Radiation-resistant microorganism
View Patent ↗An isolated and purified bacterium is provided which was isolated from a high-level radioactive waste site of mixed waste. The isolate has the ability to degrade a wide variety of organic contaminants while demonstrating high tolerance to ionizing radiation. The organism is uniquely suited to bioremediation of a variety or organic contaminants while in the presence of ionizing radiation.
1. An enrichment culture having all the identifying characteristics of ATCCBAA-149.
2. A mixed culture of microorganisms comprising a plurality of microorganisms ATCC BAA-149 or a mutant thereof, wherein said mixed culture degrades a contaminant selected from the group consisting of aromatic amines, benzene, biphenyl, diphenylamine, organic carbon, phenol, polycyclic aromatics, tetraphenyborate and combinations thereof in the presence of ionizing radiation levels of at least about 10 Gy per hour.
