Saccharide profiles of hct53 raised with 5% CO2 aeration. a Comparison of monosaccharide content between WT and hct53 under +N conditions; b comparison of monosaccharide content between WT and hct53 under −N conditions; c comparison of uronic acid content between WT and hct53 under +N conditions; d comparison of uronic acid content between WT and hct53 under −N conditions; e comparison of sulfate content and molecular weight between WT and hct53. +N, nitrogen repletion; −N, nitrogen depletion; Man, d-mannose; Rha, l-rhamnose; Glu-a, glucuronic acid; Gal-a, galacturonic acid; Glu, glucose; Gal, galactose, Ara, l-arabinose, Fuc, L-fucose. **p < 0.005; ***p < 0.0005; ****p < 0.0001. Values represent means ± SD (n = 3)
