Quantizability conjecture for Lie bialgebroids

Let $E\to X$ be a Lie algebroid, and suppose its dual bundle $E^*\to X$ is also a Lie algebroid such that the differential $d_{E^*}$ on $\Gamma(X,\wedge^*E)$ is a derivation of the super-bracket on $E$. Call $E$ a Lie bialgebroid. It is quantizable if there exists a deformation of its universal enveloping algebra $UE$ whose semi-classical limit is precisely the given Lie bialgebroid structure.

Quantizability conjecture. Any Lie bialgebroid is quantizable.

This asserts the existence of a deformation quantization for every Lie bialgebroid. The supplied text gives no evidence that the assertion has been proved or disproved, so its status remains open.
