Abstract:
A cyanide-utilizing Yersinia species was isolated from the cyanide-bearing gold-plating industrial wastewater. Analysis of the fatty acid composition of the organism revealed that it contains large amounts of saturated fatty acids. The unsaturated hydroxy- and cyclopropyl-ring-bearing fatty acids are present in low concentrations. A comparison of the fatty acid composition with other Yersinia species shows that the genus Yersinia appears homogeneous, and that fatty-acid data of Yersiniae do not reflect the distance between Yersiniae species.
