Mechanisms of action attributed to feed additives are continuous research interest, increasing our knowledge about the side effects (direct or indirect) their application. The primary role organically modified clinoptilolite is bind multiple polar and non-polar mycotoxins contaminating remove them during digestion process through feces, therefore preventing adsorption consequences mycotoxicosis on fish health. However, it not fully understood if this binding can influence bacterial communities in digestive tract possibly other organs, as well aquatic environment. Therefore, study, Nile tilapias (Oreochromis niloticus) (average weight: 30 ± 2 g; n = 48) were simultaneously exposed low-level (AFB1 40 µg/kg, FB 600 ZEN 50 DON 150 µg/kg) added diet, with without supplementation commercially available additive (MinazelPlus®, g/kg). After 42 days exposure, gill tissue, water collected, DNA was extracted from samples. Results RT-PCR analysis have revealed significant changes microbiomes different groups, most prominently mycotoxin-exposed fish.

A wide range of EOPs are now being detected in surface water and groundwater resources due to recent historical anthropogenic activities (Vashistha, 2022). These pollutants enter the environment through several pathways such as industrial effluent discharge, agricultural runoff, wastewater treatment plants (WWTPs) discharge improper waste disposal (Kuchangi et al., 2023;Shah, 2021). Due their into environment, can harm wildlife, ecosystems, possibly humans (Zhou 2024). Thus, a variety methods have been reported for removal EOPs, particularly using adsorptive photocatalytic degradation utilizing nanomaterials (Mashile 2023;Paumo This Frontiers Chemical Engineering article collection aimed highlight development effective or technologies well application bio-based sorbents monitoring occurrence systems. total four papers contained herewith including two comprehensive reviews research articles related adsorbents photosensitizers water.The collected work represented contributions from leading groups worldwide offering insights direction various photocatalysts.
