  • Abstract:
  • Three bacterial colonies were isolated from tannery effluent collected from Negalkeni Village, Pallavaram, Chennai. All isolates were tested for their ability to grow in Cr(VI)-spiked nutrient media at increasing concentrations (50, 100, and 150 mg/L). Of the three, only one strain was able to grow in Cr(VI)-supplemented medium for 5 days. This strain was identified as a Pseudomonas species based on primary and secondary biochemical tests. Additionally plant-growth-promoting (PGP) activities, including phosphate solubilization, siderophore production, and HCN production, were also tested and found to be positive for this isolate.
