Introduction:
Bacillus megaterium� is a Gram-positive, rod-shaped, spore-forming bacterium that is widely distributed in various ecosystems, including soil, seawater, and decaying organic matter. Its name, derived from "mega" (large) and "terium" (creature), reflects its substantial sizeâ??up to 4 �µm in lengthâ??making it one of the largest known bacteria.

Functionï¼?
It can dissolve calcium phosphorus, iron phosphorus, aluminum phosphorus and other compounds in the soil that are difficult for crops to absorb, promote the dissolution and utilization of ineffective phosphorus in the soil, thereby improving the utilization rate of fertilizers; through competitive growth and the production of secondary metabolites that are harmful to pathogens, it can inhibit the growth and reproduction of various pathogens.
