Bacterial species are listed in decreasing order of germicidal efficiency.
GE, germicidal efficiency, calculated as log10(N/N0 per J cm−2). Values including percent uncertainty are for the experimental results in this study (calculated using GE values to three decimal places). A value of 0% uncertainty indicates no differences in the calculated GE values.
