  We theoretically investigate the tunneling transport in a repulsively
interacting ultracold Bose-Fermi mixture. A two-terminal model is applied to
such a mixture and the supersymmetric-like tunneling current through the
junction can be induced by the bias of fermion chemical potential between two
reservoirs. The Goldstino, which is the Nambu-Goldstone fermionic mode
associated with the spontaneous sypersymmetry breaking and appears as a gapped
mode in the presence of the explicit supersymmetry breaking in existing
Bose-Fermi mixtures, is found to contribute to the tunneling transport as a
supercharge exchanging process. Our study provides a potential way to detect
the Goldstino transport in cold atom experiments.
