Microbial Biotechnology

General

Course Contents

Lectures

  • Stages of biotechnological processes.
  • Submerged fermentations – Bioreactors (kinetics of microbial growth and metabolites, types of bioreactors, design, operation, control, factors regulating fermentation processes, optimization and scale-up).
  • Microbial biosynthesis – Production of metabolites (food and feed additives, vitamins and amino acids, lipids, industrial enzymes, etc.).
  • Solid state fermentations – Biotechnological utilization of plant biomass by microorganisms. Biodegradation, detoxification of agro-industrial wastes and bioconversions of agricultural by-products.
  • Downstream processing methods for the recovery and purification of extracellular and intracellular biotechnological products.
  • Methods of cell immobilization.
  • Cultivation of edible and medicinal mushrooms – Production, utilization of biomass and secondary metabolites.
  • Biotechnological methods for of waste and by-products’ valorization.

Laboratory exercises:

  • Growth of microorganisms in shake flasks.
  • Determination of microbial growth by the turbidity method.
  • Determination of biomass dry weight.
  • Study of microbial growth kinetics, calculation of product yield and productivity, calculation of specific growth rate.
  • Methods for determining sugar consumption in microbial cultures.
  • Cell immobilization.
  • Solid state fermentation.
