Title:
ENZYMIC SACCHARIFICATION METHOD OF BIOMASS FOR MINIMIZING GENERATION OF METABOLITE OF CONTAMINATED MICROORGANISMS, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/163622
Kind Code:
A1
Abstract:
The present invention provides a method for terminating enzymic saccharification by detecting, at an early stage, an organic acid which is generated in the case that unwanted microorganisms contaminate the process of enzymic saccharification of biomass or pretreated materials of the biomass, and an apparatus for implementing the same. The method and apparatus of the present invention for maximizing the saccharification rate during the enzymic saccharification of biomass or pretreated materials of the biomass detect, at an early stage, generation of an organic acid through contamination by unwanted microorganisms during enzymic saccharification so as to convert operating conditions of the enzymic saccharification apparatus such that the growth and development of the microorganisms are strongly restrained, thereby maximizing the saccharification rate and allowing for preparation of biosugar which contains hardly any microorganism metabolites.
