Abstract

Anionic, surface-active trehalose lipids, in which different organic acids are bound to a trehalose molecule by an ester linkage, are prepared by aerobically cultivating trehalose-producing microorganisms, capable of assimilating hydrocarbons, under growth-limiting conditions, but without limiting the oxygen.
