Ralstonia pickettii
（重定向自Pseudomonas pickettii）
Ralstonia pickettii is a Gram-negative rod soil bacterium.
Ralstonia pickettii is a gram-negative, rod shaped beta proteobacteria found in moist environments such as soils, river and lakes. It has also been identified in biofilms in plastic water pipes. It is an oligotrophic organism, making it capable of surviving in areas with a very low concentration of nutrients. Several strains have shown an ability to survive in environments highly contaminated with metals. The ability to persist in these harsh conditions makes R. picketti a unique candidate for bioremediation.
