They can be found in many alternative kinds, such as qualitative and quantitative formats. Quantitative reference materials have a defined range of viable microorganisms and so are normally a freeze-dried or gel suspension provided which has a Certificate of research (COA) specifying the volume of practical microorganisms that should be recoverable.
