Microorganisms cultivation

Under anaerobic conditions, various pathways exist for pyravate metabolism which serve to re-oxidize the reduced hydrogen carriers formed during glycolysis. The ultimate acceptor builds up as a waste product in the culture medium. The end-products of the pathways are (1) CO, ATP, and acetate (2) COj and ethanol (3) and CO2 (4) COj and 2,3-butylene glycol (5) COj, Hj, acetone, ATP, and butanol (6) succinate and (7) lactate. The pathway that occurs depends on the microorganism cultivated and the culture.

The latter plays an important role with freeze-dried sour dough. The microorganisms cultivated on flour substrate already form a number of flavour constituents, which stick well to the flour matrix. The subsequent freeze drying preserves both, flavour and microorganisms. The resulting product saves time in the bakery and improves the quality of bread. 

Fluidized beds have been used extensively for physical operations (e.g., adsorption and heat exchanger), chemical synthesis (e.g., acrylonitrile synthesis and maleic anhydride synthesis), metallurgical and mineral processes (e.g., roasting of sulfide ores, resid hydro-treating, and reduction of iron oxide), and other applications, such as coal combustion and microorganism cultivation. 

To paraphrase this problem, it originates in the non-linear form of the microorganism cultivation. Theoretically, it is necessary for the racemate quantity fed into the reactor to be slightly lower than the total resolution activity of the microorganism at a given time. However, the total resolution activity is not fixed but is changed by various factors. Therefore, we investigated a number of ways to detect the state of the cultivation.

Biosynthesis. De novo production of an entire organic chemical molecule by a living microorganism cultivated in special vessels (fermenters or bioreactors), which allows the "monoseptic" propagation of the desired organism. Molecules of the primary (e.g., amino acids) or secondary metabolism (e.g., cytotoxics) can be the product, and the microorganism itself can be the desired product, for example, for a biotransformation or an enzyme isolated from this organism and used for biocatalysis...
