Abstract

The present invention relates to glucose- and sophorose-lipids of the formula I ##STR1## in which R.sup.4 is --OH or a group of the formula II, ##STR2## n is an integer from 2 to 26, R.sup.1 and R.sup.2 are, independently of one another, H or ##STR3## R.sup.3 is H or --OH in the case where R.sup.4 is --OH, and is H or --OH or a group of the formula III, ##STR4## in the case where R.sup.4 is a group of the formula II, to a process for obtaining them by fermentation, and to their use as surfactants.
