Abstract
A new mechanism having as an origin the space-time noncommutativity has been shown to generate anisotropy and axial-like interaction giving rise to a leptonic asymmetry for fermionic particles propagating in a curved noncommutative universe. As a by-product, for ultra-relativistic particles like neutrinos, an analytical expression of this asymmetry is derived explicitly. Constraints and bounds from the cosmological parameters are also discussed.
