Immobilized Strain Propagation and Release and Its Performance

doi:10.11924/j.issn.1000-6850.casb15100038

Abstract

Abstract: The release of immobilized strains under different soil conditions was different. In the study, the release and degradation characteristic of immobilized Bacillus subtilis under different soil conditions were analyzed, the release condition of immobilized strain was measured under different temperatures, moisture and pH values in sterilization soil, and the nitrogen fixation, phosphate and potassium solubilization were tested. The results showed that Bacillus subtilis released and propagated in a large scale under the temperature of 35℃ and 40℃, water content of 50 mL/100 g and pH 5-8, its degradation characteristics were not affected by immobilization. This study provided a theoretical basis for the application of immobilized strain in compound microbial fertilizer production.
