Abstract

The invention discloses pantoea for degrading organic phosphorus and inorganic phosphorus and application of the pantoea. The preservation number of the pantoea (Pantoea sp.)S-32 in a general microorganism center of the China Committee for Culture Collection of Microorganisms is CGMCC No.10017. According to the pantoea, the phosphorus solubility for degrading calcium phosphate reaches 24.19% and is equal to 3.64 times of that of bacillus megatherium As1,223; the phosphorus solubility for degrading lecithin reaches 2.47% and is equal to 1.46 times of that of bacillus megatherium As1,223; the pantoea has relatively strong environmental suitability and can adapt to relatively wide ranges of temperature, pH value and salinity. Experiments prove that the pantoea (Pantoea sp.)S-32 CGMCC No.10017 can serve as a strain resource of microbial fertilizers so as to increase the crop yield and accelerate the ecological restoration of soil of mining areas.

Description

technical field

[0001] The invention relates to a pantoea that degrades organic phosphorus and inorganic phosphorus and its application in the field of biotechnology. Background technique

[0002] Phosphorus is one of the essential nutrient elements for plant growth. Its importance is second only to nitrogen, accounting for about 0.2% of plant dry weight. It is the main component involved in energy metabolism, nucleic acid and cell synthesis, and some enzyme regulation, and it plays an important role in promoting plant growth. Development and metabolism play important roles and are irreplaceable components in the ecosystem.

[0003] The average phosphorus content in the soil is about 0.05% (w / w). The phosphorus in the soil exists in two states of inorganic and organic compounds, but only 0.1% of the phosphorus can be used by plants, which becomes a limiting factor affecting plant growth. factor. Among them, insoluble organic phosphorus generally accounts for 20%-50% of the...
