Antibiotic Removal by Three Promising Microalgae Strains: Biotic, Abiotic Routes, and Response Mechanisms

Water Air & Soil Pollution, Journal Year: 2024, Volume and Issue: 235(9)

Published: Aug. 12, 2024

Abstract Microalgae represent an alternative to conventional wastewater treatment, potentially improving antibiotic removal and offering a solution combat the spread of antimicrobial resistance. Through batch assays, this study investigates routes for using three strains ( Chlamydomonas acidophila , Auxhenochlorella protothecoides Tetradesmus obliquus ). Using mixtures ciprofloxacin, clarithromycin, erythromycin, metronidazole, ofloxacin, sulfamethoxazole, trimethoprim at concentrations simulating composition, it also assesses effects on microalgae physiology. The primarily removed antibiotics through rapid biosorption, achieving up 91.5% specific ones like ciprofloxacin. T. C. showed efficacy, with total removals 37.2% 49.3%, respectively. Over time, A. demonstrated highest active efficiency, eliminating 22.1% antibiotics, notable 67.6% sulfamethoxazole. Abiotic degradation hydrolysis photolysis contributed erythromycin (34.7% 96.7%), showing pH-dependent photolysis. However, algae induced shading effect, reducing photolytic hydrolytic antibiotics. were inhibited by whereas 30.6% growth rate increase. stimulatory effect was observed nutrient removal, 46.6% increase in ammonium 44.8% phosphate Additionally, antioxidant activities remained stable, except peroxidase activity . confirms efficient responses algal strains, indicating their potential treatment combating

Removal processes and estrogenic activity of bisphenol—A and triclosan using microalgae

Algal Research, Journal Year: 2024, Volume and Issue: 82, P. 103670 - 103670

Published: Aug. 1, 2024

This study aimed to evaluate the effect of microalgal photoautotrophic treatment on estrogenic activity (EA) and removal process two emerging contaminants (ECs), bisphenol-A (BPA) triclosan (TCS), in synthetic wastewater (SWW). The concentration used for BPA (17 mg/L) TCS (325 μg/L) is median effective (EC50). Two conditions were evaluated, using a microalgae inoculum ≈300 ≈500 mg TSS/L (Total Suspended Solids per liter). For BPA, biodegradation was found be contributing highest percentage removal, reaching >40 % both initial (≈300 TSS/L). TCS, photodegradation, with >28 (sum direct indirect removal). However, it observed that TSS ≈ 500 mg/L TSS, sorption (adsorption absorption) increased by ≈17 respect determined 300 mg/L. Microalgae treatment, TSS/L, resulted reduction EA (by 33 %); but 1.13-fold increase BPA. No at TSS/L. Both treatments >95 ≈86 TCS. removals quantified as 3.8 14.4 %, respectively. an ECs (1.79-fold 1.23-fold TCS). Indirect photodegradation 26.2 14.1 Additionally, showed 2.4-fold whilst 17.99 decrease In conclusion, no linear correlation between EC removals. high efficiencies well decreased

Unveiling the Impact of Thiophanate-Methyl on Arthrospira platensis: Growth, Photosynthetic Pigments, Biomolecules, and Detoxification Enzyme Activities

Frontiers in Bioscience-Landmark, Journal Year: 2023, Volume and Issue: 28(10)

Published: Oct. 25, 2023

Background: The intensive and injudicious use of pesticides in agriculture has emerged as a major concern due to its detrimental impact on aquatic ecosystems. However, the specific broad-spectrum fungicides, such Thiophanate-methyl (TM), cyanobacteria remains subject ongoing research debate. Methods: In order fill this knowledge gap, present study aimed comprehensively investigate toxicological effects TM (10–30 µg/L) growth, photosynthetic pigments, oxidative stress, biochemical composition non-nitrogen-fixing cyanobacterium Arthrospira platensis. Results: Our findings unequivocally demonstrated that exposure significantly inhibited growth A. Moreover, decrease chlorophyll content indicated pronounced negative system platensis caused by exposure. Notably, induced stress platensis, substantiated significant increase lipid peroxidation (MDA) within culture. Furthermore, intracellular generation hydrogen peroxide (H2O2) exhibited positive correlation with higher dosages, while levels vital antioxidant enzymes, catalase (CAT) ascorbate peroxidase (APX), discernible decrease. This suggests compromises defense mechanisms Additionally, was found enhance activity plethora enzymes involved detoxification pesticides, including (POD) glutathione-S-transferase (GST), thereby indicating robust response Interestingly, resulted general suppression biocomponent production, total proteins carbohydrates, which diminishing trend increasing concentration. Conversely, witnessed increase, possibly an adaptive TM-induced stress. Conclusions: These contribute deeper understanding ecological implications pesticide usage emphasize urgent need for adoption sustainable environmentally-friendly agricultural practices safeguard
