Table 1. Elemental Composition and Protein Content of EPSa.
O (%) | N (%) | H (%) | C (%) | S (%) | protein content (mg/mL) |
---|---|---|---|---|---|
76.0 ± 2.4 | 1.1 ± 0.6 | 2.6 ± 0.4 | 13.1 ± 1.3 | 7.4 ± 0.2 | N.D. |
Elements were measured by an elemental analyzer. Oxygen % was calculated by subtracting the % of the other elements from 100%. % are expressed as mg of each element/mg of analyzed EPS. Protein content was measured by colorimetric assay.
