摘　　要：研究结果表明，在室温（30±5℃）下，乙酸乙酯、苯甲酸钠对放线菌z-6所产半纤维素酶液有防腐作用，酶液保存10d，酶活剩余50％左右；5．0％的氯化钠对青霉菌m8所产半纤维素酶液有明显防癌作用，酶液保存15d，酶活剩余57．7％。The results showed that under the room temperature (30±5℃), ethyl acetate and sodium benzoate play a certain preservative role on hemicellulase soution produced by Streptomyces z-6. About 50% of the hemicellulase activity remained after the solution has been kept for 10 days at the temperature. 5.0% of NaCl (final concentration) play evidently role on hemicellulase solution produced by Penicillium sp. m8,and 57% of enzymatic activity remained after l5 days' keeping.
