dc.descriptionPlant growth promoting bacteria (PGPB) are found in the rhizosphere of plants as a heterogeneous group. Among its characteristics are the genetic capacity to produce indole-3-acetic acid from L-tryptophan and the production of organic acids and phosphate solubilizing enzymes. The production of indole-3-acetic acid of each bacteria culture was measured using the Salkowski reagent applying the liquid spectrophotometry technique. On the other hand, to evaluate the potential of organic acid production of phosphorus solubility, the National Botanical Research Institute, Pune (NBRIP) culture medium was used applying the liquid spectrophotometry technique. All evaluated bacteria showed the ability to produce indole-3-acetic acid and organic acids of phosphorus solubility. The strains of Pseudomonas sp. examined in this study were the most efficient in the production of AAI and the strains of Bacillus sp. were the most efficient in the solubility of phosphates.
