I want to know the answer to the following question:
What is given to Citrobacter to cause it to absorb uranyl ions?
All the background I'm provided with is that "After one day, one gram of bacteria can encrust themselves with nine grams of uranyl phosphate crystals; this creates the possibility that these organisms could be used in bioremediation to decontaminate uranium-polluted water.". Is that enough to answer the question?
