Researchers at Idaho National Laboratory have discovered that microorganisms can break down urea and promote the formation of calcite, trapping radioactive strontium-90. This process could be used to contain contaminant until it decays away, potentially providing a cheaper and safer alternative to surface extraction.
Scientists discovered that microorganisms in basalt rock can reduce toxic hexavalent chromium to less toxic forms, especially in the presence of volatile organic compounds. The researchers found that certain bacteria, such as Arthrobacter oxydans, play a key role in this process.
A Kansas State University food microbiologist has developed a method to kill E. coli bacteria on meat using microwave and acid treatments. The approach involves dipping the meat in an 80 degrees Celsius solution of lactic acid for a few seconds, followed by short pulses of microwave treatment.
A critical chemical reaction previously thought to support microbial life deep below Earth's surface is now considered highly unlikely. Microorganisms are likely living on organic matter associated with rock, not hydrogen, according to researchers.
Researchers at Savannah River Technology Center found metal-munching bacteria thriving in sterile storage pond environments, threatening long-term nuclear fuel rod integrity. This ill-timed discovery comes as a global downturn in nuclear reprocessing leads to extended storage periods.
