162 STORRS AGRICULTURAL EXPERIMENT STATION. 
Fermentation tubes.—Dextrose bouillon is rendered acid, but there is no gas 
nor closed arm growth, nor is there acidity in any other sugar bouillon. In all 
cases the liquid is turned green. 
Bourlion.—A granular sediment and turbidity, but no pellicle. The bouillon 
is green after a few days. 
Milk.—No change in the reaction, but the milk is curdled and digested at 
both 20° and 37°, and becomes green in color, with a strong odor. 
Potato.—Scanty, filiform, flat, smooth, brownish-yellow. 
Grows at both 20° and 37°. Aerobic. 
B. lactis fluorescens II, n. s. A green fluorescent lophotrich. This is a 
common form. The culture from which the following description was made 
was isolated from Camembert cheese. Some variations are shown in the points 
. 
in brackets. 
Morphology.—A lophotrichic rod, sometimes forming chains. Individual 
elements, IM-I.4ux .6u-.9u. No spores nor capsules. Gram stain negative. 
Gelatine colony.—A very rapid liquefier, forming a cloudy pit. [A bead and a 
granular pit.]| On Aémus gelatine it is strongly alkaline. 
Gelatine stab.— Begins to liquefy in about three days, napiform. [ Infundibuli- 
form.] ‘The liquid shows fluorescent green, and there is a surface membrane, 
Agar streak.—Luxuriant, filiform or spreading, raised, smooth, of a white or 
brownish color, The agar turns green. The depth of the green color varies 
in different cultures. [Growth on agar in one culture is green, as well as the 
agar itself. | 
Fermentation tubes.—Dextrose bouillon is acid, but no other sugar bouillon, 
and there is no gas, nor closed arm growth. [Dextrose not acid. | 
Bouillon.—A sediment, a decided turbidity, and a flocculent pellicle. The 
liquid is green. 
Milk.—Is alkaline and curdled at 20° and subsequently digested, green. Has 
a pleasant odor. 
Potato.—Scanty, flat, smooth, brownish. [Luxuriant.] 
Grows at both 20° and 37°, but better at 20°. Aerobic, or facultative 
anaerobic. 
B. fluorescens minutissimus. A fluorescent lophotrich. This organism, 
described in 1899, is probably identical with the last. It shows slight variations 
and its description is reinserted here. 
Morphology.—An extremely small rod. Size, .5u-.74x'.5u. No chains, no 
spores, no capsules.’ Flagella were not made out. 
Gelatine colony.—A smooth, liquefying pit, without a nucleus, but granular. 
Gelatine stab,—Liquefies stratiform, with a cloudy liquid, which is not green. | 
Agar streak.—Luxuriant, soft white growth, with a green fluorescence. 
Bouilion.—A sediment and turbidity are formed, with a pellicle. In two days 
the bouillon is very cloudy, but not green.
