Clément 4 Environmental uses of plant growth - promoting bacteria
نویسندگان
چکیده
Plant growth-promoting bacteria (PGPB) are commonly used to improve crop yields. In addition to their agricultural usefulness, there are potential benefits in environmental applications. For example, species of Azospirillum can increase bioremediation of wastewater by microalgae by increasing algal proliferation and metabolism. Additionally, these genera and several other bacterial species may prevent soil erosion in arid zones by improving growth of desert plants, which in turn leads to reduced dust pollution. Other PGPB promote plants that extract hazardous materials from soil.

Plant growth promoting bacteria effects on growth, photosynthetic pigments and root nutrients uptake of Avena sativa L. under drought stress
Drought stress is one of the most important factors affecting plant growth. Plant growth under drought stress may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria. This research was conducted as a factorial experiment in a completely randomized design. The first factor included the bio-fertilizer (A. vinelandii (A)), P. agglomerans+ P. ...
متن کاملInvestigating the effects of plant growth promoting bacteria and Glomus Mosseae on cadmium phytoremediation by Eucalyptus camaldulensis L.
This research aims to study the effect of Mycorrizal fungus and Plant-Growth-Promoting Bacteria (PGPB) on Cadmium (Cd) uptake by one-year-old Eucalyptus Camaldulensis seedlings. The treatments have involved three levels of heavy metal (0, 30, and 60 mg/kg) for Cd, and three bacterial levels (no bacteria (B0), Bacillus (Ba105), and Pseudomonas (Ps36, Ps448)), inoculated with mycorrhizal fungus G...
متن کاملThe effect of plant growth promoting potentials of rhizosphere bacteria isolated from several halophytic species on vegetative growth and ionic content of wheat
Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from th...
