Project description:Investigation of the overall in vitro response of Bacteroides thetaiotaomicron to human milk oligosaccharides. Comparison with response to MM-lactose and MM-galactose (Analysis performed using as a baseline datasets GSM301635 and GSM301637 corresponding to Bacteroides thetaiotaomicron response in MM-Glucose) In vitro transcriptional profiles of Bacteroides thetaiotaomicron obtained from biological duplicate cultures taken: (i) at middle log phase in minimal media galactose (MM-Gal) and minimal media lactose (MM-L) and (ii) at two timepoints during log phase in minimal media human milk oligosaccharides (MM-HMO).

Project description:Transcriptional profiling of Bacteroides thetaiotaomicron was performed on samples taken from (i) chemostat cultures (in vitro) and (ii) from the ceca of gnotobiotic monoassociated NMRI mice (in vivo). In vitro profiles were obtained from biological duplicate cultures taken at five timepoints from log to stationary phase in three types of media: (i) minimal media glucose (MM-G), (ii) minimal media maltotriose (MM-M), and (iii) rich media (TYG). In vivo profiling was performed on 12 mice, each colonized with B. thetaiotaomicron for ten days. The in vivo profiling was conducted in two separate experiments: (i) 6 male NMRI mice fed standard polysaccharide rich mouse chow and (ii) 3 male NMRI mice fed standard polysaccharide rich mouse chow and 3 male NMRI mice fed a simple sugar diet containing glucose and sucrose but deficient in polysaccharides.
