摘要：Algae are the most predominant members of photosynthetic eukaryotic forms, which form a major componentof global aquatic ecosystem in India. Tannery industries around Erode and Tirupur in Tamil Nadu face theproblem of algal growth in reverse osmosis unit due to the presence of chemicals such as ammonium,ferrous salts, sulphate and nitrates of other metals. The refuse after tannery treatment causes eutrophicationof aquatic ecosystems, which is a major problem in this surrounding area. Selenium nanoparticles can havesignificant adverse effects on growth and morphology of the filamentous green algae in a dose-dependentmanner. In the present study, our objective is to expose organic nanoparticles with various concentrations tothe algal cells and inhibit the same. The bacterial strain Lactobacillus sp., found in milk, was used for thesynthesis of nanoparticles and in the pH range of 7-8 and temperature ranging from 30°C-35°C couldeffectively inhibit the algal cells. Characterization studies were performed including UV-Vis Spectrophotometerand SEM micrograph to confirm the presence of nanoparticles. The production of dimethyl selenide by algalcells becomes toxic to the algae themselves and thus causing death. The technology can be readilyimplemented in industries.
