✦ Synopsis

Specific glucose and xylose isomerases have been identified in cell-free culture filtrates of a Chainia species.

Treatment with DEAE -cellulose selectively adsorbed xylose isomerase activity while only the glucose isomerase was adsorbed on CM-cellulose.

Glucose isomerase was completely inhibited by xylose at 1.3 x 10 -4 M concentration.

The differential identity of the extracellular glucose and xylose isomerases, unique to Chainia, is discussed.
