Abstract
Aqueous caffeine-containing liquids, such as coffee extracts, are decaffeinated by means of fermenting the liquid with Pseudomonad microorganisms of the type Pseudomonas putida, NRRL B-8051, Pseudomonas fluorescens, NRRL B-8052 and Pseudomonad fluorescens, NRRL B-8053 or by means of contacting the liquid with a caffeine metabolizing enzyme preparation isolated from Pseudomonad microorganisms of the aforementioned type.
