A Preliminary Study on Antimicrobial Efficacy of Galactolipid Derivatives and Their Anomeric Mixtures

The in vitro antimicrobial efficacy of α or β O galactolipids and their anomeric mixtures with saturated carbon chains of different length was assessed by Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Results reveal that the anomeric mixture of two O galactolipids with a 12C lipid end inhibit Bacillus subtilis at a low concentration. The minimal inhibitory concentration of this mixture is determined to be 0.06 mmol/L.
