Phytohormones Producing Acinetobacter bouvetii P1 Mitigates Chromate Stress in Sunflower by Provoking Host Antioxidant Response.

ABSTRACT: Different physical and chemical techniques are used for the decontamination of Cr⁺⁶ contaminated sites. The techniques are expensive, laborious, and time-consuming. However, remediation of Cr⁺⁶ by microbes is viable, efficient, and cost-effective. In this context, plant growth-promoting rhizobacteria Acinetobacter bouvetii P1 isolated from the industrial zone was tested for its role in relieving Cr⁺⁶ induced oxidative stress in sunflower. At the elevated Cr⁺⁶ levels and in the absence of P1, the growth of the sunflower plants was inhibited. In contrast, the selected strain P1 restored the sunflower growth under Cr⁺⁶ through plant growth-promoting interactions. Specifically, P1 biotransformed the Cr⁺⁶ into a stable and
