Water phase only DT50 days. In polymerase chain reaction the following programme was used for the amplification of 16S rDNA: Published online Jun The colony was creamish white in color with rough surface. Primary screening Detection of plant growth promoting traits of the isolates All the isolates were screened for brvis expression of plant growth promoting attributes. Working on the same bacterium, Vivas et al.

Brevibacillus brevis

Colour change of the filter paper from deep yellow to orange and finally to dark brown show positive results of HCN production. Several studies recently demonstrated that the combined use of PGPR as a biofertilizers and reduced amounts of chemical fertilizers applied could sustain soil fertility and crop yield Bhardwaj et al.

It was also observed by other researchers that PGPR increases root and shoot hypocotyl lengths. It displayed its nitrogenase activity in terms of ARA. The present study reports the isolation and identification of multi-trait Brevibacillus sp.

Partial purification and characterization of 1-aminocyclopropanecarboxylate deaminase from the plant growth-promoting rhizobacterium Pseudomonas putida GR 12—2. Brevibacillus brevis is considered PGPR and is widespread in the soil and sediment, brevvibacillus it has been widely used in agriculture and environmental remediation because of its multiple potential functions.

Increased growth and yields of many crops like maize, wheat and sweet potato Calvo et al. A review on plant growth promoting rhizobacteria acting as bioinoculants and their biological approach towards the production of sustainable agriculture.

Melting point o Brevibacilus. The seeds of the control treatments were soaked in sterile water.

Its ability to exhibit various PGP traits at higher temperature shows that the isolate may prove effective as an inoculant. Phenotypic microarray analysis of the strain The isolate was analyzed phenotypically by using Biolog system.


Differential response of potato toward inoculation with taxonomically diverse plant growth promoting rhizobacteria. A chromosomally encoded two-component sensory transduction system is required for virulence of Agrobacterium tumefaciens. Retrieved from ” https: Molecular mass g mol Secondary screening of the bacterial isolates To evaluate the potential for plant growth promotion of the screened isolate, germination and seedling vigor tests were performed with cotton Gossypium hirusutm seedlings.

DT50 lab at 20 o C. Today the researchers are being able to use PGPR successfully for the field experiments as they have been potentially recognized for stimulating and increasing plant growth and crop yield.
