Phosphate-solubilizing bacteria (PSB) increase phosphate bioavailability, thereby reducing the application frequency of chemical fertilizers in the production of Nicotiana tabacum (tobacco). In this study, PSB were isolated from tobacco plants for the fi rst time. These PSB were screened in vitro for their ability to solubilize inorganic P (Pi) when grown in association with tobacco plants. Thirty-six PSB with the ability to solubilize P i were isolated and screened for their indolyl-3-acetic acid and siderophore-producing capabilities. In addition, all 36 PSB strains had a partial fragment of their 16S rRNA gene sequenced. The analysis revealed high sequence identity to 16S rDNA sequences from Bacillus, Arthrobacter, Providencia, Enterobacter, Proteus, Psychrobacter, Serratia, Rhodococcus, Pseudomonas, Ochrobactrum, and Acinetobacter. Of the 36 PSB strains analyzed, three (Psychrobacter alimentarius HB15, Enterobacter ludwigii HB21, and Ochrobactrum haematophilum HB36) were selected for a controlled plant inoculation experiment. Inoculation of tobacco plants with these bacterial strains signifi cantly increased plant dry weight. Additionally, inoculation increased P, K, and N uptake by tobacco seedlings as well as soil P availability. The increases observed with inoculation were even more pronounced when tricalcium phosphate (TCP) was added to the soil. The phosphate-solubilizing activity of these three strains was correlated with the release of gluconic, tartaric, acetic, and citric organic acids. Overall, co-inoculation of PSB and TCP appears to represent a promising option for increasing the yield of tobacco plants. The adoption of this technique could provide a pathway to reducing fertilizer input in agricultural settings.

Interactions between plants and microorganism are complex and can affect the establishment of plant communities and change ecosystem properties. These interactions are of interest for researchers and have many ecological and biotechnological applications. The present study is the first report on the microbial diversity associated with Butia purpurascens Glassman, and the goal was to isolate and identify the genetic diversity of endophytic and rhizospheric growable microorganisms from B. purpurascens using molecular biology techniques. Endophytic and rhizospheric microorganisms were isolated from the roots and rhizospheric soil of the purple yatay palm. DNA was extracted, and the 16S region for bacteria and internal transcribed spacer (ITS) region for fungi were amplified and sequenced. The resulting sequences were compared with known sequences from GenBank by similarity search using BLASTn. The rhizosphere and roots of B. purpurascens harbor a diverse set of microorganism groups. Fourteen (14) genera of endophytic and 12 genera of rhizospheric bacteria were identified that belonged to three phyla (Proteobacteria, Firmicutes and Actinobacteria), and 11 endophytic and six rhizospheric genera of fungi were identified that belonged to the phylum Ascomycota. The most frequent isolated genera were Enterobacter and Pseudomonas for endophytic bacteria, Gibberella and Codinaeopsis for endophytic fungi, Bacillus and Enterobacter for rhizospheric bacteria, and Ceratocystis for rhizospheric fungi. Differences were observed between the endophytic and rhizospheric microbial communities of B. purpurascens, with some microorganisms only detected in one environment. Further studies with a higher number of individuals are required to confirm these results.

“…Los resultados de la actividad in vitro de solubilización de fosfato, mostró 3 bacterias endófitas con esta actividad (M1H1: M1H4; M1H3), al igual que 6 bacterias rizosféricas (M6-2; M6-6; M3R; M13R; M1-8R; M6-5), (Figura 6). El fósforo aunque es uno de los principales macronutrientes esencial para cualquier organismo vivo, se encuentra poco disponible en especial para las plantas, debido a que la mayor parte del fósforo se encuentra en el suelo en forma mineral, lo cual lo hace insoluble y no disponible; solo las formas solubles de este, lo convierten en disponibles tanto para plantas como para microorganismos (BEHERA et al, 2014). Una de las características de las bacterias endófitas es la habilidad de incrementar la movilización del fosfato, por el desarrollo de mecanismos que permiten captar las formas de fosfato insoluble, liberarlo y haciéndolo disponible para la planta (RYAN et al, 2008).…”

The present study had as objective to evaluate in vitro the resistance of endophytic bacteria and rizospheric bacteria to different concentrations of Cadmium.This bacteria were isolated fron different tissues of commercial rice varieties and from bacteria isolated from the rhizosphere in rice plantations of the Nechí (Antioquía) and Achí (Bolivar). Plant growth promotion was evaluated in vitro by nitrogen fixation, phosphate solubilization and siderophores production of endophytic bacteria. Of each tissue isolated from rice plants was carried out isolation in culture medium for endophytic bacteria, and the soil samples were serially diluted in peptone water. Each sample was determined the population density by counting in CFU / g of tissue and morphotypes were separated by shape, color, size and appearance in culture media. Significant differences were observed for density population of bacteria with respect to tissue, with higher values in root (4x10 11 g/root), followed of the stem (3x10 10 g/etem), leaf (5x10 9 g/ leaf), flag leaf (3x10 9 g/ flag leaf) and with less density in panicle (4x10 8 g/panicle). The results of the identification with kit API were confirmed the presence of endophytic bacteria Burkholderia cepaceae and rizospheric bacteria Pseudomona fluorescens With the ability to tolerate different concentrations of Cd, fix nitrogen, solubilize phosphates and produce siderophores. Keywords:Rizospheric bacteria; rizosphere; tolerance; Cd ResumenEl presente estudio tuvo como objetivo evaluar in vitro la resistencia de bacterias endófitas y rizosféricas a diferentes concentraciones de Cadmio (Cd). Se evaluó in vitro la promoción de crecimiento vegetal mediante la fijación de nitrógeno, solubilización de fosfato y producción de sideróforos de bacterias endófitas aisladas de diferentes tejidos de variedades de arroz comerciales y de bacterias aisladas de la rizósfera en las plantaciones de arroz de los corregimientos de Nechí (Antioquía) y Achí (Bolívar). Se colectaron muestras de raíz, tallos y hojas de plantas de arroz y de muestras de suelo rizosférico. A cada muestra se les determinó la densidad poblacional por medio de conteo en UFC/ g de tejido y se separaron morfotipos por forma, color, tamaño y apariencia en medios de cultivos. Se observaron diferencias significativas para densidad poblacional de bacterias con respecto a tejido, con mayores valores en raíz (4x10 11 g/raíz), seguida de tallo (3x10 10 g/tallo), hoja (5x10 9 g/hoja), hoja bandera (3x10 9 g/hoja bandera) y menor densidad en panícula (4x10 8 g/panícula). Los resultados de la identificación con kit API20E confirmaron la presencia de la bacteria endófita Burkholderia cepaceae y la bacteria rizosférica Pseudomona fluorescens con capacidad de tolerar diferentes concentraciones de Cd, fijar nitrógeno, solubilizar fosfatos y producir sideróforos.
