Researchers from the University of California, Irvine, along with collaborators from U.S. and Japanese institutions, have engineered a synthetic yeast system that converts urine into hydroxyapatite (HAp). “This process achieves two goals at the same time,” said co-author David Kisailus, UC Irvine professor of materials science and engineering. “On the one hand, it helps remove human urine from wastewater streams, mitigating environmental pollution and the buildup of unwanted nutrients; and on the other hand, it produces a material that can be commercially marketed for use in a variety of settings.” Read More
