Bacteroides succinogenes

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). 

Similar approaches to cloning of bacterial xylanases have been used for genes from Clostridium acetobutylicum (30), Bacillus polymyxa (31), Bacteroides succinogenes (32), Clostridium thermocellum (33) and Pseudomonas fluorescens subsp. cellulosa (34). In each case the xylanases were predominantly located intracellularly and the levels of xylanases produced from cloned systems were, in general, very low in comparison to yeast and fungal systems. A comparison of the production yields and extent of extracellular production for various cloned xylanase genes is found in Table...
