The present study evaluates the potential of Sar gassum muticum (Sar) and Jan ia rubens (Jan) seaweeds for enhancing growth mitigating soil-salinity in chickpea (Cicer arietinum L.). Under control conditions, extracts improved which was attributed to their increasing photosynthetic pigments, K+ amino acids, particularly proline, comparison with water-sprayed control. Upon stress imposition, reduced NaCl concentration-dependent manner, principal component analysis (PCA) revealed Na+...
The green microalga Chlorella vulgaris was used as a test organism during this study for evaluation of the impact different heavy metal stress, Mn
LC-MS-assisted metabolomic profiling of the Red Sea-derived brown algae Sargassum cinereum “Sargassaceae” dereplicated eleven compounds 1–11. Further phytochemical investigation afforded two new aryl cresol 12–13, along with eight known 14–21. Both metabolites, 19, showed moderate in vitro antiproliferative activity against HepG2, MCF-7, and Caco-2. Pharmacophore-based virtual screening suggested both 5-LOX 15-LOX as most probable target linked to their observed activity. The enzyme assays...
Malaria is one of the most important infectious diseases worldwide. The causative severe forms malaria, Plasmodium falciparum, has developed resistances against all available antimalarial drugs. In present study, phytochemical investigation green seaweed Halimeda macroloba afforded two new compounds 1-2, along with 4 known ones 3-6. structures had been confirmed using 1& 2D-NMR and HRESIMS analyses. Extensive machine-learning-supported virtual-screening suggested cytochrome-C enzyme as a...
During our research on the diversity of diatoms and green microalgae from Egypt, four new-to-science, newly recorded, poorly known species were retrieved different Egyptian habitats. The new benthic diatom Halamphora shaabanii A.A. Saber, El-Sheekh, Levkov, H. Saber et Cantonati sp. nov., which could not be identified using currently available literature, was described high-conductivity, oasis lake Abu Nuss in El-Farafra Oasis, located Western Desert employing both light (LM) scanning...
Abstract This study investigates the potential of Tetradesmus obliquus for lipid accumulation under heavy metal stress and evaluates it’s aviability biodiesel production. We surveyed how different concentrations metals, including manganese (Mn), cobalt (Co), zinc (Zn), influence carbohydrate & protein, yield, fatty acid profiles T. cultures. Our results demonstrated that while content increased stress, extent was highly dependent on type concentration. Notably, algal culture treated with...
Our knowledge of the green macroalga Halimeda (Ulvophyceae, Chlorophyta) is still poor and underestimated from phytochemical pharmacological standpoints. Pharmacological therapeutic potentials chemically-diverse compounds derived different species genus are highly promising as antiviral, antimicrobial, cytotoxic, antiproliferative, cardioprotective, anti-inflammatory, anti-osteoarthritic, hypoglycemic, hepatoprotective neuroprotective agents. This review highlighted diverse properties in...
Jania rubens and Sargassum dentifolium aqueous extracts were used as a reducing agent for the synthesis of silver nanoparticles (Ag-NPs). The prepared Ag-NPs have two plasmon absorption bands at 440 nm 420 nm, with direct band gap 2.25 eV 2.38 Ag-NPs/J. Ag-NPs/S. respectively. From FTIR results, reduction has mostly been carried out by C=N, hydroxyl or sulfated polysaccharides groups present in J. S. dentifolium, TEM images shown that most particles are spherical shape no aggregations debris...
Background UV radiation and its impact on living organisms became an essential concern over the past three decades will be in years to come. So, present investigation was devoted examining of artificial UV-B accumulation amino acids MDA contents as well some antioxidant enzymes activities freshwater cyanobacterial species; Planktothrix cryptovaginata, Nostoc carneum Microcystis aeruginosa, one green alga; Scenedesmus acutus marine cyanobacterium; Microcystis.Methods The algal cultures were...
Background Global warming directly influencing ozone layer depletion, which eventually is increasing ultraviolet radiation penetration having far-reaching impacts on living biota. This particularly influences the primary producer microalgae are basic unit of food webs in aquatic habitats. Therefore, it necessary to concentrate research at this micro-level understand harmful impact increased UV-B ever before. Consequently, present attempt aimed focus influence growth criteria, photosynthetic...
The red seaweed Hypnea J.V. Lamouroux is a cosmopolitan genus of the family Cystocloniaceae. It has been used in folk medicine, especially eastern Asian countries. However, little literature highlighted phytochemical and pharmaceutical values its different species. In past centuries, until now, species have also widely utilized as main component food recipes because they are rich various bioactive compounds including polysaccharides, particularly 'κ-carrageenans', polyphenolics, vitamins,...
Abstract Ethanol extracts of Caulerpa racemose (Forsskål) J.Agardh, 1873, Dictyopteris acrostichoides (J.Agardh) Bornet, 1885, Halimeda opuntia (Linnaeus) J.V.Lamouroux, 1816, and Polycladia myrica (S.G.Gmelin) Draima, Ballesteros, F.Rousseau & T.Thibaut, 2010, were tested for their cytotoxicity against human hepatoma, breast adenocarcinoma, colon adenocarcinoma cell lines. displayed with IC 50 values 11.65, 9.28, 16.86 µg/ml, respectively, in comparison to doxorubicin as a positive...
Listeria monocytogenes is an important foodborne pathogen of public- and animal-health concern globally. The persistence L. in the dairy-processing environment has multifactorial causes, including lack hygiene, inefficient cleaning, improper disinfection practices.A total 300 dairy-product environmental samples were collected from dairy-cattle facilities local dairy shops vendors Qena, Egypt. Samples screened for incidence spp. to detect virulence determinants disinfectant-resistance genes....
