The control (CNT), agsA disruption (DagsA), agsB disruption (DagsB), double-disruption (DagsA-DagsB), CagsB, and CagsB with agsA disruption (CagsB-DagsA) strains were cultured in CD liquid medium (agsB-repressing conditions for the CagsB and CagsB-DagsA strains). Monosaccharide compositions are reported for the (A) hot-water-soluble (HW), (B) alkali-soluble 1 (AS1), (C) alkali-soluble 2 (AS2), and (D) alkali-insoluble (AI) cell wall fractions (see Figure S4) as a percentage of the total dry weight of each fraction. Error bars represent the standard deviations calculated for at least three replicates. *, significantly different from the control (P<0.01).
