Continuous total acid determn. - in citrate fermentation solns., by cation exchange and titration

摘要

Continuous determn. of the total acid content of a citrate-contg. fermentation soln. is effected withdrawing samples of fermenter effluent by means of an automatic sampler, applying the samples to a column of strongly acidic cation exchanger, eluting the acids, and measuring the acid concn. by automatic titration. ADVANTAGE - The process is simple and gives reproducible results, allowing precise control of the fermentation process and prod. quality
