Abstract excerpt
We found that incubation of probiotic Lactobacillus casei BL23 in milk at 4 °C prior to ingestion increased its survival in the mammalian digestive tract. To investigate the specific molecular adaptations of L. casei to milk, we used tandem mass spectrometry to compare proteins produced by L. casei BL23 at 4 °C in milk to those in exponential and stationary phase cells in laboratory culture medium at either 37 or...
