DNA extraction efficiency as a function of cell type quantified by qPCR. Cell types are labeled as follows: B. cereus (spore), BCS, S. cerevisiae, SC, B. cereus, BC, B. thailandensis, BT, E. coli, EC. Vertical lines indicate the dispersion of the data; replicate outliers are indicated as ▲ data points. Black letters (a, b, c) indicate statistical differences within each plot, based on a Tukey’s HSD test with p < 0.05, when the outliers were excluded in the analysis. Plots are grouped by extraction method. Scales are independent for each graph due to the large range in responses
