Abstract
An aqueous liquid composition is disclosed. The composition comprises a stabilized glucose oxidase solution having a pH of from about 6.0 to 8.0 and contains phosphate at a concentration of 1500 to 2500 mM/l. The glucose oxidase retains at least 80% of its activity after 10 days at 37.degree. C. The glucose oxidase is preferrably derived from Aspergillus niger, has a concentration of from about 5 to about 50 IU/ml and a pH range of from about 7.1 to about 7.3.
