The survival properties of recombinant Lactobacillus casei 9 were studied in imitative gastrointestinal environments,such as artificial gastro fluid(pH=.～.),artificial intestinal fluid, bile(0. ～ .0(g/L)),and high concentration of NaCl(0～90 g/L).

目的探讨重组干酪乳杆菌Lactobacillus casei 9 在模拟胃肠道环境中的存活能力。 方法人工模拟胃肠道环境,即人工胃液(pH=.~.)、人工肠液、胆汁(质量浓度0. ~ .0 g/L)和高盐(质量浓度0~90g/L)。
