It doesn't outright disqualify them but it sure is a vote of no confidence in a lot of the popular String Theory models.
I'm not so sure this really means anything much. I'm no expert, but my understanding was that the creation of mini-blackholes was always a longshot, predicted by only one fairly left-field formulation of string theory.
AIUI there are basically two broad classes of string theories - there's the "Brane" theories that holds that we only experience 3D+time out of the possible 10D+time because the other six dimensions form a Brane - a large (possibly universe sized) structure where all quantum particles are constrained to a 3 dimensional "surface" and cannot move in any other direction (except for possibly gravitons). Think in terms of a large piece a paper where everything can move freely across its surface but cannot leave it.
Then there's the second class of string theories which says that the other six dimensions exist in the universe we live in but are somehow "wrapped up" into a tiny volume around each quantum particle rather than being "unwrapped" like the three we're familiar with.
Only this second class of string theory predicts the mini-blackholes. Not only that but the blackholes are only predicted if a least one of the six dimensions are "loosely wrapped" to about a millimeter in size. Most physicists AFAIK already considered it far more likely that all the six dimensions are tightly wrapped to somewhere around the Planck length.
