Abstract Using plant extracts in the green synthesis of nanoparticles has become an environmentally acceptable approach. In our study, copper oxide (CuO NPs) were synthesized using ethanolic Azadirachta indica and Simmondsia chinensis . CuO NP formation was confirmed by change color UV‒visible spectroscopy NPs peaked at a wavelength 344 nm). TEM images semispherical shape NPs, with particle sizes ranging from 30.9 to 10.7 nm. The antibacterial activity these evaluated agar diffusion method...
Exposure to ultraviolet (UV) radiation is one of the major factors that causes skin aging, erythema, sunburns, and cancer. This study aimed select probiotic bacterial isolates able produce high yield hyaluronic acid (HA) be employed for photoprotection other possible biological applications. The selected K11 St3 were highest yields HA 4.8 4.4 mg/ml, respectively. Both identified as Enterococcus durans strain Lactiplantibacillus plantarum using 16S rRNA gene sequencing. antioxidant activity...
Crop nutrition depends on zinc for enzymatic, oxidative, and metabolic processes. In the current study 20 different bacteria were isolated from five soil samples collected fields in Egypt. Bacterial isolates screened their ability to solubilize insoluble oxide carbonate. The of selected tolerate soluble was determined using concentrations (ZnSO4). Three bacterial with efficiency solubilizing carbonate while tolerating high levels zinc. Molecular identification by 16S rRNA sequencing chosen...

The growth and spread of pathogenic bacteria resistant to commercial antibiotics is one the biggest issues facing world today. aim this study was investigate rates antibiotic resistance that cause infections as well prevalence characteristics prescriptions among hospitalized patients. A total 330 clinical samples including sputum, blood, pus, wound, urine were collected from female male patients aged 9 82 years. Two hundred isolated identified subjected susceptibility testing. Gram-negative...
Six bacterial strains were tested for the production of dextransucrase. The highest dextransucrase activities produced by local strain Leuconostoc paramesenteroides after 24 h in static culture conditions. Dextransucrase was induced using sucrose (10 g%) as a carbon source and corn steep liquor (3.5 ml%) nitrogen source. Fe 2+ favoured enzyme production. Cells L. immobilized three supports, calcium alginate, agar κ-carrageenan. Calcium alginate beads able to produce four runs with 100%...
Biological nitrogen fixation is highly regulated at the transcriptional level by sophisticated regulatory networks that respond to multiple environmental signals. Glutamine synthetase (GS) occupies a central position in cellular metabolism and offer cell, potential point for regulation of biosynthetic function. The aim this work enhance activity GS Paenibacillus polymyxa through altering constituents growth medium, thereby increasing capability. Two bacterial strains were identified as P....
