Experimental Evaluation Of Ecological Principles To Understand And Modulate The Outcome Of Bacterial Strain Competition In Gut Microbiomes, Rafael R. Segura Munoz, Sara Mantz, Ines Martinez, Fuyong Li, Robert J. Schmaltz, Nicholas A. Pudlo, Karthik Urs, Eric C. Martens, Jens Walter, Amanda Ramer-Tait

Department of Food Science and Technology: Faculty Publications

It is unclear if coexistence theory can be applied to gut microbiomes to understand their characteristics and modulate their composition. Through experiments in gnotobiotic mice with complex microbiomes, we demonstrated that strains of Akkermansia muciniphila and Bacteroides vulgatus could only be established if microbiomes were devoid of these species. Strains of A. muciniphila showed strict competitive exclusion, while B. vulgatus strains coexisted but populations were still influenced by competitive interactions. These differences in competitive behavior were reflective of genomic variation within the two species, indicating considerable niche overlap for A. muciniphila strains and a broader niche space for B. vulgatus …

Impact Of Calcium Ion (Ca2+) On Pectin Wall Material For Microencapsulated Lactobacillus Plantarum, Nurul Hasniah

Chulalongkorn University Theses and Dissertations (Chula ETD)

The microencapsulation, a promising technology, could preserve the probiotic viability during processing, storage, and delivery to gastrointestinal tract through the wall layer. However, the loss of probiotic depends on heat/stress-susceptibility of culture themselves and the microencapsulating efficiency of wall materials. The selection of wall material composition is very challenging. Maltodextrin (MD) is mostly selected for the microencapsulating application because of its low price, rapid water solubilization, and low viscosity. MD functions as a good medium but not stabilizer for culture. Pectin is the most abundant biopolymer, found in plant cell. Pectin itself is a good gelation agent so it could …
