No, I just doubt that the gained ability to metabolize citrate is going to help the species survive.

If the ability to metabolize citrate is a property that makes a difference to similar species, it actually has been proven by those species that it is an advantage that helps to survive under certain conditions.

And I dont know how they gained the ability. But there really is too much left out of the article to form a healthy hypothesis.

I don't think that 20 years of scientific evaluations, if they are worth the word 'scientific', can be presented in such a small article.

Although, I agree that the article gives not enough information to show why this is a prove of evolution.
