Comparison of nucleic acid content in populations of free-living and symbiotic Rhizobium meliloti by flow microfluorometry

A S Paau et al. J Bacteriol. 1977 Feb.

Abstract

Populations of symbiotic Rhizobium meliloti extracted from alfalfa nodules were shown by flow microfluorometry to contain a significant number of bacteroids with higher nucleic acid content than the free-living rhizobia. Bacteroids with lower nucleic acid content than the free-living bacteria were not detected in significant quantities in these populations. These results indicate that the incapability of bacteroids to reestablish growth in nutrient media may not be caused by a decrease in nucleic acid content of the symbiotic rhizobia.
