PURPOSE:To recover cellulase from the completely decomposed and saccharified liquid of a cellulosic substance, with simple operation, in high efficiency, by adding chitosan or a partially deacetylated chitin and a fresh substrate to the liquid. CONSTITUTION:A cellulosic substance is decomposed and saccharified with a cellulase containing at least one kind of cellulase originated from the cell of microorganism belonging to Aspergillus genus, and the cellulase is recovered from the completely decomposed and saccharified liquid by adding chitosan or partially deacetylated chitin and a fresh substrate to the liquid. Not only the cellulase originated from Aspergillus but also other cellulase can be recovered extremely efficiently by this process. |
