Key Points
Degradation of sodium alginate using recombinant enzyme 102C300C-Vgb yields high percentages of oligosaccharides, enhancing digestion.
Average molecular weight of degradation products is reported at 1496.36 Da, with degrees of polymerization from 2 to 4.
Application of degradation products in diets significantly increases body wall weight of Stichopus japonicus after 40 days.
Improved gut health is indicated by enhanced mucosal structure and shifts in beneficial bacterial populations.
