Fig. 3: The carbon flow and microbial composition in CH4/CO2-metabolizing consortia.
From: Electrochemically coupled CH4 and CO2 consumption driven by microbial processes
a The carbon flow of the proposed process, in which CH4 and bicarbonate were converted into different carbon fractions. b The composition of CH4-oxidizing consortia before and after iron reduction. c The composition of CO2-reducing consortia before and after iron oxidation. Data generated from n = 3 biologically independent samples for each group.
