From: Optimisation of sample storage and DNA extraction for human gut microbiota studies
Heatmap of the abundance of faecal bacteria under the different storage conditions: at room temperature (RT), + 4 °C, -20 °C new aliquots, repeated freezing and thawing (-20 °C), and up to three-week period for the different tested subjects (S1–S5). Numbers (0–3) below the heatmap correspond to the week of storage, where 0 is the control. The yellow colour in the heatmap indicates a high number of bacteria in the sample, while the dark blue corresponds to their low abundance. Blank indicates the absence of data at this point. Only 40 of the most represented bacterial genera or familiae across all individuals are shown
