Zanthoxylum bungeanum residue has attracted increasing attention owing to its antibacterial effect, which presents potential as novel antimicrobial agents for the management of algal blooms. In this study, ability Z. extract control blooms been firstly verified. Then, response surface methodology was employed optimize flavonoids yield, primary component in extract, and underlying photosynthetic inhibition mechanisms on Tetrodesmus obliquus investigated. Results showed that highest yield total increased 4.08% when extraction conditions were a liquid-to-solid ratio 10:1, ethanol concentration 60%, temperature 80°C, time 30 min. Meanwhile, treatment with at doses 40.0 mg/L significantly decreased Fv/Fm PIabs values T. by 24.36 88.87% 50 h, respectively. The added induced damage multiple levels physiological biochemical processes cells, including reduced electron transport capability, disrupted energy transfer photosystem II, disruption OEC structure, altered distribution PSII reaction center. To our knowledge, study first verification residue’s algicidal potential, these findings contribute deeper understanding allelopathic offer valuable insights

Zanthoxylum bungeanum leaves were regarded as a waste byproduct for long period of time, yet their functional components presented potential novel antimicrobial agents. However, effectiveness in controlling algal blooms remains unexplored. In this study, the inhibition effect Z. leaf extracts on was firstly demonstrated, and flavonoid profiles extract identified using non-targeted metabolomics analysis. Then, response surface methodology performed extraction to further evaluate feasibility industrial application. Specifically, effects cell density, photosynthetic efficiency, antioxidant activity Tetrodesmus obliquus investigated. The results showed that yield flavonoids from reached 6.85% under optimized conditions an ultrasonic power 600 W, LSR 20:1 mL/g, ethanol concentration 77.5%, duration 18 min, temperature 80 °C, which significantly decreased Fv/Fm PIabs values by 54.60% 98.22%, respectively, after exposure T. 40.0 mg/L 66 h. Meanwhile, treatment with at dose generated T-AOC 4.0 times higher than control without addition extracts. These suggest could be used development potentially effective biological algicides. Our study provides data support algicides realizes resource application waste, achieving synergistic outcome both economic ecological benefits.

Prymnesium parvum is a harmful alga found in brackish waters worldwide whose toxins can be lethal to aquatic organisms. Established field methods control blooms of this species, however, are unavailable. Earlier studies showed that various extracts giant reed (Arundo donax) suppress P. growth and ellipticine, an allelochemical present reed, potent algicide against species. The unintended effects products on nontarget organisms, not fully understood. This study determined the leachate (aqueous extract dried chips) ellipticine green microalga Chlorella sorokiniana; survival reproduction planktonic crustacean Daphnia pulex; hatching success, larval survival, swimming behavior teleost fish Danio rerio. Leachate made with 3 g chips L−1 was lethally toxic D. pulex, stimulated C. sorokiniana growth, impaired rerio behavior. at 1 suppressed had moderate pulex reproductive output, no Ellipticine 0.01 mg irreversibly inhibited acutely but reversibly slightly delayed reproduction, These observations suggest when applied appropriate concentrations, natural derived from used as tools specifically minimal
