Modelling and controlling techniques of microorganisms mean age in biotechnological processes

This paper deals with the possibility to control the biosynthesis processes using information about microorganisms mean age. The mean age is a very important parameter characteristic to every species and is tightly linked to the mechanism of producing biosynthesis products. The basic idea in controlling the biosynthesis processes using microorganisms mean age information is to bring the most microorganisms developed in the bioreactor to an optimum age. Thus they become capable of producing a large quantity of biosynthesis products. The simulation presented in this paper pertinently illustrates the viability of this method in continuous bioreactors, having as subject a population of Candida Lipolytica, cultivated on an ammonium sulphate sublayer.
