Cultivable bacteria obtained from a 2,4-DNT contaminated shooting range were compared them to those obtained from a nearby non-contaminated site and investigated for their capacity to metabolize Eco-carbon sources, total cfu-counts on non selective media and their diversity. 2,4-DNT clearly had a negative impact. New 2,4-DNT tolerant strains were identified by selective enrichments which were further characterized by auxanography for 2,4-DNT use, resistance to drought stress, cold, nutrient-starvation and PGP-features. Some of these strains were studied for their capacity for chemotaxis, transformation of 2,4-DNT and their ability to reduce phytotoxicity and improve growth of Arabidopsis plants exposed to this contaminant.
