“…Long-term exposure to electroplating wastewater can have a series of serious health effects on humans, including kidney failure, thyroid dysfunction, insomnia, fatigue, and rheumatoid arthritis, impacting both the circulatory and nervous systems, causing gastrointestinal mucosal irritation, and leading to lung cancer [3]. Wastewater from the electroplating industry also contains multiple highly concentrated heavy metals such as cobalt (Co), copper (Cu), chromium (Cr), mercury (Hg), iron (Fe), nickel (Ni), zinc (Zn), and metalloid arsenic (As) [4,5]. China has approximately 15,000 electroplating companies, generating over 2.7 billion gallons of wastewater annually [6,7].…”

Heavy metal pollution poses significant environmental challenges, and understanding how plants and endophytic bacteria interact to mitigate these challenges is of utmost importance. In this study, we investigated the roles of endophytic bacteria, particularly Chryseobacterium and Comamonas, in Leersia hexandra Swartz (L. hexandra) in response to chromium and nickel co-pollution. Our results demonstrated the remarkable tolerance of Chryseobacterium and Comamonas to heavy metals, and their potential to become dominant species in the presence of co-pollution. We observed a close relationship between these endophytic bacteria and the significant differences in metabolites, particularly carbohydrates, flavonoids, and amino acids in L. hexandra. These findings shed light on the potential of endophytic bacteria to promote the production of aspartic acid and other metabolites in plants as a response to abiotic stressors. Furthermore, our study presents a new direction for plant and bioremediation strategies in heavy metal pollution and enhances our understanding of L. hexandra’s mechanisms for heavy metal tolerance.
