摘要
研究多种因素对短小杆菌酶催化Ｌ－天冬氨酸（Ｌ－Ａｓｐ）和Ｌ－苯丙氨酸甲酯（Ｌ－ＰｈｅＯＭｅ）合成二肽甜味剂Ａｓｐａｒｔａｍｅ能力的影响。结果表明，反应最适ｐＨ为６．０，最适温度为４０℃，反应１０ｈ，催化能力为０．４７５ｇＡＰＭ／ｇ菌体，产率８０．５％，收率８１．０５％。
Aspartame can be synthesized with Bacillus pumilus,the influence of different factors on enzymatic synthesis reaction were studied.The optimum pH is 6.0,temp is 40℃,the catalytic ability is 0.475g APM/g,the yield is 80.5%.
