound 423 fluorobenzoate. Growth of biofilm in...
BACKGROUND The frequent occurrences of antibiotic-resistant biofilm forming pathogens have become global issue since various measures that had been taken to curb the situation led to failure. Euphorbia hirta, is a well-known ethnomedicinal plant of Malaysia with diverse biological activities. This plant has been used widely in traditional medicine for the treatment of gastrointestinal, bronchia...
Bap (biofilm-associated protein) is a 254-kDa staphylococcal surface protein implicated in formation of biofilms by staphylococci isolated from chronic mastitis infections. The presence of potential EF-hand motifs in the amino acid sequence of Bap prompted us to investigate the effect of calcium on the multicellular behavior of Bap-expressing staphylococci. We found that addition of millimolar ...
results the minimum inhibitory concentrations (mics) of ginger extract for evaluated strains were 40, 40, 20, 20, 20, 20, 10, and 5 mg/ml for pseudomonas aeruginosa, escherichia coli, staphylococcus aureus, klebsiella pneumoniae, bacillus cereus, acinetobacter baumannii, c. albicans, and c. krusei, respectively. ginger extract successfully inhibited biofilm formation by a. baumannii, b. cereus,...
