“…Likewise, certain bacteria such as Pseudomonas aeruginosa were shown to possess a high capacity to solubilize poorly soluble Zn compounds in aqueous media or soil (Fasim et al 2002). The Zn solubilization activities of PGPR strains can be attributed to secretion of organic acid anions and protons, leading to reduced pH and enhanced solubility of Zn compounds (Azarmi et al, 2016). The bacterial ability to utilize rubber as a food source (along with Zn solubilization capacity) is of paramount signi cance, which has been reported for Pseudomonas aeruginosa AL98 strain that was capable of degrading natural rubber (Chengalroyen and Dabbs 2013).…”

“…In both soil and liquid culture experiments, the pH decreased in the presence of bacteria relative to the control treatment. By secreting organic acid anions, protons and CO 2 , bacteria can decrease the pH and, as a result, enhance the solubility of water-insoluble Zn compounds (Azarmi et al, 2016).…”

“…The dry weights of shoot and root tissues were recorded after oven-drying at 65 °C for 48 h. The shoot and root samples were ground using a stainless-steel grinder. The ground root/shoot samples were dissolved in 2 N hydrochloric (HCl) acid after dry ashing at 500 °C, and the concentration of Zn and Fe in the extract was measured using an atomic absorption spectrophotometer (GBC Avanta ver.1.33, GBC Scienti c, Dandenong, Australia) (Azarmi et al 2016).…”

Car tires contain considerable amounts of zinc (Zn), hence, tire waste materials can be a potential source of Zn for plants. The present study was conducted to investigate the potential of Zn-solubilizing Pseudomonas strains to release Zn from tire waste powder (TWP) in a liquid medium and soil. A pot experiment was also conducted to investigate the effects of TWP and Pseudomonas strains on growth and Zn nutrition of maize. Fourteen bacterial strains were grown in liquid Pikovskayas (PVK) medium supplemented with TWP, and ten superior Pseudomonas strains with high Zn solubilization activities were selected for the subsequent Zn kinetics study. In the liquid PVK medium supplemented with TWP, the concentration of Zn was higher in all inoculated treatments compared to the non-inoculated control in a time-dependent manner. Likewise, in the TWP-treated soil, the concentrations of DTPA-extractable Zn were significantly higher in inoculated treatments than those in the control treatment in all incubation times. Individual application of Pseudomonas strains or TWP treatments significantly increased the shoot biomass of maize plants. Furthermore, the combined application of Pseudomonas strains and TWP led to higher shoot Zn concentration of plants as compared to the individual applications, reflecting enhanced Zn availability in TWP-treated soil upon bacterial inoculation. These findings indicate that co-application of effective Pseudomonas strains (with high Zn solubilization activity) with TWP in soils can lead to higher Zn bioavailability for plants, i.e. indicating the potential of TWP as a slow-release Zn fertilizer for crops.

“…It was reported that shoot dry weight of the pistachio seedling treated with the plant growth promoting rhizobacteria (PGPR) significantly increased comparison with the control. Production of organic acids, enzyme ACC-deaminase, IAA, siderophore, HCN as well as increasing the bioavailability of nutrients such as P, Zn and K are reasons for the improvement of the pistachio seedling growth inoculated with fluorescent pseudomonads rhizobacteria (Azarmi et al, 2016).…”

Summary: Root morphology can be affected by many factors such as microorganisms. To determine the effect of effective microorganisms (EM) on the root morphology of sweet corn under salt stress, a factorial experiment was carried out in a randomized complete block design with three replications in Islamic Azad University of Sabzevar in 2013. Examined factors included application method of EM (soil application, foliar application and soil+foliar application) and intensity of salinity (0, 25, 50, 75 mM). Commercial solution of EM was applied at30liters per hectare for soil application and foliar application during five-leaf stage. The highest root dry weight, root density and membrane stability were observed in soil application while the highest root volume, root length, root and shoot dry weight occurred when soil and foliar application were performed together. With increasing intensity of salinity, all traits decreased and the highest traits were observed in the control treatment. Soil application of EM in comparison with other methods alleviates effects of salinity under saline conditions.
