The present invention provides a method for the separation of microorganisms of a microbiological community present in a solid sample. And once the microorganisms are isolated, they are used in microbiological techniques, or their nucleic acids, both DNA and RNA, are extracted from them for carrying out molecular biology techniques. In accordance with the present invention, the method for the separation of microorganisms adhered to a solid sample comprises the following stages: Providing a solid sample with microorganisms adhered to it; adding to the solid sample a high molarity phosphate-based buffer containing a phosphate solution of a concentration greater than 0.5 M, ethanol, and a non-ionic surfactant; sonicating, and recovering the supernatant, comprising microorganisms separated from the solid sample.
