Figure 2

Interaction effects of independent variables on the responses of pellets produced by the oat straw pretreated with TV52. (a) Interaction between particle size and fermentation time on density 0. (b) Interaction between particle size and moisture content on density 0. (c) Interaction between fermentation temperature and particle size on density 0. (d) Interaction between particle size and moisture content on the tensile strength.
