Abstract
A process for obtaining citric acid, characterized in that e. Coli kg 93, f is grown in a first stage for 15-24 hours at a temperature of 20-37ºC and at a ph of 5.0-7, 5 on a substrate consisting of serum permeate to which phosphates have been added in a concentration of 0.8-1.6 g/liter and nitrates in a concentration of 0.8-1.2 g/liter or a corresponding amount of urea, and by the fact that h. Wickerhamii cbs 4308 is grown in a second stage for 20-26 hours at a temperature of 15-35ºC and at a ph of 4.5-6.5 in the culture solution from the first stage, after which citric acid is obtained from the culture solution in a manner known per se.
