“…Bayberry tannin (BT), composed of benzene rings and a variety of phenolic groups (molecular structure in Figure S1), allows for multiple molecular interactions with various antibiotic molecules, providing a new possibility to realize efficient removal of antibiotics. − Broad-spectrum antibiotics were effectively removed by PMAC (Figure a), which was conducted by the addition of polyphenol and metal ions consecutively in sequence (Figure b). When BT was added to wastewater, multiple noncovalent interactions (electrostatic interaction, hydrophobic interaction, hydrogen bond, and π–π interaction) occurred, through which the antibiotics molecules were captured to form phenolic–antibiotic nanocomplexes.…”

Ubiquitous antibiotics threaten human health and ecosystem sustainability, and existing removal strategies, especially conventional multistep water treatments, are primarily limited by the antibiotic-specific removal capability. Here, we explore the natural biomass, plant polyphenols, in the capture of various antibiotics with a facile treatment�polyphenol-mediated antibiotic-independent supramolecular coagulation (PMAC). The PMAC shows a superior performance in removing five tetracyclines and quinolones (up to 98.54%), even under complex environmental parameters, including different pH, the presence of inorganic particles and ionic strength, and the presence of conventional colloid-associated contaminants. Our mechanistic studies suggested that PMAC is capable of exerting multiple molecular interactions with various antibiotics, and the coordination-driven selfassembly further destabilizes the phenolic−antibiotic nanocomplexes, enabling an antibiotic-independent coagulation. Collectively, the combination of efficient remediation with inexpensive biomass suggests a simple and scalable method for the sustainable removal of antibiotics. Our strategy shows great promise as a cost-effective, facile approach to eliminate antibiotics capable of being integrated into the currently existing water treatment systems.

Chinese bayberry (Myrica rubra Sieb. et Zucc.) fruit (CBF) is widely growing in eastern Asia, mainly in China. CBFs contain a high number of polyphenols, especially anthocyanins. However, CBF can be easily damaged and cannot be stored for more than 3 days at 20–22 °C and 9–12 days at 0–2 °C. Thus, this review explores the potential options for the long-term preservation and consumption of CBFs, as well as the importance of CBF by-products. The review also addressed the biological activity of CBFs and their food products. The consumption period of CBF can be increased by employing a variety of processing techniques, including rapid freezing, drying, juicing, making wine and vinegar, and adding it to meals. Additionally, oil and bioactive substances can be extracted from the CBF by-products, such as kernel and pomace. The greatest options to extend the duration of CBF ingestion are thought to be CBF powder, juice, and wine. Furthermore, CBFs and their derivatives exhibit many biological activities such as antibacterial, anticancer, antidiabetic, and antioxidant properties. The two biological activities that were most potent were antidiabetic and antioxidant. However, more biological research, particularly clinical-based research, is advised to investigate the potential health benefits of CBF and its products.
