For example, it is a pathogenic bacterium and has endotoxins; it secretes protein into the periplasm and often into inclusion bodies. Bacillus subtilis is an attractive host for the production of heterologous secretory proteins. Many genes has succeed expressed in Bacillus subtilis, and the plasmid vectors for Bacillus subtilis are now taken from other genus bacterium, such as Staphylococcus aureus or lactococcus lactis and so on. As it is clear to known that these plasmids are far from optimal for Bacillus subtilis, because of low efficiencies of cloning and high levels of replicating instability.
