Researchers in Germany and Switzerland used next generation sequencing to study an active aquaponics system. They sampled a biofilm from the side of the tank, the fish excrement, the plant roots, and the inside of the tank filter, called a biofilter.
The latest cutting-edge water filtration technique comes from a biochemistry process that predates even dinosaurs. It involves harnessing aquaporins, a protein in cell membranes which are present in all living things.
Jacob Haqq-Misra, Ravi Kopparapu, and Eric Wolf attempt to address this question in a recent paper titled “Why do we find ourselves around a yellow star instead of a red star?” and published in International Journal of Astrobiology.
