Dataset link Gene expression profile of Lactobacillus casei Zhang in fermented milk during transit in simulated gastrointestinal tract

Experimental Protocol


Twelve samples of bacterial cells in the absence and presence of fermented milk were collected at 3 h in simulated gastric juice, 4 h and 8 h in intestinal juice, 2 biological replicates were obtained in each time point. The average of the normalized expression values of the 2 biological replicates for each probe was regarded as the expression value of a predicted gene. To identify the expression pattern of each gene across different treatments, n-fold change ratios were calculated for every gene in pure L. casei Zhang versus L. casei Zhang in fermented milk.
