苯丙氨酸及苯丙酮酸对Lactobacillus sp. SK007合成苯乳酸的影响
苯乳酸 苯丙氨酸 苯丙酮酸
2009/11/13
从自然发酵泡菜中分离筛选到一株乳杆菌(Lactobacillus sp.)SK007，研究了Lactobacillus sp. SK007利用苯丙氨酸合成苯乳酸的过程，结果发现，在MRS培养基中最高可产生0.55 mmol/L苯乳酸，苯丙氨酸剩余94%，但检测不到中间产物苯丙酮酸，这表明苯丙氨酸的转氨反应是苯乳酸合成的限速步骤. 用苯丙酮酸代替苯丙氨酸作为底物可有效突破这一瓶颈，进一步优化了Lac...
热激修饰瑞士乳杆菌对Cheddar干酪成熟的影响（Effects of Heat-shock Lactobacillus helveticus on Cheddar Cheese Ripening）
