Antibiotic resistance genes (ARGs) have exhibited significant ecological concerns, especially in the urban water that are closely associated with human health. In this study, with presence of exogenous Chlorella vulgaris-Bacillus licheniformis consortium, most of the typical ARGs and MGEs were removed. Furthermore, the relative abundance of potential ARGs hosts has generally decreased by 1-4 orders of magnitude, revealing the role of algal-bacterial consortium in cutting the spread of ARGs in urban water. While some of ARGs such as macB increased, which may be due to the negative impact of algicidal bacteria and algal viruses in urban water on exogenous C. vulgaris and the suppression of exogenous B. licheniformis by indigenous microorganisms. A new algal-bacterial interaction might form between C. vulgaris and indigenous microorganisms. The interplay between C. vulgaris and bacteria has a significant impact on the fate of ARGs removal in urban water.
抗生素抗性基因（ARGs）表现出显著的生态问题，尤其是在与人类健康密切相关的城市水中。在本研究中，由于存在外源小球藻-地衣芽孢杆菌联合体，大部分典型的 ARGs 和 MGEs 被去除。此外，潜在 ARGs 宿主的相对丰度普遍减少了 1-4 个数量级，揭示了藻类-细菌联合体在阻止 ARGs 在城市水中传播的作用。虽然有些 ARGs 如 macB 增加了，这可能是由于城市水中的杀藻细菌和藻类病毒对外源小球藻的负面影响，以及土著微生物对外源地衣芽孢杆菌的抑制作用。小球藻和土著微生物之间可能形成一种新的藻类-细菌相互作用。小球藻和细菌之间的相互作用对城市水中 ARGs 去除的命运有重大影响。
