Abstract: | Proteolytic activity has long been regarded as an important characteristic for distinguishing between different types of Clostridium botulinum. While all strains of Clostridium botulinum type A examined so far possess proteolytic activity, the types B and F have both proteolytic and non-proteolytic varieties. Clostridium botulinum types C, D and E were generally regarded as non-proteolytic, but different investigators have shown proteolytic activity in certain strains of these types. A summary of the classification of proteolytic enzymes in general is given and further, investigations are reviewed on the proteolytic activity in Clostridium botulinum. |
