1. A method for producing a recombinant toxin protein in a Pseudomonad host cell, said method comprising:

  • ligating into an expression vector a nucleotide sequence encoding the toxin protein;

    transforming the Pseudomonad host cell with the expression vector; and

    culturing the transformed Pseudomonad host cell in a culture media suitable for the expression of the recombinant toxin protein;

    wherein the recombinant toxin protein is CRM 197, and wherein the recombinant protein is produced at a yield of soluble or active CRM197 protein of about 0.2 grams per liter to about 12 grams per liter.
