Fig. 7
LF-NMR \({T}_{2}\) distributions for coarse (a), medium (b) and fine (c) fractions with increasing water content. The x-axis is logarithmic scale, and distribution amplitude is expressed in normalized relative water content (% w/w). The letter “s” denotes the shortest \({T}_{2}\) component (\({T}_{2s}\)) at 15% MC. The correspondence (vertical dashed lines) between mesoporosity (in nm) and \({T}_{2}\) relaxation times is indicated at the top of the Figure. The shaded area, between 5 and 15 nm (associated with \({T}_{2}\) values centered around 4 ms and 30 ms, respectively), indicate the range of pore sizes available for enzyme accessibility
