Under the influence of ferric (III) citrate an increase in the content of lipid peroxidation products in bacteria Desulfuromonas acetoxidans IMV B-7384 was observed. It indicates the free radical damage mechanism of lipids. Under these conditions, the specific activity of catalase and reduced glutathione content increased on the second day. Further bacterial cultivation under the presence of ferric (III) citrate caused decrease of specific catalase activity and reduced glutathione content. The storage of lipid peroxidation products may be one of the reasons of decreace of specific catalase activity and reduced glutathione content in D. acetoxidans IMV B-7384 under the influence of ferric (III) citrate.


Keywords: lipid peroxidation, catalase, reduced glutathione, Desulfuromonas acetoxidans -7384
