FIELD: biotechnology, microbiology.
SUBSTANCE: invention proposes the recombinant strain B. anthrax STIΔTPA-1 (pUB110PA-1) that produces the anthrax microorganism protective antigen. The strain is obtained by transformation of the strain B. anthrax STIΔT with hybrid plasmid pUB110PA-1 DNA and deposited in GK of pathogenic microorganisms "Mikrob" at number KM-96. The strain is characterized by stability of hybrid replicon and high level of production of the protective antigen representing the main component of chemical anthrax vaccines, and safety in using.
EFFECT: valuable biological properties of strain.
