In order to improve the activities of mycelium-bound ester hydrolases of Aspergillus oryzae Cs007, the main production conditions were investigated. The activities of the ester hydrolases were simultaneously determined by titration assay and spectrophotometric assay methods, using olive oil and p-nitrophenyl esters as substrates, respectively. The optimum carbon source and nitrogen source were ...
