Abstract Textile wastewater contains large quantities of azo dyes mixed with various contaminants especially heavy metal ions. The discharge effluents containing methyl orange (MO) dye and Cu 2+ ions into water is harmful because they have severe toxic effects to humans the aquatic ecosystem. dried algal biomass was used as a sustainable, cost-effective eco-friendly for treatment textile wastewater. Box–Behnken design (BBD) identify most significant factors achieving maximum biosorption MO...
The present study aims at solving the problem of stagnant water due to receiving sewage in a lake Eastern Jeddah, using state art safe techniques. Samples were collected from lake, then treated magnetic fields with different intensities two states, static and shaking, for 30 days. Hence, physical chemical properties samples measured, addition their bacterial content. In both cases increasing flux density caused clearness, relative increase pH value remarkable decrease its odor electric...
Abstract A large number of industries use heavy metal cations to fix dyes in fabrication processes. Malachite green (MG) is used many factories and aquaculture production treat parasites, it has genotoxic carcinogenic effects. Chromium the a global toxic metal. Face centered central composite design (FCCCD) been determine most significant factors for enhanced simultaneous removal MG chromium ions from aqueous solutions using marine alga Enteromorpha intestinalis biomass collected Jeddah...
Purpose: This study was designed to determine the potential effect of nanoencapsulated bioactive compounds from different natural sources on human pancreatic cancer. Background: Pancreatic cancer carries highest fatality rate among all cancers because its high metastatic and late presentation at time diagnosis. Hence there is a need for improved methods prevent treat it. Natural products, such as 3, 3′-diindolylmethane (DIM) ellagic acid (EA) demonstrated anticancer efficacy against various...
Paecilomyces variotii xylanase was, produced in stirred tank bioreactor with yield of 760 U/mL and purified using 70% ammonium sulfate precipitation ultra-filtration causing 3.29-fold purification 34.47% activity recovery. The enzyme purity was analyzed on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirming its monomeric nature as single band at 32 KDa. Zymography showed xylan hydrolysis the same band. had optimum 60 °C pH 5.0. stability range 5-9 temperature up...
There are two major problems in the world, fuel deficiency and environmental pollution by fossil fuels. Microalgae regarded as one of most feasible feedstocks for manufacturing biofuels used degradation spills. The present study was possessed to investigate ability green alga Chlorella vulgaris, blue-green Synechococcus sp, its consortium grow degrade hydrocarbon such kerosene (k) with different concentrations (0, 0.5, 1, 1,5%), also using algal biomasses produce biofuel. growth estimated...
Background and Aim: Natural antioxidants are crucial for preserving enhancing the health, survival, reproduction, reproductive function of poultry. Phycocyanin (PC) is a natural blue food colorant with various health benefits. The aim this study was to extract Arthrospira platensis phycocyanin (ApPC) from A. using simple economical methods investigate impact phytocyanin supplementation on performance fatty amino acid profiles broiler chicks. Materials Methods: PC extracted by freezing...
The eco-friendly method of producing copperـoxide nanoparticles through the use okra fruit extract is a simple, economical, rapid, and sustainable technique. resultant (CuO NP) were analyzed with several analytical methods, such as UV-vis spectroscopy, FourierـTransform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Zeta potential, TransmissionـElectron Microscopy (TEM) EnergyـDispersive X-ray (EDX) analysis. CuO NP exhibited maximum absorbance at 381 nm. formation was further...
The biosynthesis of bimetallic nanoparticles using plant extracts has garnered significant attention due to their eco-friendly and cost-effective nature. This study aimed biosynthesize magnesium oxide-zinc oxide nanocomposite (MgO-ZnO nanocomposite) Pluchea indica leaf extract for the first time, with a focus on characterizing its physicochemical properties evaluating biological activities. biosynthesized MgO-ZnO was fully characterized, revealing an absorbance peak at 300 nm UV-vis...
Doxorubicin (Dox) induces senescence in numerous cancer cell types, but these senescent cells relapse again if they are not eliminated. On this principle, we investigated the apoptotic effect of thymoquinone (TQ), active ingredient Nigella sativa seeds and costunolide (COS), Costus speciosus, on colon (Sen-HCT116) breast (Sen-MCF7) lines reference to their corresponding proliferative rapidly eliminate cells. The markers Sen-HCT116 Sen-MCF7 were determined by a significant decrease...
Calotropis procera (C. procera) is a wild shrub that medicinal plant found in abundance throughout Saudi Arabia. In this study, we investigated the phytochemical composition and antigenotoxic properties of ethanolic extract C. procera, addition to antimicrobial activity its rhizospheric actinobacteria effects against pathogenic microorganisms. Soil-extract medium supplemented with glycerol as carbon source starch-casein agar was used for isolation from rhizosphere. From plant, total 31...
