Sucrose hydrolysis performance of the free and immobilized preparation was determined by measuring the glucose content of the medium according to a method described previously (Arıca et al., 2000a).
Assay mixture contained GOD (25 mg), POD (6.0 mg) and odianisidine (13.2 mg) in phosphate buffer (100 ml, 0.1 M, pH 7.0). An aliquot (2.5 ml) of assay mixture and
0.1 ml of enzymatically hydrolyzed sample were mixed and then incubated at 35C for 30 min in a water bath.
After addition of sulphuric acid (1.5 ml, 30%) absorbance was measured in a UV/Vis spectrophotometer (Shimadzu, Model 1601, Tokyo, Japan), at 525 nm.
