Dynamics of mixed cultures of Lactobacillus plantarum and Propionibacterium shermanii
Abstract:
The mixed culture of Lactobacillus plantarum and Propionibacterium shermanii grown anaerobically in glucose minimal medium exhibits features typical of a commensal interaction even though a number of complicating factors, such as a large maintenance requirement of L. plantarum and inhibition of growth of P. shermanii at low pH, are present. A simple mathematical model of the system is presented and is shown to reproduce rather well some of the features of the continuous mixed culture system in both steady-state and transient situations.
