Brevibacillus expression system is an effective bacterial expression system for secretory proteins. The host bacterium, Brevibacillus choshinensis, a gram-positive bacterium, has strong capacity to secrete a large amount of proteins (∼30g/L), which mostly consist of cell wall protein. A host-vector system that utilizes such high expression capacity has been constructed for the production of secretory proteins and tested for various heterologous proteins, including cytokines, enzymes, antigens, and adjuvants.
