It was found to be resistant to high levels of Nickel as well as other toxic metals. Upon ribotyping SM1 was found to be Proteus mirabilis with a Genbank accession number of KT873815. The isolate was seen to accumulate nickel in its cell cytoplasm as found out by TEM, EDXRS and XRD analysis. The isolate further produced Siderophore and Indole Acetic acid (IAA) and showed Plant Growth Promotion chracteristics when tested on Indian mustard (Brassica hirta) leading to significant decrease in the nickel amassing by plants when the mustard seeds were grown in nickel contaminated soil along with the isolate. http://pubs.sciepub.com/aees/10/3/5/aees-10-3-5.pdf nickel resistant MTC Plant Growth Promoting Rhizobacteria (PGPR)
