2112 Antagonistic soil bacterium Pseudomonas fluorescens and biological control using the same

摘要

The present invention relates to Pseudomonas fluorescens 2112 ( Pseudomonas fluorescens 2112) and a biological control method using the same. By inhibiting RNA synthesis and protein synthesis of phytopathogenic fungi by producing sex antibiotics and siderophores, they inhibit the growth of phytopathogens and maintain phytopathogenic activity, especially at acidic pH and high temperature. Also has excellent effects to maintain its activity.
