Abstract
The effects of an extracellular microbial glycolipid, the interfacial active lactonic sophoroselipid, and of Triton X‐100 on strains of Acinetobacter calcoaceticus are compared. Sophoroselipid diminished growth rates on n‐heptadecane. Both surfactants led to the excretion of enzyme activities into the culture medium. Sophoroselipid increased the release of cytoplasmic malate dehydrogenase whereas in presence of Triton X‐100 the quinoprotein glucose dehydrogenase was also excreted in large amounts.
