With the rise of antibiotic resistance, there is an increasing interest in discovering novel antimicrobial agents. Antibiotics could be replaced with metal-based nanoparticles that have long-lasting antibacterial properties. This study aimed to synthesize gold (AuNPs) and test their effectiveness against a variety human pathogens. The AuNPs were characterized using UV, FT-IR, XRD, TEM EDX. By well diffusion microdilution techniques, impact synthesized was tested B. subtilis, S. aureus, E....
Lead (Pb) is one of the most dreadful non-essential elements whose toxicity has been well reported worldwide due to its interference with major plant functions and overall yield. Bioremediation techniques comprising application beneficial microorganisms have gained attention in recent times owing their ecofriendly nature. Addition organic matter soil stimulate microbial activities. Compost improves structure binds toxic contaminants larger surface area presence functional groups....
Water pollution is a major global challenge due to the fast expansion of industrial activities and increasing human population. Certain heavy metals can be exceedingly hazardous contribute significantly water contamination. In this study, iron oxide nanoparticles (IONPs) were synthesized using cyanobacteria extract remove (Cd Pb) from wastewater. To characterize IONPs, several analytical techniques employed such as Ultraviolet-visible spectroscopy revealed an SPR (surface plasmon resonance)...
Capsicum is a common spice used in food flavouring. However, they are prone to mycotoxin contamination. Mycotoxins natural toxins produced by filamentous fungi and can pose serious risks human health. Fungal contamination was assessed 130 randomly collected samples following ISO 21527–2:2008 standards. Results revealed that 84.6% of the exceeded acceptable fungal count limit (102 CFU/g) according Gulf Cooperation Council (GCC) standards (GSO1016:2015). The predominant isolates were...
Essential oils have been known to possess useful biological activities and are widely used in aromatherapy owing their peculiar aroma. The present study compared the essential oil composition isolated from Chinese Saudi ginger cultivars determined antimicrobial activity. volatile compounds were extracted by a hydrodistillation method was analysed gas chromatography coupled with mass spectrometry (GC–MS). antibacterial activity of tested against pathogenic Gram positive negative bacterial...
Bacteriocins are proteins or peptides synthesized by bacteria that show inhibitory killing activities against various bacteria. mainly considered for effective alternatives to different commercial antibiotics, preservatives in the food and pharmaceutical industries.To screen analyze novel bacteriocin-producing from fermented shidal antibacterial activity pathogens their molecular interactions studied through computationally.In this study, a strain Lactobacillus plantarum LA21 was isolated...
Early blight (EB), caused by Alternaria solani, is a serious problem in tomato production. Plant growth-promoting rhizobacteria promote plant growth and inhibit disease. The present study explored the bio-efficacy of synergistic effect rhizobacterial isolates ginger powder extract (GPE) against EB disease, singly combination. Six fungal from symptomatic plants were identified as A. solani on basis morphological features i.e., horizontal septation (6.96 to 7.93 µm), vertical (1.50 2.22...
Staphylococcus aureus is a significant opportunistic pathogen in humans, dairy cattle, and camels. The presence of antibiotic-resistant heat-resistant bacteria camel milk has become potential public health issue. phenotypic molecular characterization methicillin-resistant staphylococcal strains recovered from pasteurized distributed retail markets Saudi Arabia was assessed. A total 100 samples were collected between March May 2017. Out the 20 S. isolates that milk, 10 found to be resistant...
The consumption of foods contaminated with various foodborne organisms such as, viruses, fungi and bacteria are recognized as the important sources illness in animals humans. Multidrug resistant increased morbidity, mortality rates, severe economic loss associated prolong hospitalization. development natural novel antibacterial agent is much needed there an increasing concern on multidrug bacteria. This study aimed to synthesize silver nanoparticles using aqeous Pisum sativum L. (pea) pod...
The application of green synthesis for silver nanoparticles in nanomedicine has experienced significant growth. Strobilanthes glutinosus, a plant primarily located the Himalayas, remains largely unexplored. Considering biomedical value S. phytochemicals from this were used biosynthesis nanoparticles. Silver synthesized aqueous extract root and leaves glutinosus. characterized using UV–Vis spectrophotometry, Fourier-transform infrared spectroscopy, transmission electron microscopy, X-ray...
Nanotechnology is one of the most advance and multidisciplinary fields. Recent advances in nanoscience nanotechnology radically changed way we diagnose, treat, prevent various diseases all aspects human life. The use plants their extracts valuable methods towards rapid single-step protocol preparation for nanoparticles, keeping intact "the green principles" over conventional ones proving dominance medicinal importance. A facile eco-friendly technique synthesizing silver nanoparticles has...
Chromium (Cr) is classified as an ecological toxin, and irrigation of soil with raw industrial effluents causes its concentration in plants to reach fatal levels. Due reduced metal mobility caused by organic amendment availability food for microbial activity, use Cr-tolerant rhizobacteria conjunction compost has proven be useful supporting development survival plants. We checked the simultaneous effects on spinach (Spinacia oleracea) growth, physiology, biochemistry uptake Cr. Plants were...
Staphylococcus aureus and Escherichia coli contribute to global health challenges by forming biofilms, a key virulence element implicated in the pathogenesis of several infections. The study examined efficacy various generations cephalosporins against biofilms developed pathogenic S. E. coli. development both bacteria was assessed using petri-plate microplate methods. Biofilm hydrolysis inhibition were tested first fourth cephalosporins, effects analyzed crystal violet staining phase...
Abstract In many developing countries, there are certain health problems faced by the public, one among them is Malaria. This tropical disease mainly caused Plasmodium falciparum . It categorized as a disaster to public health, which increases both mortality and morbidity. Numerous drugs in practice control this their vectors. Eco-friendly tools required battle against vector of significant disease. Nanotechnology plays major role fighting malaria. The present paper synthesized Zinc oxide...
Inoculation with Bacillus subtilis is a promising approach to increase plant yield and nutrient acquisition. In this context, study aimed estimate the B. concentration that increases yield, gas exchange, nutrition of lettuce plants in hydroponic system. The research was carried out greenhouse Ilha Solteira, Brazil. A randomized block design five replications adopted. treatments consisted concentrations solution [0 mL “non-inoculated”, 7.8 × 10 3 , 15.6 31.2 62.4 colony forming units (CFU) −1...
In the present study, a total of 50 raw camel meat samples were analyzed for presence Listeria monocytogenes. The isolates characterized via morphological and culture analyses; identification was confirmed by polymerase chain reaction (PCR) sequencing listeriolysin O gene. API system used further chemical verification strains. L. monocytogenes identified in eight samples, which highest incidence (16%) contamination, followed seeligeri 3(6%), innocua welshimeri 2 (2% each), grayi 1 (1%)....
