 ::::::dd. Attack cellulose
 * e. Acid produced in milk.


 * ee. Milk unchanged.


 * cc. Grow readily at 25° C. but poorly or not at all at 37°C.
 * d. Action on cellulose unknown or unreported.
 * e. Alkaline reaction in milk. Attacks riboflavin converting it to lumichrome.


 * ee. Reaction in milk unknown or unreported.
 * f. Nitrates reduced to elemental nitrogen.


 * ff. Nitrates reduced to nitrites. Indole decomposed with formation of blue crystals of indigotin.


 * dd. Attacks cellulose.


 * B. Sea-water and brine forms (a few are pathogenic).
 * 1. Produces pigments which are soluble in culture media. Gelatin liquefied.


 * 2. Pigments soluble in culture media not produced.
 * a. Gelatin liquefied.
 * b. Polar flagellate.
 * c. No growth in milk.
 * d. Indole produced; nitrites produced from nitrates.


 * dd. Indole not produced; nitrites not produced from nitrates.
 * e. Produces hydrogen sulfide and ammonia from tryptone: no acid from glucose.


 * ee. Hydrogen sulfide not produced; glucose acidified.


 * cc. Action in milk unknown or unreported.
 * d. Digests agar.


 * dd. Do not digest agar.
 * e. Deposit CaCO3 in sea-water gelatin and in agar media in old cultures. Do not grow in 12 to 30 per cent salt solutions.


 * ee. Does not deposit CaCO3 in sea-water gelatin or in agar media. Grows well in 12 to 30 per cent salt solutions.


 * bb. Non-motile. Cellulose attacked. Insoluble yellow pigment produced.


 * aa. Gelatin not liquefied.
 * b. Polar flagellate.
 * c. Does not attack cellulose. Produces an insoluble purple pigment in vegetable extracts.
