Extended Data Fig. 6: Limit-of-detection of R. gelatinosus (Bacteriochlorophyll a) on different soils.
Data are shown for R. gelatinosus YF6, which constitutively produces Bacteriochlorophyll a. a. Schematic illustrating the locations where 10 µL of cultures with varying concentrations were pipetted onto different soil types (A1, A3, A5, A7). b. RGB images from HSI data. c. Classified images from the HSI data. The dashed blue boxes indicate regions analyzed that do not contain bacteria. Classification scores in panel d are the means in the areas marked by rectangles. d. Classification scores extracted from panel c. P-values were calculated using one-sided student t-test with n = 3 (equal variance). Blue dashed regions in panels b and c only contain soil (OD600 = 0.0) and were used for the t-test. Significance scores: *** (p-value < 0.005), ** (p-value < 0.01), * (p-value < 0.05), ns (not significant). The data points are three replicates.
