20.500.12556/RUL-177205 Silicon as a potential bioremediation agent for mitigating aluminum toxicity in aquatic microalgae implications for sustainable agricultural ecosystems Silicij kot potencialno bioremediacijsko sredstvo za ublažitev toksičnosti aluminija v vodnih mikroalgah: posledice za trajnostne kmetijske ekosisteme Heavy metal pollution in agricultural and aquatic ecosystems poses significant threats to microorganisms essential for ecological balance. Microalgae, as primary producers, are particularly vulnerable to such contaminants while being vital components of sustainable agricultural systems. This study investigated the comparative effects of silicon (Si) and aluminum (Al) on three economically important microalgae species: Chlorella vulgaris, Haematococcus pluvialis, and Tetraselmis suecica. Microalgae cultures were exposed to varying concentrations of aluminum (1, 10, and 100 mg/L) and silicon (100, 150, and 200 mg/L) for three weeks under controlled conditions. Aluminum treatment resulted in significant concentration-dependent growth inhibition (37-62%) and decreased total chlorophyll content, with observable morphological alterations including cell swelling and chlorophyll degradation. Conversely, silicon treatment exhibited minimal adverse effects on microalgal growth, biomass, and chlorophyll content compared to both Al-exposed and control groups. These findings suggest that silicon could serve as an effective protective agent against aluminum toxicity in aquatic ecosystems, with potential applications in agricultural water management and bioremediation of metal-contaminated irrigation systems. The study contributes to understanding metalloid interactions in aquatic microorganisms, supporting sustainable agricultural practices through improved water quality management and protection of beneficial microalgae in farm ecosystems. silicon aluminium toxicity microalgae physiology aquatic ecosystems agricultural water quality silicij toksičnost aluminija fiziologija mikroalg vodni ekosistemi kakovost kmetijske vode true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-17 13:19:05 2025-12-17 13:19:12 2025-12-28 04:17:01 0000-00-00 00:00:00 2025 0 0 10 str. no. 4 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2025.121.4.22996 261876739 ISSAAD+et+al.+(J)_(1).pdf ISSAAD+et+al.+(J)_(1).pdf 1 4C51E028589991D1EAC03E854A0AD4C7 4cda8f3480320b9213fc8296f8958968fbb0bccfd311bb1c1d7391d223b21934 58252a3b-db42-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224118 https://journals.uni-lj.si/aas/article/view/22996/19892 1 287d5efe-db42-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224116 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
