Abstract
A psychrotrophic bacterial strain resistant to 300 mg l-1 of Cr6+ was isolated from metal contaminated soil samples from a site situated in the Indian Himalayan Region. Based on 16 S rRNA analysis the isolate showed maximum similarity to Rhodococcus erythropolis. Rhodococcus erythropolis MTCC 7905 reduced substantial amounts of Cr6+ to Cr3+ at 10°C and showed plant growth promotion. The isolate offer promise as inoculant to promote plant growth of pea (Pisum sativum) in the presence of toxic Cr6+ concentration. To the best of our knowledge this is the first report on a psychrotrophic strain belonging to species R. erythropolis and its functional characterization to reduce Cr6+ and promote plant growth at low temperature.
