“…In fact, ACCdeaminase is of great importance when plants face high levels of metals, since the presence of these elements is normally encountered as a stress and plants respond by synthesizing more levels of ethylene, which in turn results in reduced plant growth. Although a number of studies have demonstrated that bacterial inoculation in the rhizosphere of plant species may increase the efficiency of phytoremediation, since plant growth and survival in metal-contaminated soils are improved (He et al 2009;Ma et al 2009a;Madhaiyan et al 2007;Vivas et al 2006) to the best of our knowledge, this is the first research that reports on the potential of R. erythropolis (B1) to increase plant growth in Zn-and Cdcontaminated soils.…”

“…The results of several studies have demonstrated that plant-associated microorganisms contribute to the uptake of metals by plants and improve plant growth under metal exposure (Andreazza et al 2010;Dell'Amico et al 2008;Ma et al 2009a;Madhaiyan et al 2007;Sheng and Xia 2006). Thus, the interactions between plants and beneficial rhizosphere microorganisms may be a key element of any phytoremediation technology (Andreazza et al 2010;Glick 2010).…”

In this work, we evaluated the ability of rhizobacteria isolated from a metal-contaminated site to produce plant growth-promoting substances, such as indole-3-acetic acid (IAA), ammonia, hydrogen cyanide, siderophores and extracellular enzymes, to solubilize phosphate and for 1-aminocyclopropane-1-carboxylate (ACC)-deaminase activity, while assessing their capacity to enhance Trifolium repens growth. The rhizobacteria that better performed were used as bioinoculants for plants grown in zinc-and cadmium-spiked soils. Rhizobacteria were inoculated onto white clover seedlings growing in 250 and 500 mg kg -1 of zinc and in 10 and 30 mg kg -1 of cadmium-spiked soils and plant traits determined. The available and exchangeable rhizosphere metal concentrations were analyzed. Twenty rhizobacteria stimulated white clover growth under axenic conditions. Overall, strains Rhodococcus erythropolis EC 34, Achromobacter sp. 1AP2 and Microbacterium sp. 3ZP2 increased clover biomass in the absence and in presence of metals; however, in soils with 250 mg kg -1 of zinc, bacterial inoculation did not enhance plant biomass. Biomass enhancement may be related to the multiple bacterial promoting traits, especially the production of high levels of IAA and siderophores and the activity of ACC-deaminase. To the best of our knowledge, this is the first study reporting the potential of R. erythropolis to increase plant growth in metal-contaminated soils. In general, strains Microbacterium sp. 3ZP2 and Arthrobacter sp. EC 10 enhanced the available and exchangeable metal concentrations in rhizosphere showing their potential to improve phytoremediation efficiency. This work clearly indicates that rhizobacteria are promising for the development of bioinoculants useful for phytoremediation of polluted soils.

“…Furthermore, they tolerate heavy metals and are able to reduce their phytotoxicity and improve plant growth (Idris et al, 2004;Madhaiyan et al, 2007a). The data presented in this paper include the formal taxonomic description of a novel species of the genus Methylobacterium, which was isolated from rice leaf tissues and produces ACCD.…”

A pink-pigmented, aerobic, facultatively methylotrophic bacterial strain, CBMB27 T , isolated from leaf tissues of rice (Oryza sativa L. 'Dong-Jin'), was analysed using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a clade with the species Methylobacterium oryzae, Methylobacterium fujisawaense and Methylobacterium mesophilicum; strain CBMB27 T showed sequence similarities of 98.3, 98.5 and 97.3 %, respectively, to the type strains of these three species. DNA-DNA hybridization experiments revealed low levels (,38 %) of DNA-DNA relatedness between strain CBMB27 T and its closest relatives. The sequence of the 1-aminocyclopropane-1-carboxylate deaminase gene (acdS) in strain CBMB27 T differed from those of close relatives. The major fatty acid of the isolate was C 18 : 1 v7c and the G+C content of the genomic DNA was 66.8 mol%. Based on the results of 16S rRNA gene sequence analysis, DNA-DNA hybridization, and physiological and biochemical characterization, which enabled the isolate to be differentiated from all recognized species of the genus Methylobacterium, it was concluded that strain CBMB27 T represents a novel species in the genus Methylobacterium for which the name Methylobacterium phyllosphaerae sp. nov. is proposed (type strain CBMB27 T 5LMG 24361 T 5KACC 11716 T 5DSM 19779 T ).

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.
