Determination of lignin degradation rate of knock-out mutant mutants and complementary strains in strain QL-Z3. Blue: wild type (WT), yellow: knock-out mutants, red: complementary strains. a EDYP_48 wild type, knock-out mutant and complementary strain; b ELAC_205 wild type, knock-out mutant and complementary strain; c EDIO_858 wild type, knock-out mutant and complementary strain; d EOXI_996 wild type, knock-out mutant and complementary strain; e ESOD_1236 wild type, knock-out mutant and complementary strain; f EMON_3330 wild type, knock-out mutant and complementary strain; g ECAT_3467 wild type, knock-out mutant and complementary strain; h EMCAT_3587 wild type, knock-out mutant and complementary strain. a, b, c: significant difference (*p ≤ 0.05) (ANOVA analysis). Average values of three replicates are shown with the standard errors of the mean shown as error bars. Each experimental group was conducted in triplicate
