  • a LPS fatty acid preparations from strains cultivated in growth medium containing 10 μM MgCl2 were sequentially analyzed by capillary gas chromatography.

  • b The results shown are averages±standard deviations of three (CS019, KCS039, KCS040, KSC045, KSC049, and KSC050) or two (KCS044) independent cultures.
