“…Similar to our findings of multiple plant growth promoting traits in metal resistant PGPR have been reported by some other workers Srivastava et al, 2013), while such findings on metal mobilizing rhizosphere isolates are less commonly explored.…”

“…It has been previously reported by several authors that the inoculation of plants with PGPR, could improve the plant survival in metal polluted soils due to the microbial activity/action in the rhizosphere soils (Prapagdee et al, 2013;Srivastava et al, 2013). In particular, the efficiency of heavy metal extraction by hyperaccumulators can be enhanced by inoculating metal mobilizing PGPR.…”

“…The strain RC6b increased the root length, shoots length, fresh weight and dry weight by 176%, 27%, 27% and 22%, respectively, compared to non-inoculated plants. The increase in plant growth caused by P. myrsinacearum RC6b in metal contaminated soils may be attributed to its ability to produce IAA, ACC deaminase, siderophores and solubilize P (Prapagdee et al, 2013;Srivastava et al, 2013). It has been reported that PGPR (e.g., Bacillus weihenstephanensis, Pseudomonas chlororaphis, Microbacterium lactium, Microbacterium sp., Micrococcus sp., and Klebsiella sp.)…”

h i g h l i g h t sIsolated Phyllobacterium myrsinacearum RC6b effectively mobilized metals in soils. RC6b inoculation enhanced growth and Cd and Zn uptake of Sedum plumbizincicola. Possible mechanisms are plant beneficial activities and soil metal mobilization. RC6b is a good candidate for microbially assisted phytoremediation. a r t i c l e i n f o t r a c tThe aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mobilizing high concentrations of Cd, Zn and Pb in soils. P. myrsinacearum RC6b exhibited a high degree of resistance to Cd (350 mg L À1 ), Zn (1000 mg L À1 ) and Pb (1200 mg L À1 ). Furthermore, P. myrsinacearum RC6b showed multiple plant growth beneficial features including the production of 1-aminocyclopropane-1-carboxylic acid deaminase, indole-3-acetic acid, siderophore and solubilization of insoluble phosphate. Inoculation of P. myrsinacearum RC6b significantly increased S. plumbizincicola growth and organ metal concentrations except Pb, which concentration was lower in root and stem of inoculated plants. The results suggest that the metal mobilizing P. myrsinacearum RC6b could be used as an effective inoculant for the improvement of phytoremediation in multi-metal polluted soils.

“…As it was recently established 99% of all soil bacteria function in close association with soil solids (Costerton et al, 1985;Nannipieri et al, 2017). Bacteria interaction with solid materials of different nature is often followed by the increase of their physiological activity , thus influencing the production of plant hormones (Davies, 2004;Srivastava et al, 2012;Yavorska et al, 2006). Nevertheless, the bacteria interaction with disperse materials and its impact on the synthesis of biologically active substances is still lacks the detailed explanations.…”

Azotobacter vinelandii IMV B-7076 was shown to be capable of biosynthesis and accumulation of various biologically active substances, including high amounts of 3-indoleacetic acid (IAA) in free and bound forms, in the cultural medium. Cultivation of these bacteria with vermiculite particles had increased accumulation of abscisic acid (ABA) in 2.3 times compared to the control. Addition of silica dioxide nanoparticles to the nutrient medium had resulted in higher cytokinin content. Thus, the detected amount of zeatin was 2.4 times higher; zeatin-riboside – higher in 3.6 times; while the content of zeatin-glucoside had a slight increase by 3%. High amounts of cytokinins, 3-indoleacetic and abscisic acids were also detected in the cultural medium of Bacillus subtilis IMV B-7023. Bacteria cultivation in the presence of vermiculite particles in nutrient medium had stimulated an increase of isopentyl adenine content in 4.0 times compared to control. Substantial (in 4.5 times) increase of 3-indoleacetic acid synthesis compared to control was detected. Addition of nanoparticles to the nutrient medium of Bacillus subtilis IMV B-7023 had also promoted synthesis of the abscisic acid in 1.7 times compared to control.
