제목 Ethanol production using glucose/xylose mixture by P. stipitis mutants
초록 To develope the process of bioethanol production, Immobilized Cell Reactor (ICR) was performed with glucose/xylose mixtures by Saccharomyces cerevisiae and Pichia stipitis. However S. cerevisiae cannot ferment xylose and P. stipitis is relatively low in ethanol tolerance compared with S. cerevisiae. To overcome this problem, we designed the continuous process which xylose was first utilized by P. stipitis mutants and then residual glucose was used by S. cerevisiae. Also, we developed the strain, which was developed based on P. stipitis transformation system using antisense technology and selected P. stipitis mutants exhibiting a decreased ability to consume glucose.
