Fig. 4From: Saccharomyces cerevisiae employs complex regulation strategies to tolerate low pH stress during ethanol productionThe significantly enriched KEGG pathway at pH 2.5 (P ≤ 0.05). The enrichment ratio of each KEGG term was the number of DEGs involved in each KEGG term to the number of total genes involved in each KEGG term. B3, C3, and BC3 indicated groups B3 vs KF-7, C3 vs KF-7, and BC3 vs KF-7, respectivelyBack to article page
