Published: Jan. 16, 2025

The combination of silver nanoparticles (AgNPs) and ciprofloxacin (CIP) can be considered an alternative to combat multidrug-resistant microbial infections. However, knowledge about their combined toxicity is scarce after being released in aquatic environment. present study evaluated the individual AgNPs CIP on unicellular green microalga Chlorella vulgaris, evaluating cellular responses conducting metabolomic analysis. median effective concentrations at 96 h (EC50-96h) for AgNPs, CIP, mixture were 132 µg L-1, 7000 452 respectively. exhibited a synergistic effect with AgNPs. toxic ranking C. vulgaris was > + CIP. growth rate most evident parameter toxicity. Cell diameter significantly increased (p < 0.001) hours highest tested mixture, increases 24%, 41%, 19%, respectively, compared control. Photosynthetic pigment analyses revealed that upregulated chlorophyll, carotenoids, pheophytin. exposure caused SOS response involving protein carbohydrate tolerate antibiotic stress. Exposure catalase glutathione S-transferase activity, but decreased activity. malondialdehyde content exposed cells due fatty acid peroxidation. These pollutants potential risks interfering survival metabolism. Our findings highlight possible hazards co-pollutants environmentally relevant quantities, providing insights into ecotoxicity

Re-vitalizing wastewater: Nutrient recovery and carbon capture through microbe-algae synergy using omics-biology

Environmental Research, Journal Year: 2024, Volume and Issue: 259, P. 119439 - 119439

Published: June 18, 2024

Increasing amounts of wastewater is the most pervasive and challenging environmental problem globally. Conventional treatment methods are costly entail huge energy carbon consumption greenhouse gas emissions. Owing to their unique ability capturing resource recovery, microalgae-microbiome based a potential approach widely used for carbon-neutral treatment. Microalgae-bacteria synergy (i.e., functionally beneficial microbial synthetic communities) performs better enhances carbon-sequestration nutrient recovery from plants. This review presents comprehensive information regarding as sustainable agent discusses synergistic approaches effective removal. Moreover, this discusses, role omics-biology Insilco in unravelling understanding algae-microbe synergism response toward Finally, it various microbiome engineering developing microalgae-bacteria partners sequestration wastewater, summarizes future research perspectives on bioremediation.

Phycospheric Bacteria Alleviate the Stress of Erythromycin on Auxenochlorella pyrenoidosa by Regulating Nitrogen Metabolism

Plants, Journal Year: 2025, Volume and Issue: 14(1), P. 121 - 121

Published: Jan. 3, 2025

Macrolide pollution has attracted a great deal of attention because its ecotoxic effects on microalgae, but the role phycospheric bacteria under antibiotic stress remains unclear. This study explored toxic erythromycin (ERY) growth and nitrogen metabolism Auxenochlorella pyrenoidosa; then, it analyzed predicted composition ecological function microalgae ERY stress. We found that 0.1, 1.0, 10 mg/L inhibited chlorophyll gradually showed enhanced abilities over course 21 days. As exposure time progressed, nitrate reductase activities increased, remained significantly lower than control group at d. NO3− concentrations in all treatment groups decreased were consistent with growth. NO2− three those during changed community diversity bacteria. The relative abundance bacteria, such as unclassified-f-Rhizobiaceae, Mesorhizobium, Sphingopyxis, Aquimonas, Blastomonas, varied to different degrees. Metabolic functions, ABC transporters, microbial diverse environments, biosynthesis amino acids, upregulated treatments higher (1.0 mg/L). Higher denitrification, nitrous oxide nitrite respiration. findings this suggest alleviate restore by regulating system.
