^aThe number of nonculturable (NC) cells added to each tube is listed. 

^bThe number of tubes which showed growth and the nature of the cultures which were obtained are listed. For example, “1+, 2−, 1 mixed” indicates that 4 of the 10 inoculated tubes showed growth, of which 1 was a pure culture of carbohydrate-positive cells, 2 were pure cultures of carbohydrate-negative cells, and 1 was a mixed culture of both carbohydrate-positive and -negative cells. 

^cNA, not applicable.
