This study characterized bean strains from two contrasting ecosystems in Brazil, the Northeast Region, with a semi-arid climate and neutral soils and the South Region, with a humid subtropical climate and acid soils. Seedlings of the cultivars Negro Argel and Aporé were used to trap 243 rhizobial isolates from 12 out of 14 sites.  aBeans  aNitrogen fixation  aFeijão  aFixação de Nitrogênio  aRizóbio1 aHUNGRIA, M.  tSoil Biology and Biochemistrygv. 36, n. 9, p. 1389-1398, Sept. 2004.
