In this article, we consider the growth of microorganisms on mixtures of carbon sources and characterize the consumer‐resource relationship for this system. The characteristic features observed for the growth of a single microorganism on a pair of carbon sources allow a representation of this relationship based on a general paradigm for resource classification. This representation is verified using a comprehensive model for microbial growth on carbon sources. The results show that for the same pair of carbon sources the qualitative nature of the consumer‐resource relationship changes with changing specific growth rate, and therefore a change in the identity of the rate‐limiting substrate(s). © 1997 John Wiley & Sons, Inc.
