Rhizobacteria isolated from wild dipterocarp saplings in Central Kalimantan, Indonesia, were subjected to Salkowski's reagent test, which is often used in detecting indolic substances. Among 69 isolates grown in a low-nitrogen medium supplemented with L-tryptophan (TRP), culture fluids of 29 strains were positive to the test, in which 17 bacteria turned red and other 10 pink. All the red type r...

Root formation and root architecture of olive microshoots, inoculated or not with Pseudomonas fluorescent P19 or P21, were evaluated by measuring of length and the numbers of adventitious and lateral roots. Three-four nodal in vitro shoots were treated with different population densities (0, 105, 108 CFUml-1) of rhizobacteria. The density of 108 CFUmgl-1 induced almost two times increase in num...

indole acetic acid is an important hormone that improved the growth of different plant organs such as the root under normal and stress conditions. as various studies have shown, most of rhizobacteria produce indole acetic acid and thereby contribute to the growth of plants. in this study, different rhizobacteria were isolated from different regions of iran for the assessment of their ability to...

Halotolerant bacteria having 1-aminocyclopropane-1-carboxylate (ACC)-deaminase activity were isolated from wheat rhizosphere and further screened for their plant growth promoting potentials in planta by using wheat as test crop under salinity stress. ACC-deaminase activity ranged from 85 to 399 nmol α-ketobutyrate mg hr of these rhizobacteria. In absence of L-tryptophan, out of 25 rhizobacteria...

Plant growth-promoting rhizobacteria (PGPR) have proved to be an effective solution for enhancing growth of various plant species. Five different bacterial isolates extracted from rhizosphere soil were extensively studied the production indole acetic acid (IAA) and among those Bacillus safensis YKS2 strain was found produce substantial quantities IAA. B. characterized submitted National Centre ...

Azospirillium species are widely used as Biofertilizer to increase crop yield and free-living nitrogen-fixing bacteria, one of the best-studied plant growth-promoting Rhizobacteria. It is commonly found along with roots many different species. The present study included isolation from soils in Rhizospheric regions. 50 isolates were isolated fields districts Saurashtra region Gujarat against NFB...
