Here is an alleged testable predictionSuperstring theory involves a single unifying superstring current for bosons and fermions that in the low-energy limit generalizes the Klein-Gordon (not the Dirac) current. By adopting a relativistic-covariant probabilistic interpretation of the current, the low-energy limit implies electron interference patterns that, under certain conditions, differ from those predicted by the Dirac current.

Do you understand where his claim "(ii) that it cannot be derived from low-energy supersymmetric field theory" comes from? I would have said that "bosonic and fermionic particles are different states of the same object" in any supersymmetric theory.
