The increase in antibiotic resistance related to microbial biofilms creates an urgent need search for alternative and active antimicrobial agent. Recently, nanoparticles have gained considerable attention from scientists due their potent activity. In the present study, two endosymbiotic actinomycete strains were isolated marine sponge Crella cyathophora by surface sterilization incubation of pieces on culture media selective actinobacteria. filtrate extracts, including bacterial supernatants...
Abstract This study investigated the impacts of water application a commercial Bacillus species probiotics, SANOLIFE®PRO-W (containing subtilis and B. licheniformis ), on quality, digestive enzymes, growth performance, antioxidants, innate immunity, body composition, resistance whiteleg shrimp against Fusarium solani infection. A total 240 animals (2.00 ± 0.07 g) were stocked into twelve 1-m 3 concrete ponds divided four triplicate treatments. For 56 days, rearing was supplemented with...
Abstract Alginate–zinc oxide (Alg–ZnO) biocomposite was synthesized and tested as a chromium ions Cr(VI) adsorbent for environmental applications. Alg–ZnO prepared by the interaction between sodium alginate biopolymer zinc nanoparticles (ZnO–NPs), modified wet chemical method. The solid adsorption characteristics of were characterized Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–Vis spectroscopy. Adsorption isotherms on...
Abstract The growing spread of infectious diseases has become a potential global health threat to human beings. According WHO reports, in this study, we investigated the impact co-cultivating isolated endophytic fungus Aspergillus sp. CO2 and Bacillus COBZ21 as method stimulate production natural bioactive substances. (GC/MS)-based metabolomics profiling two sponge-associated microbes, COBZ21, revealed that co-culture these isolates induced accumulation metabolites were not traced their...
Abstract The use of phytobiotic as functional feed additives is a promising inducer for growth performance and immune response in the Pacific whiteleg shrimp ( Litopenaeus vannamei ). It can be also commercially applied combination with chemotherapeutic agents vaccines. This study was carried out to evaluate commercial additive, Sanacore® GM, containing vegetable fatty acids inactivated Saccharomyces cerevisiae herbal extracts , on growth, body composition, non-specific response, antioxidant...
Abstract The therapeutical applications of ornamental plants have been categorized to be a great effectiveness in multiple industries from ancient times until present days. Pluchea dioscoridis is widely known Egyptian wooden plant that has extensively applied for different medicinal purposes. In this study, LC-ESI-MS/MS analysis the potent antimicrobial ethyl acetate and n -butanol extracts P. leaves led identification 28 21 compounds, respectively. identified compounds were as phenolic...
Abstract Green synthesis of nanomaterials is the most recent trend in nanotechology because it synthesized highly valuable compounds (nanomaterials) from wastes to reduce negative impact these environment. The aim this study was isolate and purify common mycotoxin, aflatoxin producing fungi Maize soybean grains which considered as great economical importance both animal human feed. In addition green a-Al 2 O 3 cans detect its antifungal effect on isolate’s growth at different concentrations....
Schistosomiasis is one of the most deleterious parasitic diseases in world and it transmitted by aquatic snails. Consequently, there a continuous need to search for new molluscicides control The present study aimed evaluate molluscicidal activity two bacterial diethyl ether extracts against adult Biomphalaria alexandrina indicated that LC50 LC90 values were 193.734 280.670 mg/L Bacillus aerius extract 88.814 103.653 toyonensis B. snails after 48 h exposure. After 21-day chronic exposure...
During the last decades, technologies for agricultural drainage water remediation had been widely explored to oppose arising intimidation of their pollutants on health, biotas and farming sustainability. The present study targeted augment competence inorganic faecal coliforms from using different types clay minerals. Kaolinite, Bentonite, Ball Aswan were used either solely or in amalgamation with some biological premeditative amendments (cultures Phosphate dissolving Bacteria (PDB) and/or...

he goal of this study was to see how adding Nigella sativa (NE) and curcumin extracts (CE) separately in combination affected broiler performance, blood biochemical markers, antioxidant status intestinal microbiota.Four experimental diets formulated: Control, NE (600 ppm), CE mix (300 ppm + 300 CE).A total 240 chicks at 11 days age were assigned the four dietary treatments 60 each.The results showed that addition NE, or significantly enhanced (P<0.05)body weight gain feed conversion ratio...
The objective of this study is to assess the effectiveness different techniques employed in remediating contaminated soil and wastewater ecosystems ensure safety tomato fruits (Solanum lycopersicum L. var. cerasiforme) cultivated these environments. Three biochemical T1-T3, besides two controls CCU CCT, were used remediate using rock phosphate, elemental sulfur, bentonite, phosphate-dissolving bacteria, Thiobacillus sp. agricultural drainage water was remediated by a down-flow hanging sponge...
In a soil ecosystem irrigated with low-quality water out at El-Rahway village, Giza Governorate, Egypt, completely randomized field trial was carried to assess the suitability of some biochemical remediation technologies on minimizing inorganic contaminants hazards, their bioavailability as well relationship between potential toxic elements (PTEs) distribution in remediated ecosystem, index (BI) and pollutants uptake by cultivated hyperaccumulated plants. Turnip Brassica rapa radish Raphanus...
Fungal peroxidases are oxidoreductases that utilize hydrogen peroxide to catalyze lignin biodegradation.PER-K (peroxidase synthesis codon gene) was transformed from Aspergillus niger strain AN512 deposited in the National Center for Biotechnology Information with accession number OK323140 Escherichia coli (BL21-T7 YEp356R recombinant plasmid) via calcium chloride heat-shock method. The impact of four parameters (CaCl2 concentrations, centrifugation time, shaking speed, growth intensity) on...
This research focused on isolating and purifying the most frequent mycotoxin, aflatoxin-producing fungi from maize soy-bean grains, which are of enormous economic worth as animal human feed. Alpha gamma aluminum oxide nanoparti-cles ( γ-Al2O3 NPs) were also green generated cans. XRD, HRTEM, ATR-FTIR utilized to analyze structure morphology NPs.
