In a new study published today in Science Advances, researchers present a 3D-printable ink that contains bacteria and they say that depending on what species of bacteria it holds, the ink stands to have a number of useful applications. “Printing using bacteria-containing hydrogels has enormous potential, as there is such a wide range of useful bacteria out there,” Patrick Rühs, an author of the study, said in a statement.
For the past year and a half, citizens of Flint, Michigan have been struggling to get clean, safe water to drink. The city switched its water source from the Detroit water supply to the Flint river, causing a slew of public health problems, including high concentrations of E. coli bacteria and a recent outbreak of Legionnaires’ disease that killed 10.
