Study on quinolone accumulation and growth inhibition induced by quinolone levels of hydroponics

Abstract

Residual antibiotics can enter soil and water bodies through organic fertilizers with food safety risk via plants absorption, while how do plant growth and quinolone accumulation respond to residual antibiotics levels in soil or water is not clear. Hydroponic experiment in greenhouse was conducted with floating seedlings of tobacco as model plant to investigate the responses of quinolone antibiotics accumulation and plant growth to different levels of ciprofloxacin (CIP) and norfloxacin (NOR). Results showed that CIP and NOR inhibited the growth of tobacco seedlings. The plant height, stem circumference, maximum leaf width, and maximum leaf area of tobacco seedlings were significantly decreased. So as to the plant biomass of leaves, stems, and roots. Accumulation of CIP in the tobacco seedlings in the T3 was 1.1 times that of the tobacco seedlings in the T1, NOR in the T4 was 1.2 times that of the tobacco seedlings in the T1. And the higher the concentration, the more significant the inhibitory effect. Both antibiotics can be absorbed and accumulated by tobacco seedlings. Additionally, the inhibitory effect of CIP was greater than that of NOR.

Removal of Antibiotic Emerging Pollutants: An Overview

“…This type of material is highly abundant in soil and sediments, allowing the removal of different organic compounds [88], so these materials are important because they influence the transport of pollutants through the environment (Wu et al 2013) [89]. One of the advantages of using clay materials in removal processes is that it is an economical material with a high capacity to remove organic and inorganic pollutants [90]. One of its important characteristics, in addition to being one of the more abundant adsorbents in nature, is that it has a high ion exchange capacity, high specific surface area, and good colloidal dispersion, making these materials good for the treatment of wastewater containing organic and inorganic compounds, among others [91][92][93].…”

Effects of Ciprofloxacin-Oxytetracycline Compounds on Tobacco Seedling Growth in Hydroponices

“…At present, antibiotics play an important role in livestock and poultry breeding and are mostly used in the treatment of bacterial diseases and feed (Timothy et al, 2007;Yakhkeshi et al, 2012). Commonly used antibiotics are tetracyclines, quinolones, sulfas, macrolides and β-lactams (Wang et al, 2020(Wang et al, , 2021a.…”
