[Autoselection in Candida utilis yeasts in a chemostat culture].
Long-term continuous cultivation of Candida utilis in the conditions of chemostat, with the growth rate being limited with phosphates, was accompanied by autoselection. The culture obtained had a higher growth rate and differed by some physiological characteristics from the parent culture. The content of intracellular phosphates varied from 1.9 to 0.55% per dry weight, depending on the concentration of phosphates in the growth medium. At the threshold concentration (0.007 g/litre), phosphates were not virtually utilized by the culture. Specific time of transitional processes depends on the value of interfering effect.
