Article title at the moment is: Microbe That Could Turn Martian Dust into Oxygen
Neither of those are particularly misleading, but requires you to read it carefully I suppose, otherwise it can misleading I suppose. I guess "Martian Dust" is the most misleading part of the quote, as the soil isn't actually Martian of origin, but actually "materials that are similar to Martian soil".
Both titles are very misleading, because neither "oxygen is produced from Martian soil" nor "Martian dust is turned into oxygen".
As I have said, the oxygen comes only from water, which is missing on Mars, unlike the abundant Martian soil or Martian dust.
So the "microbe" does not solve the problem of oxygen production, which is obtaining water. With water, making oxygen by electrolysis is trivial and a problem solved long ago.
The cyanobacterium can make various useful organic substances, like proteins and vitamins. The fact that it also makes some oxygen is a minor additional advantage.
Even if such cyanobacteria will be grown on Mars, most of the oxygen will be made by electrolysis anyway, because the efficiency from solar light to free oxygen is much better and the photovoltaic cells continue to function in a much wider range of temperatures.
