Synergetic degradation of konjac glucomannan by γ-ray

Mannanase hydrolysis of spruce

Native konjac glucomannan harbors a glucomannan backbone while native locust bean gum galactomannan contains galactose side groups These three substrates represent mannans with different backbone compositions and decorations and were therefore interesting as model substrates in the present study on the action and substrate degradation
