Expression of a recombinant protein by an acetic acid bacterial host.

We evaluated the suitability of Komagataeibacter europaeus, a vinegar production organism adept at synthetic media growth, as a host for heterologous gene expression. Cryptic plasmids (pGE1 and pGE2 derivatives) from K. europaeus strain KGMA0119 were employed as vectors for heterologous gene expression.
