Plant growth-promoting rhizobacteria (PGPR) are bacteria capable of promoting plant growth by colonizing the plant root. For a long period PGPR were mainly used for assisting plants to uptake nutrients from the environment or preventing plant diseases. Phytoremediation is a new and promising approach to remove contaminants in the environment. But using plants alone for remediation confronts man...

The effect of plant growth-promoting bacteria inoculation on plant growth and the sugar content in Agave americana was assessed. The bacterial strains ACO-34A, ACO-40, and ACO-140, isolated from the A. americana rhizosphere, were selected for this study to evaluate their phenotypic and genotypic characteristics. The three bacterial strains were evaluated via plant inoculation assays, and Azospi...

the effects of plant growth promoting rhizobacteria (pgpr) on growth and physiological characteristics of seedlings corylus avellana were determined in a forest nursery. for this purpose, in a completely randomized design (crd) and four replicates, three putative bacteria, including pseudomonas putida, bacillus subtilis and enterobacter cloacae, as alone and mixed, were examined. the greatest h...

Bacillus pumilus strain WP8 is an efficient plant growth-promoting rhizobacterium. Here, we present the complete genome of WP8 and its genes involved in plant growth promotion and biocontrol.

The base temperature for germination of corn is approximately 10°C, which results in slow germination and emergence of corn crops sown into cool soils. The effects of plant-growth-promoting rhizobacteria (PGPR) and kinetin on grain and sweet corn emergence, plant growth and yield were studied under short season conditions in 1996 and 1997. Two PGPR strains (Serratia proteamaculans 1-102 and Ser...

The role of the interactions between endophytes and alien plants has been unclear yet in plant invasion. We used a completely germ-free culture system to quantify the plant growth-promoting (PGP) effects of endophytic bacteria Bacillus sp. on aseptic seedlings of Wedelia trilobata and of its native clonal congener W. chinensis. The endophytic bacteria did not affect the growth of W. chinensis, ...

Biostimulants are substances and/or microorganisms that applied to plants or the rhizosphere in order enhance natural process improving absorption of nutrients and quality crops as well tolerance abiotic stresses. A new biostimulant was developed from sewage sludge through its fermentation with Bacillus licheniformis a plant growth-promoting bacteria (PGPB). The fermented product includes three...
