Cellulase and CBP were purified from rumen cellulytic bacterium F.. succinogenes S85, and the gene encoding xylanase C (XynC) of rumen cellulytic bacterium R. albus 7 was be the source of xylanase. The gene encoded xylanase was 62 kDa, and detected high xylanase activity. Cellulase from F.. succinogenes S85, after passing ion exchange and gel filtration columns, present two protein peaks with cellulase activity, and the molecular weight was approximately 120 and 65 kDa, respectively. CBP was eluted with sodium phosphate buffer containing 10% cellobiose and 1% CHAPS. Enzymes activity were increasing from four to ten times after addition of CBP. The result showed that CBP can effect on both cellulytic and hemicellulytic enzyme from different bacteria species and improve their enzyme activity.application/pdf202600 bytesapplication/pdfzh-TW國立臺灣大學動物科學技術學系暨研究所纖維素分解酵素聚木糖分解酵素纖維素結合蛋白質酵素活性cellulasexylanasecellulosebinding proteinenzyme activityreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/16449/1/902313B002313.pdf
