This means that we need first to decide on common environment that minimal synthetics will live on. Then, with this environment fixed, we could try to isolate minimal set of genes for multiple different organisms that are originally viable in this environment. Such environment should also be 'minimal' - i.e. having lowest number of resources required to construct it and lowest amounts of those resouces.
