[Comparative characteristics of the transport systems of C4-dicarboxylic acids in cultures of the genera Halobacterium and Halococcus].

The transport systems of the extreme halophilic organisms, Halobacterium and Halococcus, differ to a considerable degree in the kinetic parameters of succinate and fumarate transport, the exchange between exocellular and endocellular labeled dicarboxylates, and the rate at which labeled compounds in the cell are incorporated into cellular metabolism.
