Abstract
Glycerol monolaurate is a broadly antimicrobial fatty acid monoester, killing bacteria, fungi, and enveloped viruses. The compound kills stationary-phase cultures of

Glycerol monolaurate alone was bactericidal for all five organisms tested. Glycerol monolaurate alone was effective in killing spores. When solubilized in a nonaqueous gel, the glycerol monolaurate gel was bactericidal for all spores tested. The data suggest that glycerol monolaurate nonaqueous gel could be effective in decontaminating environmental and body surfaces, such as skin.
and
spores are known to be highly resistant to killing, persisting on environmental and human body surfaces for long periods of time. In favorable environments, these spores may germinate and cause human diseases. It is thus important to identify agents that can be used on both environmental and human skin and mucosal surfaces and that are effective in killing spores. We previously showed that the fatty acid monoester glycerol monolaurate (GML) kills stationary-phase cultures of
Since such cultures are likely to contain spores, it is possible that GML and a human-use-approved GML nonaqueous gel would kill

spores. The significance of our studies is that we have identified GML, and, to a greater extent, GML solubilized in a nonaqueous gel, as effective in killing spores from both bacterial genera.
