Rhodobacter capsulatus and application thereof

The invention discloses rhodobacter capsulatus and application thereof. The collection number of the rhodobacter capsulatus AYGHJ-16 is CCTCC NO: M 2011377; the rhodobacter capsulatus belongs to photosynthetic bacteria; and through the rhodobacter capsulatus, certain organic small molecules (such as organic acid and amino acid) can be converted into growth-stimulating substances and anti-virus substances by using light energy, so that growth of plants is stimulated, and the disease-resistant immunity of the plants is improved. Moreover, through the photosynthetic bacteria, product feedback inhibition of heterotrophic microbes can be released by using organic acid produced by metabolism of the heterotrophic microbes in soil, so that a large quantity of heterotrophic microbes are propagated, and conversion and absorption of certain inorganic substances in the soil are promoted; and the photosynthetic bacteria have strong nitrogen fixation and carbon fixation effects, so more inorganic substances ...
