This study was carried out using indoor controlled experiments to study the arsenic uptake, biotransformation, and release behaviors of freshwater algae under growth stress. Three freshwater algae, Microcystis aeruginosa, Anabaena flosaquae, and Chlorella sp.,Two types of inhibitors, Cu2+ and isothiazolinone, inhibit the growth of the algae. The algae were cultivated to a logarithmic stage in growth media containing0.1 mg/L P; then,0.8 mg/LAs in the form of arsenate (iAsV) was added,while both inhibitors were simultaneously added at dosages of 0.1 and 0.3 mg/LAfter 2 days of exposure, the average growth rate was measured to represent the growth rates of the algae cells; the extra- and intracellular monomethyl arsenic, and di-Me arsenic, were also measured,Without inhibitors,M.aeruginosa significantly higher than that of the other two algae.However, when Cu2+ was added as an external inhibitor, the order of the average growth rate for the three algae became partially reversed.The great reduction in M. aeruginosa growth rate was accompanied by increases in extracellular iAsV and iAsIII and intracellular iAs concentrations The biol.productivity of As by the three algae followed the order of M.aeruginosa, Chlorella sp.,and A.flosaquae,generally consistent with the As transformation and release in conditions with and without inhibitors, suggesting that the As behavior in the algae that was related to growth stress largely differed among algae species. In the experiment, the researchers used many compounds, for example, Isothiazol-3(2H)-one (cas: 1003-07-2Quality Control of Isothiazol-3(2H)-one).
Isothiazol-3(2H)-one (cas: 1003-07-2) belongs to isothiazole derivatives. Similar to other five-membered heterocycles, isothiazoles react with a wide range of electrophilic and nucleophilic reagents to form diverse products. It has been found that isothiazole-based compounds show synergistic effects when used with other biocidal compounds.Quality Control of Isothiazol-3(2H)-one
