Perchlorate Reducing Bacterias Having Ecological and Mars Terraforming Significances

Utsav Sunilkumar* and Sanjay Lal

Perchlorate is a tireless contaminant of concern that has introduced various issues to the environment, private segment, government organisation and health of individuals. Moreover, the presence of different sodium and magnesium perchlorates in martian regolith is the most common life inhibiting agent on the red planet. In order to remove the life inhibiting chemical, using microbial methods over chemical and physical is much preferred due to economic and environmental reasons. As an outcome, isolated perchlorate reducing strain of Azospirillum sp. was showing perchlorate reduction in separate mediums with 10 mm of ammonium perchlorate, sodium perchlorate and magnesium perchlorate respectively. In addition to that, isolated Pseudomonas sp. was capable of reducing ammonium perchlorate up to 5 mM and sodium perchlorate up to 1 mM. Among these, Azospirillum sp. may reduce different metallic perchlorate into simpler compounds like oxygen and chloride ion on Mars, irrespective of other physical factors. Moreover, both species can definitely be used for the bioremediation purpose at the perchlorate contaminated sites on earth.
