Arsenic (As) in the environment is an increasing problem all over the world that limits crop yield, and therefore, remediation strategies like inoculation with plant growth promoting rhizobacteria (PGPR) are necessary. The objective of the current study was to assess PGPR ability to reduce AsIII toxicity in grapevine (Vitis vinifera L. cv. Malbec). Two-year old grape plant-sprouts grown in 10 L pots were inoculated weekly with Bacillus licheniformis, Micrococcus luteus, Pseudomonas fluorescens, a consortium of the three strains, or water (control).
