This study was conducted to compare the cellular fatty acid composition and genotypic analysis of Bifidobacterium longum MK-G7 originated from Koreans with other commercial type strains of bifidobacteria. The cellular fatty acid of Bif. longum MK-G7 was shown to be composed of $C_{160FAME},C_{181\;c18DMA},C_{18.1\;CIS9\; FAME},C_{14.0FAME},C_{19\;0cye9,10 DMA},Feature7(C_{17.2 FAME), and Feature 10(C_{181\; Cll/t9/t6 FAME}$. Bif. longum MK-G7 showed 99.9% homology and the highest relatedness with Bif. longum ATCC 15707 type strain. Both Bif. longum MK-G7 and Bif. longum ATCC 15707 showed 153 bp products on RAPD (randomly amplified polymorphic DNA) analysis, however, they showed quite different band patterns on PFGE (pulsed-field gel electrophoresis) analysis. Consequently, our present study showed that Bif. longum MK-G7 was different from any commercial type strains of Bif. longum tested.
