  • a Data were generated and taken from a previous study (23), but new average profiles were calculated in light of the corrected classification of several B. stabilis strains (see text).

  • b Those fatty acids for which the average amount for all taxa was less than 1% are not given. Therefore, the percentages for each group do not total 100%. Tr, trace amount (less than 1%).

  • c The numbers in parentheses refer to the numbers of strains containing this fatty acid.
