Abstract:

Medium-chain fatty acid glycerides have become a new hot spot in the research of antibiotic substitutes. The purpose of this study was to investigate the bacteriostatic effects of lauric acid, glycerol monooctanoate, glycerol monolaurate and glycerol octanoate on Escherichia coli, Staphylococcus aureus, Salmonella enteritidis and Salmonella pullorum. The results showed that four medium-chain fatty acid glycerides had certain inhibitory effects on four kinds of pathogenic bacteria. Among them, the effects of lauric acid, glycerol monolaurate and glycerol monooctanoate on four kinds of pathogenic bacteria increased with time.

Key words: medium chain fatty acids, Escherichia coli, Salmonella enteritidis, Staphylococcus aureus, Salmonella pullorum, bacteriostatic effect
