Pfizer., o Pioneers in Citric Acid by Fermentation

.· 5

© In 1923 after many years of research, Pfizer inaugurated commercial production of Citric Acid by the fermentation process, making available to American industry for the first time a reliable supply of this important acid. Prior to the Pfizer fermentation process, the manufacture of Citric Acid depended mainly on imported citrate of lime. When this crude material was in short supply, the manufacture of Citric dwindled and prices were forced upward. The new Pfizer process, based on the vegetative fermentation of sugar, resulted in a product of the highest quality. Readily available raw materials and the new improved process enabled Pfizer to reduce the price of Citric. Since the price has remained consistently l o w . . . e v e n through World W a r II and the post-war years ...manufacturers have found this nontoxic acid increasingly economical to use. And as its popularity has grown, Pfizer has expanded production facilities to meet all demands.
