BACTERIA IN DECOMPOSING SALMON 93 



Of the 10 cultures described in table 4, 3 were identified as 

 Bad. cloacae although in the case of 323 and 380 the methyl-red 

 and the Voges-Proskauer tests are not typical. Repeated 

 plating and testing of these two cultures did not alter the results 

 of these tests and 323 and 380 have necessarily been recorded as 

 atj'pical strains. Culture 31GB cannot be confirmed as BacL 

 cloacae since it does not ferment sucrose. In all other reactions 

 it is similar to Bad. cloacae. One culture, 397, in table 4 is a 

 spore-forming organism which does not ferment any of the 

 sugars; one culture, 395, ferments glucose with the production 

 of acid but no gas; one culture, 354, produces acid in glucose and 

 sucrose and three cultures, 399, 400 and 513^, produce acid 

 in glucose, lactose and sucrose. Culture 513^ is a streptococcus. 



In table 5 one culture, 525, was identified as Bad. communior, 

 one, H2, as Bad. aerogenes and two, 343 and 523, as Bad. coli, 

 although 343 is atjpical in that it gives a positive result in both 

 the methyl-red and the Voges-Proskauer reactions. Culture 

 503 produces acid and gas in glucose and gives a positive methyl- 

 red test. Three cultures are streptococci, two of which, 516 and 

 518, produce acid in glucose, lactose and sucrose and one of 

 which, 510, produces acid only in glucose and lactose. One 

 culture, 406, produces an acid fermentation in glucose. The 

 two remaining cultures in this table, 314a and 410, show no 

 fermentative reactions. 



Among the pigment producing bacteria described in table 6 

 are two strains of Ps. fluorescens, 325 and 374. Culture 374 

 differs from 325 only in its failure to produce indol. Four of the 

 cultures in this table show no fermentative reactions. Culture 

 401 produces acid in glucose and culture 403 has an acid fermen- 

 tation in glucose, lactose and sucrose. 



Of the 11 cultures from canneries described in table 7, two, 

 417 and 419, were identified as Bad. cloacae, although 419 must 

 be recorded as atypical inasmuch as it gives negative results with 

 both the methyl-red and the Voges Proskauer reactions. Two 

 cultures, 471a and 473, produce acid in glucose, lactose and 

 sucrose and one culture, 429, produces an acid fermentation in 

 glucose only. The remaining six cultures in this table show no 

 fermentative reactions.
