Furan derivatives are recognized for their diverse biological activities, particularly antimicrobial properties. In this study, three new furan were isolated from acid-treated Chrysanthemum indicum flowers. The structures elucidated using spectroscopic techniques and identified as methyl (E)-3-((5-(methoxymethyl)furan-2-yl)methylene)-4-oxopentanoate (1), (Z)-3-((5-(methoxymethyl)furan-2-yl)methylene)-4-oxopentanoate (2), (E)-3-(furan-2-ylmethylene)-4-oxopentanoate (3). These compounds evaluated antibacterial activity against Vibrio spp. Microcystis aeruginosa. Compound 3 showed the highest inhibition (63.5%) M. aeruginosa at 50 μg/mL, with 1 2 demonstrating lower activities (36.1% 58.3%, respectively). structural difference between 2, limited to double bond geometry, likely contributes varying efficacies. findings indicate that C. could be promising candidates applications, in aquaculture.

The global population increase during the last century has significantly amplified freshwater demand, leading to higher wastewater (WW) production. European regulations necessitate treating WW before environmental. Microalgae have gained attention for treatment (WWT) due their efficiency in remediating nutrients and pollutants, alongside producing valuable biomass. This study investigates phycoremediation potential of a Chlorella-like strain isolated from urban 600L-scale system under winter conditions. Experiments December 2021 February 2022 tested strain’s adaptability varying environmental conditions, particularly temperatures (min-max temperature range: −3.69 10.61 °C −3.96 17.61 February), its ability meet legal discharge limits. In December, low algal growth. Nitrates showed an RE about 92%, while ammonia slightly decreased (RE, 32%), phosphorous remained unchanged. February, mild increased density (33.3 × 106 cell mL−1) and, at end experiment, all were below limits with very high % (NH4+, 91.43; PO43− 97.32). Both trials E. coli RE, = 99%. highlights microalgae WWT importance considering seasonal variations when implementing these systems.
