Dietary dose-dependent effects of Ginkgo biloba leaf extract on growth, immunity, antioxidant status, and hepatic integrity in Nile tilapia

Abstract The increasing demand for sustainable alternatives to in-feed antibiotics has stimulated interest in phytogenic feed additives. This study investigated the dose-dependent effects of dietary Ginkgo biloba leaf extract (GBLE: 0, 6, 12, 18, and 24 g/kg diet) in Nile tilapia...

Marine Recombinant L-Asparaginase-MoO3 Nanocomposite as an Ecofriendly Antifouling Paint Formula

Marine biofouling poses significant economic and environmental challenges by increasing fuel consumption, accelerating material degradation, and facilitating the spread of invasive species. Environmentally benign antifouling technologies are therefore urgently needed following re...

Rapid degradation of sulfur-containing pollutants in water using potassium oximate through nucleophilic transformation with kinetic, mechanistic and antimicrobial evaluation

Abstract Sulfur-containing organic pollutants persist in industrial wastewater, particularly in petroleum refining effluents, where their chemical stability limits conventional treatment. Here, we report a rapid and efficient degradation strategy based on potassium 2,3-butanedion...

Mitigation of benzo[a]pyrene-induced toxicity in Nile tilapia using Phoenix dactylifera seed biochar

Abstract Benzo[a]pyrene (BaP), a common polycyclic aromatic hydrocarbon, poses an increasing threat to aquaculture systems because of its detrimental effects on fish health-related physiological traits. The current study investigated the prospective use of Phoenix dactylifera see...

Multi-approach integrating water quality variables, remote sensing, eDNA and histopathology for assessing the impact of microbial pollution on Nile Tilapia from Kitchener Drain, Northern Egypt

Abstract This study integrated environmental DNA (eDNA) metabarcoding, conventional bacteriology, histopathology, water quality variables, and remote sensing indices to investigate how environmental gradients are associated with pathogen-associated taxa communities and influence...

Oral Co-supplementation with Pediococcus pentosaceus Probiotic and Enteric Polymeric Phycocyanin Nanoparticles Mitigates Aging-Related Biomarkers in Male Wistar Rats: A Preclinical Investigation

Abstract C-phycocyanin (C-PC) is a promising anti-aging nutraceutical due to its antioxidant and anti-inflammatory properties; however, its instability under acidic conditions limits its efficacy, necessitating advanced formulation strategies. This study evaluated the anti-aging...

Development of probiotic yoghurt fortified with high-purity Chlorella vulgaris-derived lutein and its nanoencapsulated form for enhanced stability and functional efficacy

Lutein delivery from microalgae into probiotic yogurt is limited by poor aqueous solubility, oxidative degradation during fermentation, and reduced bioaccessibility. This study developed a scalable synbiotic yogurt fortified with high-purity lutein (92%, HPLC-confirmed) extracted...
