Abstract
A process of general applicability in the microbiological field wherein a culture is subjected to periods of availability and non-availability of an essential energy source such as a carbon source, i.e. the energy source is supplied in pulses. The efficiency of the culture in converting substrate carbon to cellular carbon varies depending upon the relative duration of the periods of availability and non-availability of the energy source. Thus depending upon the relative duration chosen the process can be applied differently, i.e. when the efficiency is high the process is suitable for single cell protein production while when it is low it is suitable for waste water treatment.
