Yield of each fraction obtained by alkali treatment of the control (CNT), agsA disruption (DagsA), agsB disruption (DagsB), double-disruption (DagsA-DagsB), conditional-agsB (CagsB), and CagsB with agsA disruption (CagsB-DagsA) strains.

aThe yield of each fraction is expressed as the percentage of the total dry weight. Values represent the mean of triplicate measurements. Fractions: HW, hot-water-soluble; AS, alkali-soluble; AI, alkali-insoluble. Figure S4 shows the fractionation process.
