Abstract Many research papers are currently being written about various methodologies for the green synthesis of ZnO nanoparticles. In this study, nanoparticles were prepared by method using baker’s yeast ( Saccharomyces cerevisiae ). The characterization produced involved utilization XRD, FTIR, SEM, and TEM. investigation assessment antimicrobial potential photocatalytic degradation efficacy synthesized materials through Eriochrome Black T (EBT). results indicate that exhibit a spherical morphology, exhibiting diameters ranging from 13.0 to 20.0nm, with an average particle size 15.0nm. against S. aureus ) gram-positive E. coli gram-negative bacteria was tested conduction zone inhibition (ZOI) minimum inhibitory concentration (MIC) tests. This focused on study photocatalytic-degradation EBT in presence ultraviolet light. experiments impact factors, such as pH levels, initial concentration, nanocatalyst dosage, observed efficiency. vitro ZOI MIC assay, it (NPs) exhibited greater , measuring 23.1 mm 0.625 μg/ml. contrast, effectiveness ZnO-NPs comparatively lower, indicated 17.0 1.250μg/ml. greatest elimination, which achieved 83.0% equilibrium, found employing 20.0mg NPs at 3.0, according activity results. synthetic powerful antibacterial agents effective may be used treatment wastewater.

Abstract Background and objectives Microbial cells capability to tolerate the effect of various antimicrobial classes represent a major worldwide health concern. The flexible multi-components nanocomposites have enhanced physicochemical characters with several improved properties. Thus, different biological activities biosynthesized starch/silver-selenium nanocomposite (St/Ag-Se NC) were assessed. Methodology St/Ag-Se NC was using Cladosporium cladosporioides CBS 174.62 ( C. ) strain. shape average particle size investigated scanning electron microscope (SEM) high-resolution transmission (HR-TEM), respectively. On other hand, on two cancer cell lines red blood (RBCs) evaluated its hydrogen peroxide (H 2 O scavenging Moreover, effects microbial species in both planktonic biofilm growth forms examined. Results successfully oval spherical mean diameter 67.87 nm as confirmed by HR-TEM analysis. showed promising anticancer activity toward human colorectal carcinoma (HCT-116) breast (MCF-7) where IC 50 21.37 19.98 µg/ml, Similarly, little RBCs observed low concentration. As well, highest H (42.84%) recorded at concentration mg/ml. Additionally, Staphylococcus epidermidis S.

Glycine Betaine Mitigates Heavy Metal Toxicity in Beta vulgaris (L.): An Antioxidant-Driven Approach

Agronomy, Год журнала: 2024, Номер 14(4), С. 797 - 797

Опубликована: Апрель 11, 2024

Plants are often exposed to non-ideal conditions during their growth. The toxicity of heavy metals as abiotic stressors is a significant concern due harmful effects on plants. Glycine betaine (GB) potent compatible solute that helps plants resist stresses and plays crucial role in alleviating them. This study aimed determine the effective glycine (0.5 1 mM) foliar treatment sugar beet cope with cadmium (50 mg/kg soil) lead (100 soil). application (Pb) (Cd) cultivation soil noticeably suppressed morphological growth attributes, such chlorophylls, carotenoids, sugars, proteins. At same time, aforementioned levels significantly increased non-enzymatic antioxidants (phenolics proline) enzymatic (peroxidase, superoxide dismutase, polyphenol oxidase, catalase) root shoot tissues In contrast, use at 0.5 mM alleviated adverse impacts by promoting attributes. Furthermore, GB was more increasing contents phenolics approximately 16% 29%, about 25% 10%, peroxidase activity 82% 116%, dismutase 56% 47%, oxidase 9% 36%, catalase 19% 25%, cadmium- lead-stressed plants, respectively. Additionally, it reduced proline tissues. Overall, has efficacy counteract enhancing metabolic indices well antioxidant activities.

Abstract Most vegetable crops are severely affected by the uptake of heavy metals from soil. Heavy in bodies generate reactive oxygen species (ROS) that unbalance antioxidant defense system. This study was initiated to determine physiological and biochemical characteristics spinach plants grown on soil contaminated with responding Bacillus cereus aerius were isolated metals. metal contamination led a significant reduction seed germination, seedling biomass, protein, total nitrogen content soils compared control soils. In contrast, increase metallothioneins enzymes observed. Plants inoculated B. significantly reduced oxidative stress induced improving germination (%), growth, nitrogen, protein content. The activities seeds bacterial strains. addition, with, showed greater stomata opening than metals, whose almost closed. These results suggested both strains enhanced plant growth reducing caused
