[Balanced and unbalanced growth of periodic and continuous cultures of Candida utilis].

The paper presents mathematically treated data published in literature about the specific growth rate mu and the economic coefficient Y in Candida utilis at the exponential growth phase, at the transient state in chemical from the limitation of growth with a source of carbon and energy to the inhibition with low pH values, and at the stationary state in chemostat. Both parameters show attenuated oscillations in the first two cases, but are constant in the third case. The oscillations of mu and Y are synchronous and their interrelationship is directly proportional. The values of Y may be negative since the cell weight can decrease though the cell still assimilates the substrate. The specific rate of substrate assimilation in oscillations remains constant. Proteins can by synthesized at two different rates while the growth rate is one and the same.
