Resumen
Sixteen strains belonging to three families of the Rhizobiales order (Bradyrhizobiaceae, Phyllobacteriaceae and Rhizobiaceae) were evaluated according their specific growth rates (μ) and the activity of intracellular α-esterase and β-esterase isoenzymes. The average esterase activity of 48 isoenzymes assayed belonging to five strains with low (μ max=0.08-0.12h -1), four medium (μ max=0.13-0.22h -1) and seven high (μ max=0.24-0.28h -1) growth rate values were 22.1±4.3; 8.7±2.2 and 3.9±1.7Ug -1 respectively. An inversely proportional relationship between the activity of the whole pattern of esterases and μ max was found. Our results illustrate a feature of intracellular esterases, ascribable in a variety of cellular functions, which might be related to characteristics μ max of legume infecting bacteria.
