Effect of GalU and PGM on growth and EPS yields in MST medium
| Strain | PGM activity (U mg of protein−1) | GalU activity (mU mg of protein−1) | μmax (h−1)a | Ylactose, EPS (g mol of carbon−1)b |
|---|---|---|---|---|
| LY03 | 0.87 ± 0.03c | 5.0 ± 0.8 | 1.4 ± 0.2 | 0.17 ± 0.04 |
| TMB 6003 | 0.72 ± 0.01 | 49.1 ± 15.0 | 1.5 ± 0.4 | 0.15 ± 0.08 |
| TMB 6004 | 1.45 ± 0.02 | 9.3 ± 0.9 | 1.4 ± 0.2 | 0.31 ± 0.03 |
a
μmax, maximum specific growth rate.
b
Ylactose, EPS, yield of EPS when organisms are grown on lactose.
c
Average ± standard deviation based on the results obtained with at least two independent cultures.
