Plant growth-promoting bacteria that decrease heavy metal toxicity in plants

Abstract: Kluyvera ascorbata SUD165 and a siderophore-overproducing mutant of this bacterium, K. ascorbata SUD165/26, were used to inoculate tomato, canola, and Indian mustard seeds which were then grown in soil for 25-42 days in the presence of either nickel, lead, or zinc. The parameters that were monitored included plant wet and dry weight, protein and chlorophyll content in the plant leaves, and concentration of heavy metal in the plant roots and shoots. As indicated by a decrease in the measured values of these par… Show more

“…Siderophore producing bacteria were well known to increase the resistance of plant to pathogens [8] by providing the plants with additional iron. As for the abiotic stress, the role of siderophore production was demonstrated by the siderophore-over-producing mutant Kluyvera ascorbata SUD165/26 which was more efficient than wild type bacterium in protecting the plants against heavy metal stress [26].…”

“…Just like the character of PGPR in the remediation of organic compounds, they can also prompt plant growth by the synthesis of ACC deaminase (Belimov et al, 2005;Burd et al, 1998;Reed et al, 2005;Safronova et al, 2006). PGPR with ACC deaminase were isolated from rhizosphere of various plants (Belimov et al, 2001).…”

“…PGPR with ACC deaminase were isolated from rhizosphere of various plants (Belimov et al, 2001). What's more, some rhizobacteria can promote plant growth by the synthesis of other compounds, such as siderophores, indole-3-acetic acid (IAA) and antibiotics with heavy metal contaminants, which is different from organic pollutants (Burd et al, 2000;Glick, 2001;Pattern and Glick, 1996) or though stimulation of certain metabolic pathways such as nitrogen fixation and the uptake of nitrogen, phosphorus, S, Mg, Ca and other nutrients (Bashan and Levanony, 1990;Belimov and Dietz, 2000;Okon and Labandera-Gonzalez, (2003) 1994). Leong (1986) reported that heavy metals in soils could stimulate the production of siderophores.…”

“…Addition of this bacterial strain signifi cantly decreased the toxicity of the added nickel [39]. Addition of a bacterial strain P. maltophila was shown to reduce the mobile and toxic Cr(VI) to immobile and nontoxic Cr(III) thereby minimizing the mobility of metal ions [20].…”
