at six concentrations (4.6-90.6 mM) of gluconate added to culture medium for Azospirillum brasilense Cd grown in TYG medium, activity of gluconokinase activity is positively affected; gluconokinase activity significantly increases in inoculated mesquite plants incubated for 23 days, inoculation is not enhanced after 15 days of incubation; while increased gluconokinase activity results only in inoculated treatments, older non-inoculated seedlings maintained the same activity as younger seedlings and the sum of activities of the roots and the negative control is still lower than activity in inoculated plants
