“…The reason might be that some plants involve the use of plant growth-promoting bacteria or mycorrhizal fungi to lessen the deleterious effects of heavy metals. Achromobacter piechaudii ARV8 Tomatoes and peppers Resistant to water and salt stress Mayak et al, 2004a;2004b Rhizospheric microorganism The rhizobacteria of metal accumulating and hyperaccumulating plants and their role in the tolerance to and uptake of heavy metals by the plants have been studied. Research has also shown that many rhizobacteria are tolerant to heavy metals and play important roles in mobilization or immobilization of heavy metals (Gadd, 1990).…”

Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Rhizosphere, as an important interface of soil and plant, plays a significant role in phytoremediation of contaminated soil by heavy metals, in which, microbial populations are known to affect heavy metal mobility and availability to the plant through release of chelating agents, acidification, phosphate solubilization and redox changes, and therefore, have potential to enhance phytoremediation processes. Phytoremediation strategies with appropriate heavy metal-adapted rhizobacteria have received more and more attention. This article paper reviews some recent advances in effect and significance of rhizobacteria in phytoremediation of heavy metal contaminated soils. There is also a need to improve our understanding of the mechanisms involved in the transfer and mobilization of heavy metals by rhizobacteria and to conduct research on the selection of microbial isolates from rhizosphere of plants growing on heavy metal contaminated soils for specific restoration programmes.

Two hundred and thirty-two bacterial strains were isolated from the rhizospheric soil of Populus euphratica which is the dominant tree living in extreme arid regions in northwest China. Some strains with plant growth-promoting bacteria related metabolic characteristics were able to promote drought resistance in plants after inoculation. Ten strains with the greatest effects increased the dry weight of wheat shoots from 0.5 to 34.4 %, and the surface area of the root systems from 12.56 to 212.17 % compared to the control after drought treatment whereas no obvious promoting effect was observed in normal water conditions. These 10 strains were identified to be of the genera Pseudomonas, Bacillus, Stenotrophomonas and Serratia by 16S rRNA (rrs) gene sequence alignment. Among these strains, Serratia sp. 1-9 and Pseudomonas sp. 5-23 were the two most effective strains. Both of them produced auxin and the production increased significantly when cultured under simulated drought conditions which are inferred to be the most plausible mechanism for their plant growth-promoting effect under drought stress.

“…It is also suggested that root-colonising bacteria which produce phytohormones, when bound to the seed coat of a developing seedling, may act as a mechanism for plant growth stimulation and these organisms can prevent the deleterious effects of stresses from the environment (Lindberg et al 1985, Frankenberger andArshad 1995). The beneficial attributes of these organisms also include improved nutrient recycling in the rhizosphere microcosm and root colonization are some of the challenges under stress (Mayak et al 2004, Paul and Nair 2008, Berg 2009, Lugtenberg and Kamilova 2009. P. extremorientalis TSAU20 and P. chlororaphis TSAU13 showed their capacity to increase the growth of various crops under saline conditions Kucharova 2009, Egamberdieva et al 2010).…”

The abilities of Pseudomonas extremorientalis TSAU20 and P. chlororaphis TSAU13 to colonise and survive in the rhizosphere of common bean under saline conditions were studied. Four salinity levels (5.0, 7.5, 10.0, and 12.5 dS/m) were maintained in the gnotobiotic system using NaCl salt. Results showed that with increasing salt content root-tip colonization of both bacterial strains was reduced. Both bacterial treatments used in the study intcreased root and/or shoot length compared to non-treated plants at each NaCl concentration tested, whereas shoot growth was not stimulated at high saline condition (12.5 dS/m). In conclusion, the results of this study indicated that P. extremorientalis TSAU20 and P. chlororaphis TSAU 13 have the ability to survive in ecologically stressed conditions, such as saline and nitrogen deficient soils, and may positively effect on plant growth of bean. High saslinity inhibited their colonisation in the rhizosphere of bean and thus their stimulatory effect on plants was also reduced.
