Soil pollution due to heavy metal (HM) contamination has emerged as a global issue worldwide owing their adverse impacts on plant growth. Bioremediation approaches employing living organisms for HM alleviation have gained considerable attention among scientific communities. Biological agents such growth-promoting rhizobacteria (PGPR) offer sustainable way restore soil health, and combination with different organic amendments press mud (PM) can serve potential approach immobilizing HMs in soil. We performed pot experiment evaluate the role of individual combined application PGPR strain 'FQ6' (identified Pseudomonas fluorescens) phytoremediation (Pb, Ni Cd) growth promotion aloe vera. Combined FQ6 PM yielded more significant outcomes terms all yield attributes leaf length (123%), height (57%), number leaves (115%), fresh dry weights gel (246 280%), contents (96%), root (164%), diameter (220%), no. tips (138%) area (315%), compared control. also led improvement antioxidant activities i.e., CAT (129%), SOD (48%), APX (17%) POD (83%) Contrastingly, mobility tested was reduced under PM, there existed difference between concentrations body. concluded that joint HM-tolerant could be an ideal option alleviate induced vera by them soil, subsequently, improving

Effects of Supplemental Potassium on the Growth, Photosynthetic Characteristics, and Ion Content of Zoysia matrella under Salt Stress

Horticulturae, Год журнала: 2023, Номер 10(1), С. 31 - 31

Potassium is crucial in plant metabolism processes, and sufficient potassium can improve tolerance to abiotic stress. We studied the effects of different KCl concentration treatments (0, 1, 5, 20 mM) on biomass, photosynthetic characteristics, ion content Zoysia matrella under salt stress (NaCl 300 mM). The results showed that dry weight, stomatal conductance, transpiration rate, photosynthesis K+ plants, K+/Na+ ratio leaves NaCl were significantly lower than those no conditions. addition K promote an increase weight rate plants. In addition, stress, mM reduce accumulation Na+ plants secretion leaves, thus improving matrella.

The Characterization and Study of Antibacterial, Free Radical Scavenging, and Anticancer Potential of Livistona chinensis-Mediated Silver Nanoparticles

Molecules, Год журнала: 2023, Номер 28(23), С. 7773 - 7773

Опубликована: Ноя. 25, 2023

In the present research, Livistona chinensis leaf extracts were utilized as reductants to bio-fabricate silver nanoparticles (LC-AgNPs) and this was followed by evaluation of their antioxidant, antibacterial, anticancer potential. Multiple parameters optimized for formation fidelity LC-AgNPs. The color shift reaction mixture from yellow dark brown confirmed LC-AgNPs formation. UV/VIS spectroscopy exhibited a surface plasmon resonance (SPR) band at 436 nm. Fourier transform infrared (FTIR) spectrum depicted phytochemicals in plant extract acting bio-reducers synthesis. XRD pattern presence showing peaks corresponding 2θ angle 8.24° (111), 38.16° (200), 44.20° (220), 64.72° (311). Zetasizer analysis size distribution intensity with mean value 255.7 d. Moreover, zeta potential indicated that AgNPs synthesized stable. irregular shape average 38.46 ± 0.26 nm found scanning electron microscopy. Furthermore, antioxidant examined using DPPH assay calculated be higher than extracts. IC50 values are 85.01 0.17 209.44 0.24, respectively. antibacterial activity investigated against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis well Staphylococcus aureus, maximum observed after 24 h P. aeruginosa. TPC1 cell lines compared extract. findings suggested could used agents cure free-radical-oriented bacterial oncogenic diseases.

Production of some Secondary Metabolites of Antibiotic Nature from Mycorrhizal Helper Bacteria (MHB) Associated with Conifers

Polish Journal of Environmental Studies, Год журнала: 2024, Номер 33(4), С. 4325 - 4334

Secondary metabolites are the special chemicals that organisms make for their own purposes.They not needed basic functions, but they have many uses in interactions with environment.They can protect themselves, communicate others, compete rivals, and cooperate partners.Mycorrhizal Helper Bacteria (MHBs) bacteria enhance plant-fungi partnership by supporting growth, nutrition, defense, modifying production use of secondary metabolites, which help them interact environment.In this study, morphological characterization isolation were carried out following serial dilution method, checked antimicrobial activity isolated strains biological screening.The best selected metabolite through shaking fermentation culture techniques; FTIR (Fourier transform infrared) spectroscopy grams' staining also out.Strain PW 2-3-1 showed highest activity, whereas strain AP 10-2-4 least against four bacterial strains, viz; Bacillus meurellus, subtilis, Acinetobacter rhizosphaerae, Escherichia coli.FTIR spectrum analysis presence C-H C-O stretches wavenumbers ranging from 500-3500 antibiotic nature.The application Mycorrhization be an encouraging method to achieve successful reforestation.It has been additionally recommended could detoxify impacts parasitic metabolites.
