PROCESS PARAMETERS OF AEROBIC SYNTHESIS
OF MICROORGANISMS
Introduction. The development of technologies based on microbiological cultures
in the world is aimed at their concentrated production. The advances in biological and
engineering sciences make it possible to create high-performance equipment and
technology based on industrial methods of controlling the processes of microbiological
production. The latter concerns the production of food and feed products, medicines, and
organic substances. The list of the most known and widespread products includes feed
proteins, amino acids, enzymes, vitamins, antibiotics, substances for biological protection
of plants, bacterial fertilizers, etc.
Microbiological support requires the creation of special laboratories for each food
production enterprise, and in some cases, separate specialized associations are set up.
Their activities begin with using museum cultures of microorganisms. Biotechnology is
closely linked to technical microbiology and biochemistry. Biotechnology uses many
methods of chemical technology, especially in the final stages of production during the
separation of synthesized components from culture media or biomass of microorganisms.
The implementation of microbiological synthesis means the cultivation of the
selected culture of microorganisms in a nutrient medium of a certain composition with the
adherence to the relevant technology and powerful restriction or even complete exclusion
of undesirable microorganisms. Sometimes the execution of the latter requires
overcoming complex technical barriers. For example, aerobic synthesis of bakery yeast in
sugar-containing media requires continuous aeration of up to several thousand cubic
meters per hour. It is obvious that this precludes the aseptic preparation of incoming air
streams at a high level of existing requirements.
The development of technological equipment is continuous, as with all technologies.
Significant volumes of culture media that exist as gas-liquid compounds mean the need
for further study of their hydrodynamics, the structure, kinematics, and dynamics of
circuits, determination and control of gas retention capacity, air and energy costs,
conditions of heat and mass transfer processes, temperature stabilizations, use of
secondary energy resources, and limitation of harmful environmental impacts. Along with
this, the main requirement is the productivity with high quality of products and minimized
