        Agricultural Culture Collection of China (ACCC) established in 1979, base on the culture preservation lab of the institute of soils and fertilizers of Chinese Academy of Agriculture Science (CAAS). ACCC is one of the native nonprofit microbial resource centers of China whose mission focuses on the acquisition, identification, preservation, and distribution of agricultural microorganisms. ACCC also provides service for society, such as inspection for microbial inoculate products, consultancy, microbial resources information services, and training courses. ACCC has the website (http://www.accc.org.cn) and strain information search system from 2001.
      The repository portion of the facility occupies 400 square meters and contains 5 freezers rooms to store biomaterials, including vapor-phase liquid nitrogen freezers, mechanical freezers and cold rooms. The repository space is complemented by 800 square meters of four professional laboratories for bacteria, actinomeycetes, rhizobium, anaerobic microorganism, filamentous fungi, yeast and macro-filamentous fungi.  ACCC holds more than 16,000 strains belongs to 737 genus 2476 species.
     ACCC used 2-3 preservation methods for every strain. Sub-culturing method used for mush room and micro-filamentous fungi preservation. Freeze-drying method used for bacteria yeast and the micro-filamentous fungi produced spore from 1985. Cryopreservation preservation in liquid nitrogen used for mush room and plant pathogen preservation from 2001. Most bacteria and actinomycetes have preserved at -80℃. ACCC has trained specialized person for the work of preservation and basic identification. And also have a scientist team for evaluation and agricultural application of microbial resources, such as Biocontrol, Bioferlilizer, Biodegradation, and Mush room, and so on.
