Dynamics of neutralizing antibodies against COVID-19 Omicron subvariants following breakthrough infection in southwest China between December 2022 and April 2024.

From December 2022 to January 2023, the SARS-CoV-2 Omicron BA.5/BF.7 variant significantly impacted mainland China.

Insight into the roles of soluble, loosely bound and tightly bound extracellular polymeric substances produced by Enterobacter sp. in the Cd and Pb biosorption process: Characterization and mechanism.

Extracellular polymeric substances (EPSs) are macromolecular polymers formed by metabolic secretion, and they have great potential for removing heavy metal (HM) ions from the aquatic phase. In this study, the contributions of soluble EPSs (S-EPSs), loosely bound EPSs (LB-EPSs) and tightly bound EPSs (TB-EPSs) secreted by Enterobacter sp. to Cd and Pb adsorption were analyzed.
