CELLULAR FATTY-ACID COMPOSITIONS OF ACHROMOBACTER GROUP-B AND GROUP-E

Strains of "Achromobacter groups B and E" were examined for cellular fatty acid (CFA) composition to evaluate their chemical relatedness to known bacterial species and groups. The CFAs were liberated from whole cells by base hydrolysis, methylated, and analyzed by capillary gas-liquid chromatography. The CFA profiles of the two groups were identical and were distinct from CFA profiles of all other bacteria we have previously tested. These data provide support for results from whole-cell protein pattern analysis and DNA-DNA and rRNA-DNA hybridization studies, which show that "Achromobacter groups B and E" are biotypes of a single new genus and species.
