Objective: to study the effect of co-inoculation with
Ensifer meliloti and Halomonas maura of the leguminous
Medicago sativa L., on growth, nutritional and functional
value, grown under salinity conditions.
Methods: plants of M. sativa were grown in a solution
with a mixture of salts (CaSO4, MgCl, NaCl and NaHCO
3) and were co-inoculated with its specific rhizobium
and the halophilic moderated bacterium H. maura. Different
physiologic parameters were determined, as well as,
nitrogen and minerals content. Furthermore, an assay of
in vitro digestibility was carried out.
Results: salinity had a negative effect on the plants;
however, co-inoculation increased yield, nitrogen content,
total minerals, Ca and Mg. Moreover, physiologic parameters
as water potential and leghemoglobin content in
fresh nodules were higher compared to those of plants
inoculated only with E. meliloti. Both, salinity and bacterial
treatment with E. meliloti and H. maura increased
the antioxidant capacity of the legume, in dialyzates and
retentates collected after an in vitro digestibility assay.
Conclusion: co-inoculation of plants with E. meliloti
and H. maura could improve the alfalfa yield under specific
salinity conditions, increasing the nutritional and
functional value of the plants. M. sativa could be considered
in the formulations of nutritional supplements for
the human diet.
