Abstract

Rhizobium leguminosarum cells were separated into four distinct fractions by using density gradient centrifugation for the separation of the outer and cytoplasmic membranes and lysozyme-EDTA treatment of whole cells for the isolation of the periplasmic and cytoplasmic fractions. These methods allowed the subcellular localization of R. leguminosarum proteins.
