“…its rhizomes are externally blackish in color and white inside with a characteristic odor 16,17 . Watery and ethanol crude extracts of C. rotundus rhizomes showed significant effects against gram-negative 18 and gram-positive bacteria, Candida albicans 19,20 and fungal pathogens 21 . On the other hand, aqueous extract of C. longous has activity against parasitic worms 22 .…”

The synthesis of metallic nanoparticles has become an important issue in recent decades due to their various beneficial and unique properties and biomedical and industrial applications 1. Nanotechnology is seeking to synthesize nanoparticles have substantial biomedical applications because of their unique characteristics and their green nature due to using some medicinal plants as ABSTRACT The object of this work is biosynthesizing AgNPs from extracts of Cyperus sp. galingale rhizomes, studying their characteristics using UV-visible spectroscopy, AFM, SEM, FTIR, and EDX analyses and testing their anticancer activity (in vitro) against L20B cell line. Biosynthesizing AgNPs using various plants is considered eco-friendly, cheap, energy saving and reproducible compared with non-green methods. UV-Visible spectrum checked the surface plasmon resonance of AgNPs at 410-420 nm. FT-IR exhibited that the presence of carbonyl and hydroxyl groups in the extract of Cyperus sp. can reduce and stabilize AgNPs. EDX, SEM, and AFM analyses were applied to confirm the nature, morphology and topography of the biosynthesized AgNPs. AgNPs are spherical or irregular in shape with the average diameter of hot extract-AgNPs is 56.31 nm in comparison with cold extract-AgNPs is 92.53 nm. The hot extract-AgNPs paly a suitable role against mouse cell line (L20B) which have receptors for polioviruses better than the cold extract-AgNPs.

“…Even at low concentrations, the plant extract suppresses ampicillin-resistant S. aureus in synergism with ampicillin (Cheypratub et al, 2018). The polar fraction of C. rotundus rhizomes is antifungal against a strawberry fungal pathogen that the non-polar fraction failed to suppress (Özdemir & Erincik, 2015). According to studies, these bioactive compounds have profound antibacterial and antifungal activities against human infections (Cunha et al, 2018;Zhu, 2020).…”

Freshwater aquaculture contributes ~55% of the total fish output in India (Dey, Financial Express, 14 February 2020). With the increasing demand for aquatic food products and supply failing to meet the requirements from capture fisheries, the necessity for intensive aquaculture has become apparent (Bueno et al., 2017;Kato &Freitas, 2015;Moffitt & Cajas-Cano, 2014). Despite this, there is still a significant gap between production and commercialization due to mass mortality caused by bacterial diseases (

Biopesticides, which consist of antagonistic microorganisms, or the bioactive compounds they produce offer attractive alternatives to synthetic agrochemicals as a means of reducing plant diseases in crop production systems. In our previous study, a strain of Pseudomonas entomophila 23S was reported to have a strong antagonistic activity toward Clavibacter michiganensis subsp. michiganensis (Cmm), a pathogen of tomato bacterial canker disease, which causes serious damage to the tomato production industry. This study focused on purification and characterization of the anti-Cmm compound(s) produced by P. entomophila 23S. The cell-free supernatant was first subjected to butanol extraction, fractioned by solid-phase extraction (SPE), and purified by high-performance liquid-chromatography (HPLC). The semi-preparative purified compounds retained anti-Cmm activity. These compounds were then characterized by liquid chromatography coupled with high-resolution tandem mass spectrometry (LC-HRMS/MS) and nuclear magnetic resonance (NMR). Two anti-Cmm compounds, C15H16N2O and C16H18N2O, were isolated by this procedure. From the LC/MS spectra, the compounds were predicted to have an isoquinoline ring, the presence of which was confirmed by NMR. The compounds differed with respect to the presence of a methyl group in a side chain. In addition, P. entomophila 23S grown in different culture media produced the greatest amounts of these anti-Cmm compounds when in Nutrient Broth (NB), where bacterial growth was the slowest. NB composition is more favorable in stimulating P. entomophila 23S to produce higher amounts of these anti-Cmm compounds.
