“…Some ACC deaminase-producing plant growth-promoting bacteria promote plant growth by lowering the level of ethylene in plants growing in the presence of heavy metals (Glick and Penrose, 2004;Glick et al, 2007). Although the endophytic bacterial communities of heavy metal-hyperaccumulators have been analyzed (Idris et al, 2004;Chen et al, 2012;Wei et al, 2014), the characteristics of Mn-resistant endophytic bacteria of Mn-hyperaccumulator, P. americana, have not been reported. Furthermore, endophytic bacteria may be of particular interest as they have the advantage of being relatively protected from the competitive, high-stress environment of the soil (Sturz et al, 2000).…”

“…Phytolacca americana is a Mn-hyperaccumulator widely distributed on Mn mining wastelands and Mn-contaminated soils (Dou et al, 2009;Wei et al, 2014). In recent years, endophytic bacteria and their interaction with hyperaccumulating plants have attracted the attention of investigators (Barzanti et al, 2007;Sheng et al, 2008;Chen et al, 2012). Endophytic bacteria live inside plant tissues without causing damage to their hosts and play an important role in agriculture by conferring advantages to the plant (Hallmann et al, 1997;Mengoni et al, 2003).…”

“…A previous study has reported that HM ions are immobilized in the soil by using various additives and plants is one of the better approaches to investigate soil HM contamination456. The accumulation of highly toxic HM in soil affects the microbial diversity, the soil nutrient supply and food production789. Additionally, the bioavailability of each HM also affects the soil microbial diversity10.…”

In this study, we investigated the influence of heavy metals (HM) on total soil bacterial population and its diversity pattern from 10 km distance of a Zinc smelter in Feng County, Qinling Mountain, China. We characterized and identified the bacterial community in a HM polluted soil using 16S rDNA technology. Out results indicated that the maximum soil HM concentration and the minimum bacterial population were observed in S2 soil, whereas bacterial diversity raised with the sampling distance increased. The bacterial communities were dominated by the phyla Proteobacteria, Acidobacteria and Actinobacteria in cornfield soils, except Fimicutes phylum which dominated in hilly area soil. The soil CEC, humic acid (HA)/fulvic acid (FA) and microbial OTUs increased with the sampling distance increased. Shewanella, Halomonas and Escherichia genera were highly tolerant to HM stress in both cultivated and non-cultivated soil. Finally, we found a consistent correlation of bacterial diversity with total HM and SOM along the sampling distance surrounding the zinc smelter, which could provide a new insight into the bacterial community-assisted and phytoremediation of HM contaminated soils.

“…Burkholderia,Alcaligenes, Agrococcus, Polaromonas, Stenotrophomonas, Serratia, Microbacterium and Caulobacter were root endophytes exclusively. Serratia species were also found as root endophytes in the Cd-hyperacumulator Solanum nigrum byChen et al (2012).…”

The interaction between plant growth-promoting bacteria (PGPB) and plants can enhance biomass production and metal tolerance of the host plants. This work aimed at isolating and characterizing the cultivable bacterial community associated with Brassica napus growing on a Zn-contaminated site, for selecting cultivable PGPB that might enhance biomass production and metal tolerance of energy crops. The effects of some of these bacterial strains on root growth of B. napus exposed to increasing Zn and Cd concentrations were assessed. A total of 426 morphologically different bacterial strains were isolated from the soil, the rhizosphere, and the roots and stems of B. napus. The diversity of the isolated bacterial populations was similar in rhizosphere and roots, but lower in soil and stem compartments. Burkoholderia, Alcaligenes, Agrococcus, Polaromonas, Stenotrophomonas, Serratia, Microbacterium, and Caulobacter were found as root endophytes exclusively. The inoculation of seeds with Pseudomonas sp. strains 228 and 256, and Serratia sp. strain 246 facilitated the root development of B. napus at 1,000 µM Zn. Arthrobacter sp. strain 222, Serratia sp. strain 246, and Pseudomonas sp. 228 and 262 increased the root length at 300 µM Cd.
