A method of disrupting biological material includes drying particulate material, mixing the material with a gas under pressure, releasing the pressure explosively and collecting the resultant product. The biological starting material is any particulate material and includes: cells with membranes, cells with rigid cell walls, non-cellular biological material, intra-cellular material, and unbounded homogenous material. Apparatus for batch, semi-continuous and continuous operation of the method is provided. Included is a chamber with at least one inlet valve and at least one outlet valve and collection means. The chamber is capable of withstanding at least 800 bar, preferably 30 bar pressure. The particle size of the starting material is in the range 0.1 to 2000 mum and of the resultant product, less than 2 mum. |
