The establishment of an agriculture culture collection plays an important role to significantly support for biotechnological development. The main activities of agriculture culture collection are preserving, collect, isolate, evaluate, taxonomy, document and research on application ability of microbes. 673 strains from foreign and domestic including bacteria, yeasts and filamentous fungi were collected, isolated and preserved. Slant agar, sterile distilled water, liquid paraffin, freeze-drying, methylcellulose, or liquid nitrogen freezing was used to preserve cultures to maintain the existent capacity and active biology of them. 49 strains have been screened based on biological activity. 88/183 evaluated strains (48,09%) of agriculture culture collection have multi functional biological activity (nitrogen fixing, phosphorous solubilizing, cellulose degradation, plant growth promoting, tolerant to high temperature, anti pathogenic bacteria, fungi and etc). Bergey’s key taxonomy, Kit API 20E, API 20NE, API 50CH, BIOLOG or sequence analysis of 16S rRNA genes was used for microbial taxonomy. Microbes have been researched, evaluated and utilized in agriculture such as micro-biofertilizer or microbial inoculant. 50 strains have been introduced to produce micro-biofertilizer or microbial inoculants.
