Transport of Metabolites in Microorganisms

This paper describes, not ionic movement, but rather the transferof organic nutrients from environment to cell in microorganisms.A section on methods for studying such transfer is followedby a discussion of generalized models derived from kinetic data.Control mechanisms, involving regulation of synthesis of membraneproteins and feedback modification of their activity, are described.Some recent work on specific models for transport of amino acidsand carbohydrates is also discussed.
