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.
