Antimicrobial resistance (AMR) has long been framed as an epidemiological and public health concern. Its impacts on the environment are unclear. Yet, basis for AMR is altered cell physiology.

Cement-free and cyanobacteria-based living building materials (LBMs) can be manufactured using microbially induced calcium carbonate (CaCO3) precipitation (MICP) technology, which is regarded as eco-friendly because of the absence CO2 gas emissions during manufacturing process. Here, we report that photosynthetic filamentous cyanobacterium Leptolyngbya boryana GGD precipitate substantial amounts CaCO3 with biofilm formation in our optimized medium. Compared to coccoid cells, cells have an extensive surface area efficiently agglomerate granular fill void spaces by forming bridging microstructures along precipitated LBMs, enhance mechanical properties LBMs. Regenerative LBMs possibly reconstructed old from parent without addition strain cells. The physicochemical hold promise valuable components for maintaining structural integrity

Eco-friendly reagents derived from plants represent a promising strategy to mitigate the occurrence of toxic cyanobacterial blooms. The use an amentoflavone-containing Selaginella tamariscina extract (STE) markedly decreased number Microcystis aeruginosa cells, thus demonstrating significant anti-cyanobacterial activity. In particular, Microcystis-killing fraction obtained pulverized S. using hot-water-based extraction at temperatures 40 °C induced cell disruption in both axenic and xenic M. aeruginosa. Liquid chromatographic analysis was also conducted measure concentration amentoflavone STE, supporting potential aeruginosa-specific killing effects STE. Bacterial community revealed that STE treatment led reduction relative abundance species while increasing 16S rRNA gene copy NIBR18 bloom samples isolated freshwater environment. Subsequent testing on bacteria, cyanobacteria, algae not for other taxa. Furthermore, ecotoxicology assessment involving Aliivibrio fischeri, Daphnia magna, Danio rerio found high doses immobilized D. magna but did impact organisms, there no change water quality. Overall, due its effective capability low ecotoxicity, aqueous represents practical alternative management

The number of cyanobacterial harmful algal blooms (cyanoHABs) has increased, leading to the widespread development prediction models for cyanoHABs. Although bacteria interact closely with cyanobacteria and directly affect cyanoHABs occurrence, related modeling studies have rarely utilized microbial community data compared environmental such as water quality. In this study, we built a machine learning model, multilayer perceptron (MLP), Microcystis dynamics using both bacterial weekly quality from Daechung Reservoir Nakdong River, South Korea. performance, indicated by R
