Abstract

Strains representing the taxa and were degraded by acid methanolysis and the non-hydroxylated fatty acid esters released were examined by thin-layer and gasliquid chromatography. The major fatty acids in all strains were 12-methyltetradecanoic ( C) and 14-methylhexadecanoic ( C) acids which occurred together with other and straight-chain acids. Polar lipids of the test strains were examined by two-dimensional thin-layer chromatography. All organisms possessed very characteristic polar lipid patterns consisting of diphosphatidylglycerol, phosphatidylglycerol and a number of uncharacterized glycolipids. The menaquinone components of the test strains facilitated their division into two groups containing, respectively, nine isoprene units (viz. and ) and eleven and twelve isoprene units (viz. ). The results of the present study indicate that the genus as presently recognized is a heterogeneous taxon containing two distinct centres of variation.
