We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal. At concentrations associated with Martian surface regolith, vegetative cells of Bacillus subtilis in Martian analogue environments lost viability within minutes. Two other components of the Martian surface, iron oxides and hydrogen peroxide, act in synergy with irradiated perchlorates to cause a 10.8-fold increase in cell death when compared to cells exposed to UV radiation after 60 seconds of exposure.
Did the test you're referring to account for the chemistry that this test here did? Did it account for the light spectrum as seen on Mars' surface?
And that doesnt even cover the lack of a magnetosphere on mars, something which always conveniently seems left out of terraforming discussions.

really mars cant have life because this or that and yet here on earth there is life in boiling water in yellow stone there is life found in 50000 year old ice there is life found around vents in 2 miles of water that are so toxic the life does not even have 02 and using only minerals to survive.
