Gram-negative, nonfermentative bacteria isolated from biofilters for off-gas treatment of animal-rendering-plant emissions were differentiated by whole-cell fatty acid analysis, quinone analysis, and...
Hirata, Hajime, Altendorf, Karlheinz, Harold, Franklin M.
Membrane vesicles from E. coli can oxidize D-lactate and other substrates and couple respiration to the active transport of sugars and amino acids. The present experiments bear on the nature of the...
Bertrand, Jessica, Altendorf, Karlheinz, Bramkamp, Marc
When grown under conditions of potassium limitation or high osmolality, Escherichia coli synthesizes the K+-translocating KdpFABC complex. The KdpA subunit, which has sequence homology to potassium...
