“…Large production of EPS was only observed in 17 isolates (20% of all the M. paraibana isolates and 8% of the M. tenuiflora isolates). Rapid growth is a common characteristic of native isolates from the Brazilian semiarid region obtained from nodules of several species (Teixeira et al, 2010;Medeiros et al, 2009). Usually, isolates of rapid development do not form dry colonies (Teixeira et al, 2010) but this was the case in 16% of the isolates from M. tenuiflora and 6% of the isolates from M. paraibana (Figure 2).…”

“…are scarce (Chen et al, 2005;Bontemps et al, 2010;Reis Jr et al, 2010;Teixeira et al, 2010), it is difficult to evaluate the frequency of these phenotypes. Medeiros et al (2009) reported that punctiform colonies are commonly formed by isolates from nodules of Vigna unguiculata cultivated in soils from Caatinga areas. Cowpea associates with a large diversity of rhizobia and due to this characteristic it is frequently used as a trap culture (Melloni et al, 2006;Medeiros et al, 2009).…”

“…For completing the development, part of the nitrogen required by the peanut is obtained by symbiosis with bacteria rhizobia, the process called biological nitrogen fixation (BNF). These bacteria induce the plant nodulation and, when selected, may increase symbiotic efficiency by progressively increasing grain yield and nodulation [3].…”

“…However, the importance of peanut inoculation in tropical regions may be adopted under conditions such as low population of native rhizobia, high temperatures, low soil moisture, or in those areas where the peanut or other legume was not grown. Due to the importance [3], of the BNF process for the sustainability of agricultural production, the objective of this present study had to evaluate the effect of the inoculation of native rhizobia strains on peanut cultivated in Cerrado's Oxisol.…”
