whats so special about a bacteria that eats citrates?


Probably not a lot, unless that particular genus has not been able to do so in the past.

possibly your next question would be "how do we know that genus has not done so before?"

I think the answer to that would have to be that we don't, which is one of the reasons for studies like this.

BTW, "bacteria" is plural.

There never was nothing.
