Three strains of Pseudomonas fluorescens with different motility rates and adsorption rate coefficients were injected into porous-medium reactors packed with l-mm-diameter glass spheres. Cell breakthrough, time to peak concentration, tailing, and cell recovery were measured at three interstitial pore velocities (higher than, lower than, and much lower than the maximal bacterial motility rate). ...

Keratinase producing bacterial strains were isolated from the chicken feather dumping site. Keratinase producing bacterial strains were identified by physical, biochemical characteristics, fatty acid methyl ester (FAME) and 16S rDNA sequences. Medium optimization of the selected keratinase producing bacterial strain (Bacillus thuringiensis TS2) was checked with various parameters such as incuba...

The beneficial effects of Juniperus communis L. extracts have been known for a long time. Therefore scientific knowledge the chemical profile leading to this bioactivity is required. aim paper highlight influence geographical origin and harvest time on compositional elements hydroalcoholic J. pseudo-fruits, but also their antibacterial properties. samples were collected from three mountainous a...

We report the synthesis of medicinal plant, Vernonia amygdalina Del. mediated green copper oxide nanoparticles (VeA-CuO NPs). The presence two absorbance maxima, λmax 1 and 2 at 436 nm 452 nm, respectively confirms a mixture biomolecules surface amalgamated CuO NPs with different morphological features. FT-IR spectra plant leaf extract VeA-CuO confirmed efficient role as capping stabilising age...

Nickel biosorption ability was evaluated in two bacterial strains: Acinetobacter baumannii UCR-2971 and Pseudomonas aeruginosa UCR-2957, resulting in greatest adsorption at pH 4.5 and a residence time of 100 minutes. Biosorption isotherms showed that the process follows the Langmuir model. The maximum adsorption rates (Nmax) were 8.8 and 5.7 mg·g for A. baumannii and P. aeruginosa, respectively...

An ongoing outbreak of conjunctivitis in free-ranging house finches (Carpodacus mexicanus) began in 1994 in the eastern United States. Bacterial organisms identified as Mycoplasma gallisepticum (MG) were isolated from lesions of infected birds. MG was also isolated from a blue jay (Cyanocitta cristata) that contracted conjunctivitis after being housed in a cage previously occupied by house finc...

Background: Development of antibiotic resistance or multidrug (MDR) is one the major causes treatment failure bacterial infections and has rapidly evolved into a threat to global health care. Bacterial efflux pumps play significant role in development resistance. This study evaluates prevalence pump- mediated drug clinical isolates P. aeruginosa.Methods: Clinical (n=100) aeruginosa were collect...

The objective of this study was to develop a bioremediation strategy for cadmium (Cd) and carbendazim co-contaminated soil using a hyperaccumulator plant (Sedum alfredii) combined with carbendazim-degrading bacterial strains (Bacillus subtilis, Paracoccus sp., Flavobacterium and Pseudomonas sp.). A pot experiment was conducted under greenhouse conditions for 180 days with S. alfredii and/or car...
