Comparison and Characterization of Purified Cellulase and Xylanase from Bacillus amyloliquefaciens CX1 and Bacillus subtilis B4

Cellulase and xylanase producing bacteria, Bacillus amyloliquefaciens CX1 and Bacillus subtilis B4, were isolated from horse feces and cow’s rumen fluid. Both enzymes were purified, characterized, and determined their molecular weight. The molecular weight of purified cellulase and xylanase of B. am...

Both enzymes were purified, characterized, and determined their molecular weight. The molecular weight of purified cellulase and xylanase of B. amyloliquefaciens CX1 was found to be 53 kDa and 26 kDa when cellulase and xylanase produced from B. subtilis B4 was estimated to be 46 and 23 kDa, respectively. Both cellulases exhibited their thermostability in wide range of 20-80°C and were stable over a broad range of pH 5-10.
