| dc.description | In this document, reference is made to the Azospirillum bacteria as a biofertilizer for the growth of rice (Oryza sativa L.). The objective was to evaluate the value of the Azospirillum bacteria (Azospirillum spp.) for rice biofertilization. According to the findings, the genus Azospirillum is a class of Gram-negative bacteria that fix nitrogen, produce auxins, gibberellins and cytokinins, as well as siderophores and bacteriocins. Azospirillum bacteria induce plant growth, including the synthesis of hormones such as auxins (indole acetic acid), cytokinins, and abscisic acid. Therefore, it is necessary to choose a carrier that provides optimal conditions for bacteria to survive during storage and is also economical in creating liquid and solid media for mass production of these bacteria. Also included are the solubilization of phosphates, the fixation of atmospheric nitrogen and the synthesis of substances that inhibit the growth of phytopathogenic microorganisms, such as siderophores, chitinases and antibiotics. In relation to biofertilizers, a commercial movement has been created, and the production and marketing of these products aims to strengthen a sustainable production system and the ecological balance of the soil, totally or partially reducing the use of synthetic fertilizers. | es_ES |

| dc.description.abstract | En este documento se hace referencia a la bacteria Azospirillum como biofertilizante para el crecimiento del arroz (Oryza sativa L.). El objetivo fue evaluar el valor de la bacteria Azospirillum (Azospirillum spp.) para la biofertilización del arroz. Según los hallazgos, el género Azospirillum es una clase de bacterias Gram negativas que fijan nitrógeno, producen auxinas, giberelinas y citoquininas, así como sideróforos y bacteriocinas. Las bacterias Azospirillum inducen el crecimiento de las plantas, incluida la síntesis de hormonas como auxinas (ácido indol acético), citoquininas y ácido abscísico. Por lo tanto, es necesario elegir un portador que proporcione condiciones óptimas para que las bacterias sobrevivan durante el almacenamiento y que además sea económico a la hora de crear medios líquidos y sólidos para la producción masiva de estas bacterias. También se incluyen la solubilización de fosfatos, la fijación de nitrógeno atmosférico y la síntesis de sustancias que inhiben el crecimiento de microorganismos fitopatógenos, como sideróforos, quitinasas y antibióticos. En relación a los biofertilizantes, se ha creado un movimiento comercial, y la producción y comercialización de estos productos tienen como objetivo fortalecer un sistema de producción sustentable y el equilibrio ecológico del suelo, reduciendo total o parcialmente el uso de fertilizantes sintéticos. | es_ES |
