Boletim do IEAA, 16).  aBacteria belonging to the genus Beijerinckia (syn. Azotobacter indicum) which have been reported in some Indian. Australiam and Indonesian soils were found in great abundance in the soils occurring in the area of the Centro Nacional de Ensino e Pesquisa Agronomicas in the Itaguai District, Rio de Janeiro State. Brazil. The number of colonies of Beijerinckia in one gram of soil determined in petri dishes with silica gel media varied somewhat between 0 and 401. Among 20 samples of five different soil series only three didn't contain Beijerinckin. The abundance of these bacteria seems to be related with the vegetation and the physical and chemical properties of the soils. The soil pH seems to have no influence on the occurrence of the Beijerinckia because it was found a great number of them bacteria can develops only with (...)  aBeijerinckia  anitrogen  asoil  aBactéria  aFixação de Nitrogênio  aSolo  aFixation1 aCASTRO, A.
