HERNANDEZ MENDOZA, José L. et al. The conservation of the agricultural use bacteria Azospirillum Brasilense by microencapsulation. Rev. Bol. Quim [online]. 2018, vol.35, n.4, pp.117-122. ISSN 0250-5460.

ABSTRACT Microencapsulation is performed to protect or provide a cover for substances that are easily alterable, with the objective to mask flavors, store chemicals and transform products of traditional use into smart products, capable of changing under environmental conditions. In this work the process of encapsulation of the bacterium Azospirillum brasilense was evaluated. Different concentrations of sodium alginate and calcium chloride were used to achieve better yields, stability and viability. The best conditions to form a microcapsule were the combination of 2% alginate and 1M calcium chloride. Five years later the encapsulated bacteria underwent reléase, used the LB médium and germinating maize seeds. Bacteria were found viable, suggesting that the encapsulation of bacteria, or other microorganisms that associate with plants, as serving as agricultural inoculants.
