602 Marine Microbiology 



Table 2 shows the results from Cruises 3, 4, and 5. The chitin 

 agar plates from Cruise 3 showed no chitin degradation by the 

 flora sampled before crushing, while in several cases the micro- 

 flora sampled after crushing completely hydrolyzed the chitin 

 from the agar plates. There were no instances of discrete clear 

 zones around colonies, but complete clearing of the plates oc- 

 curred. 



On Cruise 5 the procedure was repeated, and an especially
