Recombinant expression vector for expression of brazzein and mass production method of brazzein using the same

The present invention relates to a recombinant expression vector for brazein expression and a method for mass production of brazein using the same. More specifically, the expression system for braze was constructed in lactose fermented yeast, Kluyveromyces lactis . In particular, the optimum conditions have been established, and mass production is possible since the expression levels of the E. coli and yeast bacteria are significantly superior to those of the existing expression systems.
