Cellulases in bacteria

Cellulolytic bacteria can be found which produce only cell-bound cellulase such as Cytophaga (12), only cell-free cellulase, such as CelMbrio vulgaris (21), Bacillus sp. (22), Clostridium sp. (23), Acetivibrio cellulofyticus (24), and Thermoactinomyces (25,26), and both cell-bound and cell-free cellulase such as Pseudomonas (27), Bacteroides succinogenes (28), and CelMbrio futvus (29). However, the location of cellulase in bacteria is also dependent upon the environments in which the bacteria are grown and the age of the culture (29,27).
