Microcalorimetric study of pretreatment of straw

Summary Anaerobic microbial decomposition of straw samples is investigated by microcalorimetry and g.c. analysis of the metabolic products. Interaction between the endogenous flora of the straw and the added inoculum is considered. The effects of (KOH) pretreatments (0.25 - 0.5 - 1 m) and of the resulting salt were estimated by the fermentation products and microcalorimetry.
