Pharmaceuticals and personal care products (PPCPs) are emerging pollutants in aquatic environments, posing significant ecological risks. Cyanobacteria, as primary producers ecosystems, crucial for ecosystem health. Understanding the toxicological effects metabolic mechanisms of PPCPs cyanobacteria is essential evaluating environmental risks bioremediation feasibility. This study reveals that while both sulfamethoxazole (SMX) triclosan (TCS) inhibit algal growth by reducing photosynthetic pigment synthesis activity, Synechocystis sp. PCC 6803 shows markedly different sensitivities to these compounds. The 72-h EC50 values TCS SMX were 14.55 μg/L 19.74 mg/L, respectively. Despite differences, achieved removal rates 89.58% 87.60% SMX. Biodegradation was mechanism both, but also involved biological adsorption bioaccumulation, absent hydrophilic Metabolic pathway analysis identified glycosyltransferase-mediated reactions key metabolism, N4-hydroxylation-SMX (m/z 270) a critical intermediate degradation. Notably, sll1732 gene found play pivotal role research offers insights into interactions between PPCPs, highlighting its potential environmentally sustainable bioremediation.

Oxidative stress mechanisms underlying temporal hormesis effects induced by binary antibiotic mixtures on Scenedesmus obliquus

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 291, С. 117889 - 117889

Опубликована: Фев. 1, 2025

The hormesis effect has gradually become a research focus in environmental science and toxicology due to its unique phenomenon of low-concentration stimulation high-concentration inhibition. combined toxicity antibiotics their regulatory effects on microorganisms are areas that warrant significant attention. In this study, doxycycline hydrochloride (DXC), sulfamethoxazole (SMX) sulfamethazine (SMZ) were used as the objects, Scenedesmus obliquus was indicator organism study action laws at different exposure times (4d 8d). toxic antibiotic mixtures with comprehensively evaluated from aspects growth inhibition, photosynthesis index antioxidant enzyme activity. results showed 11 rays produced effect, value 8th day greater than 4th day. Through prediction toxicity, it found type intensity affected by mixture composition, time concentration. Hormesis is caused regulation photosynthesis, activation defense system, gene expression, change cell membrane permeability. This provides theoretical basis for understanding effect.
