The present study was preformed to evaluate the effect of dip treatments by thyme (Thymus vulgaris) extract (0.5%) and rosemary (Rosmarinus officinalis) (1.5%) on quality shelf life Nile tilapia (Orechromis niloticus) fillets during refrigerated storage at 2 ± 1 °C. control (untreated) treated groups were examined periodically day zero every 3 days (0, 3, 6, 9, 12, 15, 18, ....) refrigeration until apparent decomposition each group, with sensory, physicochemical microbiological methods....
Immunoassays are nowadays a crucial tool for diagnostics and drug development. However, they often involve time‐consuming procedures need at least two antibodies in charge of the capture detection processes, respectively. This study reports nanocomposite based on graphene oxide‐coated nanopaper (GONAP) facilitating an advantageous immunosensing platform using single antibody without washing steps. The hydrophilic, porous, photoluminescence‐quenching character GONAP allows adsorption...
Marrubium vulgare is a valuable source of natural bioactive molecules with high preventive and therapeutic effectiveness. Therefore, this study aimed to the chemical polymorphism populations M. in Tunisia by quantitative markers estimation divergence between populations. Phytochemical analyses eight Tunisian prospected different bioclimatic stages, revealed 42 compounds essential oils representing 96.08% 100% total oil. Hydrocarbon sesquiterpenes were main fraction all studied β-bisabolene...
Turned ON by a pathogen: A highly sensitive pathogen-detection system has been designed and evaluated for the sensing of E. coli bacteria in diverse matrices. It employs antibody–quantum dot (Ab-QD) probes exploits extraordinary two-dimensional structure fluorescence-quenching capabilities graphene oxide.
Due to the growing world population and increasing environmental stress, improving production, nutritional quality, pharmaceutical applications of plants have become an urgent need. Therefore, current research was designed investigate impact seed priming using plant-growth-promoting bacteria (PGPB) along with selenium nanoparticles (SeNPs) treatment on chemical biological properties three Brassica oleracea cultivars [Southern star (VA1), Prominence (VA2), Monotop (VA3)]. With this aim, one...
Abstract It is well known that the quality and quantity of bioactive metabolites in plants microorganisms are affected by environmental factors. We applied heat stress as a promising approach to stimulate production antioxidants four heat-tolerant bacterial strains (HT1 HT4) isolated from Aushazia Lake, Qassim Region, Saudi Arabia. The phylogenetic analysis 16S rRNA sequences indicated HT1, HT3 HT4 belong genus Bacillus . While HT2 closely related Pseudooceanicola marinus with 96.78%...

The demand for healthy foods with high functional value has progressively increased. Carbon nanoparticles (CNPs) have a promising application in agriculture including the enhancement of plant growth. However, there are few studies on interactive effects CNPs and mild salinity radish seed sprouting. To this end, effect priming 80mM biomass, anthocyanin, proline polyamine metabolism, antioxidant defense system under growth condition (25 mM NaCl). results indicated that nanopriming along stress...
We have produced thin film samples of cubic ZnS by the chemical bath method. These were synthesized using zinc chloride, thiourea, sodium citrate and ammonia solutions at varied deposition time from 24h to 96h. X-ray diffraction (XRD), transmittance photoluminescence (PL) analyses provided physical characteristics films with crystal plane orientations (2 0 0) 2 2), lattice parameters 5.648 Å an atomic distance d=1.412 Å. The grain size calculed are 16.53 nm 17.12 nm. PL revealed deep defects...
This study aims at exploiting salinity stress as an innovative, simple, and cheap method to enhance the production of antioxidant metabolites enzymes from bacteria for potential application functional additives foods pharmaceuticals. We investigated physiological biochemical responses four bacterial isolates, which exhibited high tolerance 20% NaCl (wt/vol), out 27 strains isolated Aushazia Lake, Qassim region, Saudi Arabia. The phylogenetic analysis 16S rRNA genes these isolates indicated...
Compared to seeds and mature plants, sprouts are well characterized based on their nutritive values biological properties. Moreover, laser light application is known be a promising approach improving plant growth, photosynthesis, nutraceutical values. However, no studies have investigated the phytochemicals activity of lemongrass (Cymbopogon proximus (Hochst. ex A.Rich.) Chiov.) or further improvement quality by applying treatment. We carried out preliminary experiment for optimization...
The present study was designed in order to estimate the prevalence of Salmonella spp. broiler carcasses and human stools Beni-Suef province (Egypt). Also, serological identification testing antimicrobial resistance/susceptibility isolates have been done. obtained results revealed that meat, skin, pooled giblets (liver, gizzard, heart) 76, 80, 64%, respectively, while case percentage positive samples represented 4%. predominant serotype Infantis (56.36%) followed by Kentucky (25.45%), then...
Brassica sprouts are known as a good source of antimicrobial bioactive compounds such phenolics and glucosinolates (GLs). We aim at understanding how He–Ne laser light treatment (632 nm, 5 mW) improves sprout growth physiology stimulates the accumulation metabolites in three spp., i.e., mustard, cauliflower, turnip. Moreover, these changes consequently promote their biological activities. Laser improved growth, photosynthesis, respiration, which induced primary secondary metabolites. boosted...
Edible sprouts are rich in flavonoids and other polyphenols, as well proteins, minerals, vitamins. Increasing sprout consumption necessitates improving their quality, palatability, bioactivity. The purpose of this study was to test how KNO3 priming affects the sprouting process species on three Medicago (Medicago indicus, interexta, polymorpha) nutritional values. Targeted were primed with KNO3, levels different primary secondary metabolites determined. induced biomass accumulation species,...
