Potential of Salvinia biloba Raddi for the remediation of water polluted with ciprofloxacin: removal, physiological response, and root microbial community
This paper investigated the removal amount of Ciprofloxacin (CIP) by Salvinia biloba Raddi (S. biloba) under various conditions, the physiological response under different CIP concentrations, the influence of CIP on the root microbial community structure of S. biloba, the possible metabolic pathways and removal mechanism. The results showed that under 4 mg/L CIP, the removal rate of CIP was 98%. Under different CIP concentration conditions, low CIP concentration promoted the growth of S. biloba, while high CIP inhibited the growth of S. biloba and S. biloba was exposed to different degrees of oxidative stress. CIP affected root microbial community diversity and changed microbial community structure. Five possible degradation pathways were proposed through the determination of intermediate metabolites. According to mass balance calculations, biodegradation was the most critical degradation pathway. This study demonstrated the potential use of S. biloba for treating CIP-contaminated water and provided insights into the mechanisms of plant-based antibiotic degradation.
期刊介绍:
The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
