Summary: The objective of this work was to evaluate the effect of different carbon souces on the exopolysaccharides composition produced by Rhizobium tropici SEMIA 4077 and SEMIA 4080, and the effect of these strains inoculation on the nodulation in common bean. The carbon sources used interfered on the concentrations of the galactose and glucose of exopolysaccharides, being higher in SEMIA 4080 strain when cultivated in sucrose medium. Even though SEMIA 4080 strain produced a large quantity of exopolysaccharides in culture, there was no difference between strains regarding the number of nodules, independently of the carbon source used for inoculum preparation. However, in the parameter dry weight of nodules there was significant difference between the strains, independently of the carbon sources used for inoculum preparation.

As fontes de carbono utilizadas interferiram nas concentrações de galactose e glicose dos exopolissacarídeos, que foram maior na SEMIA 4080 em meio com sacarose. Embora a SEMIA 4080 tenha liberado grande quantidade de exopolissacarídeos na cultura, não houve diferença entre as estirpes quanto ao número de nódulos do feijoeiro, independentemente da fonte de carbono utilizada no preparo do inóculo. No parâmetro matéria seca de nódulos, houve diferença entre as estirpes, independentemente da fonte de carbono utilizada no preparo do inóculo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileira2007-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://apct.sede.embrapa.br/pab/article/view/772510.1590/S1678-3921.pab2007.v42.7725Pesquisa Agropecuaria Brasileira; v.42, n.10, out. 2007; 1503-1506Pesquisa Agropecuária Brasileira; v.42, n.10, out. 2007; 1503-15061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://apct.sede.embrapa.br/pab/article/view/7725/4644Castellane, Tereza Cristina LuqueLemos, Eliana Gertrudes de Macedoinfo:eu-repo/semantics/openAccess2014-10-13T18:57:07Zoai:ojs.pkp.sfu.ca:article/7725Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T18:57:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
