Fig. 9From: Metabolic regulation of ethanol-type fermentation of anaerobic acidogenesis at different pH based on transcriptome analysis of Ethanoligenens harbinenseProposed molecular response process and metabolic pathways of E. harbinense for pH-based responses. The colors in the rectangles indicated changes of gene expression under different initial pH conditions, the blue and red represent the down-regulation and the up-regulation, respectivelyBack to article page
