Report Summarizes Vibrio fischeri Study Findings from Maria Curie-Sklodowska University

June 20, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- Current study results on Proteobacteria have been published. According to news reporting originating from Lublin, Poland, by NewsRx correspondents, research stated, "The aim of the research was the determination of the toxicity of photocatalytically treated water contaminated by different pharmaceuticals: chloramphenicol (CPL), diclofenac (DCF) or metoprolol (MT). Daphtoxkit F-TM with Dapnia magna and Microtox() with Vibrio fischeri were used to evaluate the toxicity of the water before and after treatment. D. magna showed higher sensitivity to the presence of pharmaceuticals than V. fischeri."

Our news editors obtained a quote from the research from Maria Curie-Sklodowska University, "Generally, both tested organisms revealed the greatest sensitivity to the presence of CPL The application of photocatalytic oxidation has resulted in decreased toxicity. It may confirm the reduction of high toxic parent compounds to less toxic metabolites. The toxicity was reduced in the range from 30% to 100% depending on pharmaceutical tested. The highest reduction of toxicity to V fischeri and D. magna was observed to MT and CPL respectively."

According to the news editors, the research concluded: "Depending on bioassay the toxicity decrease as follows: CPL > DCF > MT for D. magna and CPL > MT > DCF for V. fischeri."
