 animals. On the other hand, organisms isolated from invertebrates 

 showed greater and consistent incidence of anaerobic glucose dis- 

 similation and polysaccharide (starch) hydrolysis.

Fig. 4. A comparison of biochemical and physiological activities of bacteria 

 associated with vertebrates and invertebrates. 



The physiological properties of Pseudomonas and Achromo- 

 bacter sp. isolated from vertebrate and invertebrate marine ani- 

 mals were studied in detail ( see Table 5 ) in an effort to relate the 

 general picture of metabolic functions of the bacterial populations 

 to the major groups of bacteria isolated. The Pseudomonas sp. 

 from both animal groups were relatively similar, but greater 

 overall activity of Pseudomonas sp. from vertebrate animals was 

 noted. Achromobacter sp. yielded no distinguishable pattern
