Promotion of Growth and Modulation of As- Induced Stress Ethylene in Maize by As- Tolerant ACC Deaminase Producing Bacteria
One of the major pollutants in the environment is arsenic (As). Due to the toxic effects of As to all organisms, its remediation is necessary. Conventional technologies used in the remediation of As contaminated soils are expensive and may even compromise the structure of the soil. An attractive alternative is phytoremediation, which is the use of plants which can take up the contaminant in the...
متن کاملArsenic uptake by arbuscular mycorrhizal maize (Zea mays L.) grown in an arsenic-contaminated soil with added phosphorus.
The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment. Non-mycorrhizal and zero-P addition controls were included. Plant biomass and concentrations and uptake of As, P, and other nutrients, AM colonization, root leng...
متن کاملMeasurement of ACC-Deaminase Production in Halophilic, Alkalophilic and Haloalkalophilic Bacterial Isolates in Soil
Strains with 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity can cause plant growth on stress condition. In the presence of bacteria with the ability of ACC deaminase production in the rhizosphere, it is possible to convert the ethylene precursor (ACC) to α-ketobutyrate and ammonium, reducing the ethylene levels in host plants. In order to measure the power and level of A...
متن کاملEffects of plant arsenic uptake and heavy metals on arsenic distribution in an arsenic-contaminated soil.
This study examined the effects of heavy metals and plant arsenic uptake on soil arsenic distribution. Chemical fractionation of an arsenic-contaminated soil spiked with 50 or 200mg kg(-1) Ni, Zn, Cd or Pb was performed before and after growing the arsenic hyperaccumulator Pteris vittata L for 8weeks using NH(4)Cl (water-soluble plus exchangeable, WE-As), NH(4)F (Al-As), NaOH (Fe-As), and H(2)S...
متن کاملLuteimonas arsenica sp. nov., an arsenic-tolerant bacterium isolated from arsenic-contaminated soil.
A Gram-stain-negative, rod-shaped bacterium that formed yellow and viscous colonies was isolated from arsenic-contaminated soil of the Jianghan plain, Hubei Province, China, and it was designated 26-35T. This strain was capable of resisting arsenate and arsenite with MICs of 40 and 20 mM, respectively. The 16S rRNA gene of the novel isolate displayed 96.7-94.2 % sequence similarities to those o...
