The pectolytic bacteria Erwinia carotovora subsp. atroseptica and E. carotovora subsp. carotovora were analysed by fatty acid profiling, using a gas chromatograph and a commercial software package for data processing. A fatty acid library was built from the analysis of 261 strains of the two bacteria from different sources and countries. Independently of source or geographical origin, 98% of the E.c. atroseptica strains and 97% of the E.c. carotovora strains were correctly identified. Analysis in two separate laboratories of identical strains gave highly reproducible results. Fatty acid profiling is a rapid, reliable and reproducible method for the identification and differentiation of these bacteria.
