Denitrifying anaerobic methane oxidation process responses to the addition of growth factor betaine in the MFC-granular sludge coupling system: Enhancing mechanism and metagenomic analysis

Glycine betaine modulates extracellular polymeric substances to enhance microbial salinity tolerance

“…GB addition could increase methyl compounds, which enhances the concentration of redox substances [ 71 ]. Thus, it was reasonable to infer that the addition of GB could provide more electron transfer sites in EPS from redox secreta, which accelerated electron transfer rates.…”
