Réponses des diatomées fixées aux pollutions organiques et métalliques dans les hydrosystèmes Nhue-Tolich (Hanoi, Vietnam), et Lot-Riou Mort (France) by Thi Thuy Duong( Book )

Les diatomées périphytiques constituent un modèle biologique parfaitement adapté à l'éude de la qualité des eaux. Dans ce travail, leur structure est étudiée sur des substrats artificiels immergés, par l'analyse de critères généraux (biomasse, densités, diversité...) et spécifiques (abondance relative, indices diatomiques) pour deux types de pollution : pollution organique dans l'hydrosystème Nhue-Tolich (Vietnam), et pollution métallique dans l'hydrosystème Lot-Riou Mort (France). Les résultats montrent que la pollution organique se manifeste par un changement de structure des communautés et une inhibition de leur croissance. Les assemblages diatomiques des sites fortement pollués présentent des espèces tolérantes à la pollution organique comme Nitzschia umbonata, Eolimna minima. Les formes résistantes à la pollution organique comme Gomphonema parvulum, Navicula veneta sont observées dans les sites modérément pollués, et la majorité des espèces sensible (Achnanthidium minutissimum) ainsi que les taxa halophiles (Bacillaria paxillifer) sont trouvés dans le site comparativement non pollué. Par ailleurs, les communautés de diatomées ont répondu au niveau métallique élevé par la présence en grandes proportions d'espèces adhérentes, de petite taille, et résistantes aux métaux comme Eolimna minima et d'espèces présentant des malformations. De fortes corrélations ont également été observées entre l'accumulation du métal dans le biofilm et la présence marquée de certaines espèces de diatomées. Les diatomées apparaissent comme un modèle fiable, qui montre, à travers la structuration de ses communautés, de nombreuses modifications témoigant de l'impact des polluants

Inhibition effect of engineered silver nanoparticles to bloom forming cyanobacteria( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: Silver nanoparticle (AgNP) has a wide range antibacterial effect and is extensively used in different aspects of medicine, food storage, household products, disinfectants, biomonitoring and environmental remediation etc. In the present study, we examined the growth inhibition effect of engineered silver nanoparticles against bloom forming cyanobacterial M. aeruginosa strain. AgNPs were synthesized by a chemical reduction method at room temperature and UV-Vis spectroscopy, scanning electron microscopy (SEM), transmission electron microscope (TEM) showed that they presented a maximum absorption at 410 nm and size range between 10 and 18 nm. M. aeruginosa cells exposed during 10 d to AgNPs to a range of concentrations from 0 to 1 mg l −1 . The changes in cell density and morphology were used to measure the responses of the M. aeruginosa to AgNPs. The control and treatment units had a significant difference in terms of cell density and growth inhibition ( p <0.05). Increasing the concentration of AgNPs, a reduction of the cell growths in all treatment was observed. The inhibition efficiency was reached 98.7% at higher concentration of AgNPs nanoparticles. The term half maximal effective concentration (EC50) based on the cell growth measured by absorbance at 680 nm (A680) was 0.0075 mg l −1 . The inhibition efficiency was 98.7% at high concentration of AgNPs (1 mg l −1 ). Image of SEM and TEM reflected a shrunk and damaged cell wall indicating toxicity of silver nanoparticles toward M. aeruginosa
