Enzymatic degradation rate of sodium alginate by recombinant VxAly7D. a Products of sodium alginate (3 mg/ml) degraded by different amounts (0, 1, 2, 6, 10, 20 U/ml) of recombinant VxAly7D for 1 h. b Time-course treatment of sodium alginate (3 mg/ml) using 6 U/ml recombinant VxAly7D at 30 °C for 0, 1, 5, 10, 20, 30, 40 and 60 min
