细菌蓝色素稳定性的研究

Research on the Stability of Bacteria Blue Pigment

主要讨论了温度、光照和酸碱度等8种理化因素对细菌T2013所产蓝色素稳定性的影响。结果表明,该温度（≤80℃）,p H 3.3~10.1,低强度光照,低浓度的食品添加剂和有机酸等对细菌蓝色素的稳定性影响较大,大多数低浓度的金属离子对蓝色素稳定性的影响较小,而Cu2＋和Fe3＋对蓝色素的破坏性影响较大。

The effects of eight factors, such as temperature, light and pH, on the stability of the blue pigment from T2013 were discussed. The results revealed that the bacteria blue pigment was quite stable in these conditions： certain high temperature （≤ 80 ℃）, pH 3.3- 10.1, low intensity light, low concentrations of food additives, organic acids and others. The stability of bacteria blue-pigment was rarely influenced by majority of low concentration metal ions, except for Cu2＋ and Fe3＋ that had bad effects on its stability.
