Aged Urine is Safer Fertilizer
>In this new study, researchers have shown that the practice of "aging" collected urine in sealed containers over several months effectively deactivates 99% of antibiotic resistant genes that were present in bacteria in the urine.
>"Based on our results, we think that microorganisms in the urine break down the extracellular DNA in the urine very quickly," said Krista Wigginton, U-M associate professor of civil and environmental engineering, and corresponding author on a study published today in Environmental Science and Technology.
>"That means that if bacteria in the collected urine are resistant to antibiotics and the bacteria die, as they do when they are stored in urine, the released DNA won't pose a risk of transferring resistance to bacteria in the environment when the fertilizer is applied."
