It is generally assumed that younger soil is inhabited by more opportunistic (r-selected) communities. In our research we examined the opportunism of soil bacterial communities from six fallow fields, which represent a young ecosystem under succession, six meadows, which represent a stable ecosystem, and four sites transitional between fallow and meadow fields. Culturability was calculated from the ratio of Colony Forming Units from agar R2A plates to the total number of cells from epifluorescence microscopy. To compare the rate of growth, colonies were counted on plates every day for seven day. Additionally, the results obtained from agar inoculations were compared with soil microbial communities PLFA profiles. There were no differences in the culturability ratio of soil bacterial communities between ecosystems.
