Pages: 81-85
Year: Issue:  2
Journal: Journal of Nanjing Forestry University(Natural Science Edition)

Abstract: 研究了酶浓度、底物浓度、反应体系pH、反应温度、反应时间5个因素对美洲黑杨羧酸酯酶( CarE)活性测定的影响,得出测定杨树CarE的最适反应条件为:酶稀释10倍,底物浓度为3×10 -4mol/L,pH为7.0,温度30℃,时间15 min.利用试验得到的反应最适条件分析了氧化乐果、吡虫啉和氟虫腈3种内吸性药剂对杨树CarE活性的影响.结果表明:400、1600、3200和6400mg/L氧化乐...
