본발명은폭쇄전처리된소나무바이오매스를트리코더마속 KMF006 균주(KCTC13500BP) 유래셀룰레이즈를이용하여처리하여당화시키는것을특징으로하는소나무바이오매스의당화방법에관한것으로, 본발명에따르면, 당화가어려웠던폭쇄처리된소나무바이오매스를보다효과적으로당화시킬수 있어, 바이오연료생산에유용하게이용될수 있다.
Abstract:
PURPOSE: An extracellular enzyme which is prepared by culturing Fomitopis palustris in a culture medium containing ligneous biomass, especially rice straw, a method for producing the same, and a method for saccharifying the biomass are provided to enhance cellulase activity. CONSTITUTION: A saccharifying method for producing bioethanol comprises: a step of adding Fomitopis palustris-derived extracellular cellulase into a culture medium containing a rice straw substrate as a carbon source; and a step of saccharifying at 45 deg. C and pH 4.5-5.0 or adding Tween20. A saccharified material for producing bioethanol is prepared by the method. The saccharifying ability of the Fomitopis palustris-derived extracellular cellulase is improved in rice straw with low crystallinity of cellulose.
Abstract:
PURPOSE: A Porodisculus pendulus-derived diastatic enzyme and a method for producing biofuel using the same are provided to ensure excellent saccharification performance. CONSTITUTION: A method for producing Porodisculus pendulus-derived diastatic enzyme comprises: a step of culturing Porodisculus pendulus strain in a culture medium containing cellulose, corn powder, or peptone/yeast extract mixture at 25-30°C and pH 5.5-6.0; and a step of isolating the diastatic enzyme from the culture liquid. A used biomass is cellulose or rice straw.
