although aldehyde fixation appeared to be important in elicitation of the peroxidatic activity of catalase , the final pigment production after 60 min incubation was optimal with the lowest concentration of glutaraldehyde ( 1 % ) , after the shortest fixation period ( 30 min ) , and at the lowest temperature ( 5 degrees c ) tested .
