Effect of particle size on the enzymatic hydrolysis of polysaccharides from ultrafine lignocellulose particles
- 105 Downloads
The efficiency of the enzymatic hydrolysis of wood polysaccharides ground into ultrafine particles (UFPs) has been investigated. The content of reducing sugars (RS’s) in powdered raw materials and the yield of sugars during enzymatic hydrolysis have been shown to depend on the particle size. Laser interference microscopy and dynamic light scattering studies have shown that increasing the grinding time from 20 to 40 min resulted in the formation of particles ranging from 2 to 200 nm in size. Enzymatic hydrolyzates of UFPs mostly contained glucose and galactose. The grinding intensity (mill rotation rate) and time had a significant effect on the extent of the enzymatic hydrolysis of wood.
