The forms of deposit certificates and survival certificates issued by different international depository authorities vary. For example, China's international depository institution CGMCC will issue a certification document that contains both the preservation certificate and the survival certificate information. In contrast, IPOE-NITE, Japan's international depository institution, will first issue a preservation certificate, and then issue a separate survival certificate after the survival experiment is verified (most international depository institutions in other countries will issue preservation certificates and survival certificates separately) . Domestic depositories recognized by the State Intellectual Property Office: General Microbiology Center CGMCC of the China Council for the Collection of Microbial Cultures in Beijing; China Type Culture Collection Center CCTCC in Wuhan; and the newly added Guangdong Microbial Culture Collection Center GDMCC.
