Rhamnose for Detection and Isolation of Azotobacter vinelandii Lipman

Abstract

DURING investigations on the utilization of pentoses by Azotobacter spp., A. vinelandii proved to be the only species able to utilize rhamnose as sole carbon source. The experiments were carried out with a nitrogen-free nutrient solution containing mineral salts, 0.1 per cent agar and 1.0 per cent rhamnose as source of carbon and energy. The growth was estimated by comparison with check cultures without carbon source, and in a few cases the nitrogen fixation was determined by Kjeldahl analysis.
