Phosphate-solubilizing bacteria (PSB) have the ability to solubilize insoluble phosphorus (P) and release soluble P. Extensive research has been performed with respect to PSB isolation from the rhizospheres of various plants, but little is known about the prevalence of PSB in the grapevine rhizosphere. In this study, we aimed to isolate and identify PSB from the grapevine rhizosphere in five vineyards of Northwest China, to characterize their plant-growth-promoting (PGP) traits, evaluate the effect of stress on their phosphate-solubilizing activity (PSA), and test their ability to stimulate the growth of Vitis vinifera L. cv. Cabernet Sauvignon. From the vineyard soils, 66 PSB isolates were screened, and 10 strains with high PSA were identified by 16S rRNA sequencing. Sequence analysis revealed that these 10 strains belonged to 4 genera and 5 species: Bacillus aryabhattai, B. megaterium, Klebsiella variicola, Stenotrophomonas rhizophila, and Enterobacter aerogenes. The selected PSB strains JY17 (B. aryabhattai) and JY22 (B. aryabhattai) were positive for multiple PGP traits, including nitrogen fixation and production of indole acetic acid (IAA), siderophores, 1-aminocyclopropane-1-carboxylate (ACC) deaminase, chitinase, and protease. JY17 and JY22 showed strong PSA under stress conditions of high pH, high salt, and high temperature. Therefore, these two isolates can be used as biofertilizers in saline-alkaline soils. The inoculation with PSB significantly facilitated the growth of V. vinifera cv. Cabernet Sauvignon under greenhouse conditions. Use of these PSB as biofertilizers will increase the available P content in soils, minimize P-fertilizer application, reduce environmental pollution, and promote sustainable agriculture.Additional key words: promote plant growth; inorganic phosphate; stress conditions; saline-alkaline soil; Vitis vinifera L. cv.

“…Las PGPR cumplen una función importante en los suelos al transformar algunos nutrientes, presentes frecuentemente en formas menos disponibles, en formas biológicamente viables (Acevedo, Galindo-Castaneda, Prada, Navia, y Romero, 2014). Las PGPR pueden ser separadas en dos grupos: las PGPR extracelulares, las cuales habitan en la rizósfera, sobre el rizoplano o en los espacios intercelulares de la corteza de la raíz, y las PGPR intracelulares que viven dentro de las células de la raíz en estructuras nodulares especializadas (Kumar et al, 2015).…”

Una opción empresarial para cultivadores de frutas y hortalizas U n i v e r s i d a d S i m ó n B o l í v a r RESUMEN En Colombia, el Instituto Colombiano Agropecuario (ICA) es la entidad encargada de regular la producción y comercialización de bioinsumos de uso agrícola. El presente estudio tuvo como objetivo describir los inoculantes biológicos producidos en el país que actúan como biofertilizantes. Para esto se consultó el listado de productos bioinsumos del ICA y se analizó a través Microsoft® Excel2010, y el programa SPSS 21.0® las variables, lugar de producción, ingredientes activos, tipo de formulación, actividad biológica y cultivos autorizados. Se encontró que la mayor producción de inoculantes se concentra en el departamento de Cundinamarca; asimismo, los principales microorganismos utilizados para el desarrollo de estos productos correspondieron a los hongos micorrizcos del género Glomus y Acaulospora, así como a las bacterias Azotobacter chroocoocum y Bradyrhizobium japonicum. La mayor parte de los inoculantes ostenta actividades biológicas varias y se presentan bajo formulación de tipo sólida. El arroz constituye el cultivo más frecuente de aplicación de los inoculantes. El trabajo permitió concluir que hay una nula producción de inoculantes biológicos en la mayoría de departamentos que conforman la región Caribe, en los cuales se producen cultivos de gran importancia para la seguridad alimentaria del país.Palabras clave: Biofertilizantes, rizobacterias promotoras de crecimiento vegetal, micorrizas arbusculares, Colombia. ABSTRACTIn Colombia, the Colombian Agricultural Institute (ICA) is the entity in charge of regulating the production and commercialization of bioinoculants for agricultural use. The present study had as objec-tive to describe the biological inoculants produced in the country that act as biofertilizers. For this we consulted the ICA bioinoculants products list and were analyzed through Microsoft® Excel 2010 and the program SPSS 21.0® the variables production location, active ingredients, type of formulation, biological activity and authorized crops. It was found that the highest production of inoculants is concentrated in the Cundinamarca department; furthermore, the main microorganisms used for these products development were the mycorrhizal fungi belonging to the genus Glomus and Acaulospora, also the bacteria Azotobacter chroocoocum and Bradyrhizobium japonicum. Most inoculants have various biological activities and are presented under a solid type formulation. Rice is the most frequent crop in which inoculants are applied. The work allowed concluding that there is not biological inoculants production in most of Caribbean Region departments in which great importance crops for the country food security are produced.
