(1) Bacterial cellulase was newly obtained as powder, by salting out with ammonium sulphate from the cell-free enzyme solution prepared from an aerobic mesophilic cellulose-decomposing bacterium (Pseudomonas fluorescens var. cellulosa UEDA et ASAI) and then its optimum pH (6.5), optimum temperature (37°C), and inactivation pH and temperature were decided. (2) From the facts that a large amount of reducing sugar is produced from cellulose and that the nature of the residual cellulose is scarcely affected by the action of this enzyme solution, it is considered that this enzyme does not belong to “weathering” cellulase the name of which was first proposed by TERUI and FUJIWARA, but belongs to “hydrolytic” cellulase.
