“…The results coincide with those reported by other authors who demonstrated the positive effect of inoculation of tomato plants with strains of Bacillus (Lagunas et al, 2001;Luna Martinez et al, 2013. ) And other bacterial genera such as Azospirillum (Terry-Alfonso et al, 2005), Pseudomonas (Gravel et al, 2007) and Rhizobium (Santillana et al, 2005). This behavior could be related to the production of metabolites of IAA type by the inoculated strain.…”

“…This behavior could be related to the production of metabolites of IAA type by the inoculated strain. The IAA induces plant growth by increasing cell division and differentiation of tissue, effects that are reflected in a higher content of biomass (Lagunas et al, 2001;Santillana et al, 2005). It has also been argued that the IAA absorbed by the seeds and roots of plants could stimulate the activity of the ACC synthase enzyme, which is involved in the synthesis of ethylene.…”

The capacity to solubilize phosphate and to produce indole compounds Indole Acetic Acid type, was evaluated in 15 strains isolated from castor bean lignocellulosic residues (Ricinus communis). To determine the solubilizing activity of phosphates a qualitative test by using Pikovskaya culture medium was employed and for the evaluation of the production of indole compounds (IAA) a Salkowsky colorimetric analysis technique was applied. Among the microorganisms tested, the Bacillus pumilus GIBI 206 demonstrated capacity to solubilize phosphates and Bacillus subtilis GIBI 200 showed of capacity to solubilize phosphates and to produce Indoleacetic Acid (IAA). To determine the effect of the Bacillus subtilis strain on germination and growth promotion, tomato seeds (Solanum lycopersicum 'Santa Clara') were inoculated; the inoculation of the seeds along with the microorganism revealed statistically significant differences, during the germination stage compared to the control treatment. Nevertheless, it revealed a positive influence on the development of tomato plants, originating a significant increase on the mass and length of its stem and root. The results of this research offer the possibility of using the Bacillus subtilis as a growth promoter in tomato seedlings and in the formulation of bio-products.

“…for the biological inoculant production is an economic and ecological alternative to ensure and recover the productivity of the soils, reducing the indiscriminate use of chemical fertilizers. This rhizobacteria, in addition to fixing nitrogen produce phytohormones, participate in the solubilization of phosphorus and antagonistic reaction, allowing a greater productivity of the host legume plant in any type of soil (Akhtar and Siddiqui, 2009;Santillana et al, 2005;Mourad et al, 2009;Bardin et al, 2004;Puertas et al, 2006;Ahemad andKibret, 2014, Mabrouk et al, 2018).…”

Biological fixation of nitrogen by native isolates of Rhizobium sp. symbionts of Leucaena leucocephala (Lam.) De Wit

Forage legumes such as Leucaena leucocephala, besides being a rich source of protein for animal feed, its inclusion in silvopastoral systems provides fundamental components to improve soil properties. These plants have the ability to establish symbiotic association with the genus Rhizobium sp. and fix biologically atmospheric nitrogen favoring growth and development, being reflected in production increases. The objective of this research was to evaluate the capacity of native isolates of Rhizobium sp. and a commercial strain in biological nitrogen fixation (BNF) in L. leucocephala plants. Two separate bioassays to evaluate the efficiency of the FBN of the native isolates and the commercial strain under greenhouse conditions, followed by a randomized complete block design with 7 x 2 factorial arrangement, seven treatments, two factors: native isolates and commercial strains and bacterial concentrations (106 and 108 cells.ml-1), with three repetitions and five experimental units. The first bioassay was carried out with seeds, determining the percentage of germination, the length and thickness of the stem, number of leaves, dry weight of the aerial part, number of nodule/plant and the percentage of nitrogen accumulated in the area part of the plant. In the second bioassay with 30-day-old seedlings, the same variables of the first bioassay were determined, with the exception of the percentage of germination. In the first bioassay, a greater stimulation was found in the germination of L. leucocephala seeds at a concentration of 108 cells.mL-1. Regarding stem length and thickness, accumulated dry matter, leaf development and nitrogen accumulation, better results were found in the treatments with the native isolates L27, L36 and L38 in a concentration of 106 cells.mL-1 above the commercial strain in concentration of 108 cells.mL-1. The native isolates of Rhizobium sp. exert a positive effect on the FBN and the germination of plants of L. leucocephala, which will allow to conduct future field studies that allow to potentiate the culture of L. leucocephala and silvopastoral systems for bovine feeding.

“…Los biofertilizantes no tienen un efecto contaminante sobre el suelo ya que los microorganismos contenidos en estos se utilizan para aumentar la disponibilidad de algunos nutrientes cómo el P que es de baja disponibilidad (Ohtomo y Saito, 2005), fijar nitrógeno y aumentar la disponibilidad de nitrógeno en hortalizas, como tomate (Santillana et al, 2005) y cebolla (Balemi et al, 2007), y ofrecer a la raíz protección contra patógenos (Morales-Ibarra, 2009).…”

El objetivo de este estudio fue conocer el efecto de Azospirillum sp. y Glomus intraradices en el cultivo de pimiento de color amarillo en condiciones de invernadero. Los tratamientos consistieron en diversas combinaciones que incluían soluciones diluidas de Steiner con 2 concentraciones de bacterias (10 4 y 10 6 UFC ml-1), 2 concentraciones de endomicorrizas (25 y 50 esporas) y 4 tratamientos combinando bacterias y endomicorrizas. Se incluyó un tratamiento testigo con solución completa de Steiner. El diseño experimental fue bloques completamente al azar con 9 tratamientos y 20 repeticiones. Las variables altura de planta, diámetro de tallo, diámetro ecuatorial y polar de fruto, peso de fruto y rendimientos mostraron mejores resultados usando combinación de bacterias y hongos. La calidad nutracéutica (vitamina C, Sólidos Solubles Totales e índice de acidez) se mejoró con la inoculación de 50 esporas y 10 6 UFC ml-1. En carotenoides los mejores resultados se obtuvieron con 10 4 y 10 6 UFC ml-1 combinado con 50 esporas. Los minerales N y P aumentaron con el uso de los inoculantes en una dosis de 10 6 UFC ml-1 combinado con 50 esporas y una solución nutritiva de 50%N-50%P. La concentración de N y P se incrementó en fruto en ambas concentraciones de inóculo de bacteria y esporas de micorrizas.
