They used growth medium supplemented with a mixture of small peptides and amino acids.
They failed to link the light-activated assembly of the microRNA-RNA-peptide nanocomplex from energy-dependent fixation of amino acid substitutions to viral latency.
The energy-dependent fixation of amino acid substitutions links the weekend resurrection of the irreducibly complex bacterial flagellum to all energy-dependent life on Earth via the physiology of reproduction, which biophysically constrains viral latency. The claim that bacteria evolve over the weekend exemplifies human idiocy. The bacteria adapted via the nutrient energy-dependent pheromone-controlled resurrection of their flagellum.
But see the claim of this biologically uninformed atheist for comparison:
Once again, we see that the example of “cars” used repeatedly by Andrew Jones @aj170664, and other biologically uninformed science idiots, also exemplifies human idiocy. See:
Anything on Earth older than the experimental evidence-based claims about the past 5-10,000 years of protection from viral latency, would have required the use of ecologically relevant “magic traits” to create and maintain itself in the context of reduction–oxidation (redox) reactions that destroy it during chemical reactions in which the oxidation states of atoms are changed.

If you do not agree that Andrew Jones @aj170664, and others like him are among the most ignorant of all fools who have ever temporarily inhabited this planet, see his thesis on how abiogenesis led to the evolution of self-replicating ribozymes.

…our simple and adaptable screening approach can be applied for the development of various assay systems aimed at the identification of bioactive small molecules targeting protein–RNA interactions.
The weekend resurrection of the bacterial flagellum occurred in P. fluorescens, an organism that exhibits light-activated microRNA-mediated fluorescence when exposed to UV light.

Another antagonist asked: What is there to go on about?
The unnecessary suffering and premature death caused by virus-driven mutations is something to go on about.
See for example, the works of KB Whaley, one of President Donald Trump’s scientific advisors. When the links from quantum physics to quantum biology and quantum souls are revealed, all hell may break loose in the academic and political swamps that must be drained to limit the death toll attributed the the Harvard Business Plan of obfuscated light-activated microRNA-mediated energy-dependent cause and effect.
