On the evaluation of productivity in hydrocarbon fermentation

  • A. Prokop
  • F. Štros


Direct and indirect methods of the assessment of growth rate (productivity) in hydrocarbon fermentation are briefly reviewed. The application of an indirect method, based on alkali consumption at constant pH, is discussed from the viewpoint of varying protein content in the biomass dry weight. An automatic control of substrate addition based on the indirect method is suggested.
