Chemotaxis by Rhizobium meliloti

Summary Chemotaxis by Rhizobium meliloti strain Ve 26 has been studied and conditions required for chemotaxis have been defined, using the Adler capillary assay technique. Several sugars and amino-acids were shown to be attractants with varying effectiveness for this organism: sugars are weak attractants (except gluconate) and amino-acids are good attractants (except unpolar amino-acids).
