Última Diversity and nitrogen fixation efficiency of rhizobia isolated from nodules of Centrolobium paraense PAB Baraúna,Alexandre Cardoso; Silva,Krisle da; Pereira,Gilmara Maria Duarte; Kaminski,Paulo Emílio; Perin,Liamara; Zilli,Jerri Edson. The objective of this work was to isolate and characterize rhizobia from nodules of Centrolobium paraense and to evaluate their symbiotic efficiency. Soil samples collected from four sites of the Roraima Cerrado, Brazil, were used to cultivate C. paraense in order to obtain nodules. Isolates (178) were obtained from 334 nodules after cultivation on medium 79. Twenty-five isolates belonging to six morphological groups were authenticated using Vigna unguiculata and they were characterized by 16S rRNA. Isolates identified as Bradyrhizobium were further characterized using rpoB gene sequencing. A greenhouse experiment was carried out with C. paraense to test the 18 authenticated isolates. Approximately 90% of the isolates grew slowly in medium 79. The 16S rRNA...
