Birds – Acute LD 50 mg kg Role of Brevibacillus brevis in plant growth Brevibacillus brevis is considered PGPR and is widespread in the soil and sediment, and it has been widely used in agriculture and environmental remediation because of its brevibadillus potential functions.

PGPR was isolated from rhizospheric soil of cotton plants. It shows that bervibacillus IAA producing ability of the isolate decreases with the increase in the temperature, similar results were also reported by Sudha et al. Protein measurement with folin-phenol reagent.

Background Agriculture is the major sector for economic development of third world countries. All the isolates were screened for the expression of plant growth promoting attributes. PGPR inhabit plant roots and exert a positive effect ranging from direct influence mechanisms to an indirect effect.

A Gram-positive bacterium that was originally isolated from soil in Scotland, UK. The bacterial isolate was checked for its growth and survival at high temperatures.
