ABSTRACT:
The present invention relates to the coarse clarification of lysed cell material from microorganisms and particularly to a method of obtaining nucleic acids. In certain embodiments, the present invention provides a method of coarsely clarifying cell lysate from microorganisms that comprises: lysing the microorganisms under the normal atmospheric pressure to form a flocculent precipitate in the lysate, compressing the flocculent precipitate in the lysate by reducing or increasing the pressure of the atmosphere surrounding the lysate in relation to the normal atmospheric pressure to form a compressed flocculent phase and a liquid phase, and separating the two phases.
