Fig. 7From: Reduced B12 uptake and increased gastrointestinal formate are associated with archaeome-mediated breath methane emission in humansMICOM model-based flux balance analysis of keystone taxa. The 40 most predictive production fluxes (metabolites) are shown for high-methane emitters on the left and low-methane emitters to the right using L1 penalized logistic regression. Black dots underneath are used to display the categorization of each metabolite into different types of metabolites. The analysis was based on 16S rRNA gene amplicon data of the matched cohort (n=30) and the identified keystone taxaBack to article page
