Change in the Crystallinity of Wheat Straw during Ozone Treatment

A new way of diffractometrically measuring the degree of crystallinity of substances by determining the rate of change in function I = f(2θ) over the range of scattering angles of a test sample’s diffractogram is used to study changes in the crystallinity of wheat straw during ozone treatment. It is shown that the crystallinity of a sample is inversely proportional to its content of lignin. No correlation is found between the crystallinity of the lignocellulosic substrate and its reactivity in the processes of enzymatic hydrolysis to sugars.
