Abstract:

We employ agar dilution method to determine the bacteriostasis activity of a carboxylic ligand and its cerium complexes to Escherichia aureus, Staplylococcus aureus and Bacillus subtilis. We also obtain their minimal inhibitory concentration (MIC). Results show that carboxylic acid and its cerium complexes have stronger bacteriostasis activity the bacteriostasis activity of its cerium complexes is higher than that of the dual ligand and lower than that of the unitary ligand.

Key words: cerium, carboxylic acid complexes, bacteriostasis performance, mininal inhibitory concentration
