title: Lack of chemotactic response to tricarboxylic acids by Escherichia coli carrying a plasmid determining citrate utilization.
abstract: Salmonella typhimurium but not citrate-utilizing Escherichia coli carrying the Cit plasmid showed positive chemotaxis to tricarboxylic acids, indicating that the Cit plasmid encodes a transport system but not a chemoreceptor for citrate.
