Abstract

A bacterial strain, Curtobacterium sp., isolated from a soil with zinc added possessed ω-cyclohexyl fatty acids. ω-Cyclohexyl undecanoic acid made up 47% of the total fatty acids; it was the most abundant fatty acid in the strain grown in tryptone medium. 12-Methyl tetradecanoic acid (23%) and 14-methyl hexadecanoic acid (22%) were also major fatty acids. The proportion of ω-cyclohexyl undecanoic acid increased as the pH of the medium decreased and as the culture temperature increased.

The bacteria grew almost normally in zinc-enriched medium, and ω-cyclohexyl undecanoic acid increased with zinc concentration. Zinc added to the medium was not abundant in the cell fraction, and the ratio of increase of zinc in the cells was not so high as in the culture medium. These results suggested that ω-cyclohexyl fatty acids are related to the zinc tolerance of the isolated strain, and that this tolerance depends on low permeability of the membrane to zinc.
