Cellulose Degrading Ability of Bacterial Strains Isolated from Gut of Termites in Vinhlong Province - Vietnam

Cellulose are the most abundant renewable biomass. The bioconversion of cellulose plays an important role for sustainable development and application in alcohol production, compost production and waste treatment. Termites were known as the most successful wood-degrading species on the earth, can deg...
