This chapter deals with two types of biosurfactants that are not in the spotlight of general research: glycoglycerolipids and oligosaccharide lipids. The main focus is on glycolglycerolipids from marine bacteria like Microbacterium spec. DSM 12583, Micrococcus luteus (Hel 12/2) and Bacillus pumilus strain AAS3 and on oligosaccharide lipids from Tsukamurella spec. DSM 44370 and Nocardia corynebacteroides SM1. General and special structures, microbial producers, production conditions and chemo-enzymatic modifications as well as properties are outlined.
