DISRUPTION OF BIOMASS BY ENDOGENOUS PRESSURE GENERATION FROM FERMENTATION

摘要

The present invention relates to a method of disrupting biomass by an abrupt pressure release. For disrupting biomass, in particular as pretreatment of biomass for improved degradability, in an environmentally friendly manner, without harsh chemical substances and with reduced energy input and costs, the inventive method performs the steps of fermenting the biomass with a microorganism or with a consortium of microorganisms producing gas in a vessel, said gas increasing the pressure in the vessel; and disrupting the biomass by abruptly releasing the increased pressure.
