Detection of Bacterial Endospores in Soil by Terbium Fluorescence

Figure 5

Depth profiles (0 to 25 cm) of bacterial spore content (expressed as equivalents of B. subtilis) in soil from a pasture. Comparison between autoclaving (open bars) and microwaving (solid bars) in releasing dipicolinic acid (DPA). Bars represent mean values of triplicate samples. *Sample was lost during filtration step.
