WASHINGTON - (Left) Wild-type Escherichia coli a non-melanin producing strain and (right) bioengineered E. coli mutant with the Tyr1 gene to produce melanin in liquid media. A melanin biofilm is observable in the mutant strain that is part of a U.S. Naval Research Laboratory (NRL) project called Microbes for Multiple Uses in Space Project (MELSP) in Washington, D.C., October 10, 2023. NRL’s MELSP will use the International Space Station (ISS) to search for production of melanin variants and other useful biomaterials that have applications both on Earth and in space.
