Abstract	In soil microbiological studies, the storage conditions of the soil samples prior to analysis may be decisive for the results. Studies made on freshly collected soils are generally preferred but these are not always possible for pratical reasons. The most commonly used methods to store soils for microbiological analysis are refrigeration or freezing of field moist soil. There are, however, studies that warn against any kind of storage, although other studies do not indicate any drawbacks to it. In this study the refrigeration and freezing with or without cell membrane stabilizer, were tested in storage until 292 days, in soil with or without petroleum contamination. The storage effects were assessed on fungi and bacteria population. The results showed that the effects of freezing generally were smaller than those of refrigeration and that this last do not be recommended to storage of soil contaminated with petroleum.
