 No growth in 6 per cent sodium chloride broth. Source: Five strains were isolated from soil. Habitat: Presumably soil.

Bact., 28, 1934, 217; Kiss, Lid and MoUand, Norske Viden- skaps-Akad., Oslo, 1 Mat.-Naturv. Klasse, No. 11, 1945, 9.) ter.res.tral.gi'ni.ca. L. noun terrestris land, earth; M.L. adj. alginicus pertaining to alginic acid from seaweed; M.L. adj. terrestralginicus land-alginic; presumably intended to mean an alginic bacterium from the soil. Long rods, 1.0 to 1.5 by 1.5 to 2.5 microns, with somewhat rounded ends, usually oc- curring singly but also in pairs, occasionally in chains of shorter rods. Motile. Granular. Gram-negative. Alginic acid plate: Colonies small, whitish in appearance with a slight metallic sheen. Alginic acid liquid medium: Medium at first clouded. Later a pellicle is formed on the surface of the medium; it is soon broken up due to active gas formation. Reaction of medium becomes slightly alkaline. Gelatin medium: Slow growth throughout stab, slow liquefaction at surface of medium at 18° C. Agar liquefaction: None. Glucose broth: Abundant turbidity; some sediment; no pellicle; slightly fluorescent. Litmus milk: Acid; milk coagulated; only limited digestion of coagulum. Potato: Abundant, pinkish, compact, dry growth on surface of plug, the rest of the plug becoming gray with a tendency to darkening. Starch plate: Limited growth along streak; no diastase. Aerobic to facultatively anaerobic. Optimum temperature, 30° C. Source: Isolated from New Jersey soil. Habitat: Soil.

3. Alginomonas alginovora (Waks- man et al., 1934) Kiss et al., 1945. {Bac- terium alginovorum Waksman, Carey and Allen, Jour. Bact., 28, 1934, 215; K&ss, Lid and Molland, Norske Videnskaps-Akad., Oslo, I Mat.-Naturv. Klasse, No. 11, 1945, 9.) al.gi.no'vo.ra. L. fem.n. alga seaweed; M.L. noun acidum alginicum alginic acid (derived from seaweed); L. v. voro to de- vour; M.L. adj. alginovorus alginic acid- destroying. Rods, 0.75 to 1.2 by 1.5 to 2.0 microns, with rounded to almost elliptical ends, especially when single, occurring frequently in pairs and even in chains. Encapsulated. Actively motile. Gram-negative. Alginic acid plate: Colony large, white in appearance, with coarse, granular center, entire margin. Clears up turbidity caused by alginic acid on the plate. No odor. Alginic acid liquid medium: Heavy pel- licle formation. Active production of an enzyme, alginase, which brings about the disappearance of alginic precipitate in sea- water medium. Salt-water medium: A slimy pellicle of a highly tenacious nature is produced, the whole medium later turning to a soft jelly. Sea-water gelatin : Active and rapid lique- faction in two to six days at 18° C; highly turbid throughout the liquefied zone. Agar liquefaction: Extensive softening of agar, no free liquid. Sea-water glucose broth: Abundant, uniform turbidity with surface pellicle; some strains give heavier turbidity, and others heavier pellicle. Litmus milk containing 3.5 per cent salt: No apparent growth. Potato moistened with sea water: Moist, spreading, ivory-colored growth; heavy sediment in free liquid at the bottom. Starch plate: Abundant, cream-colored, slimy growth; extensive diastase produc- tion. Aerobic to microaerophilic. Optimum temperature, 20° C. Source: Isolated from sea water, sea- bottom sediments and from the surface of algal growth in the sea. Habitat: Very common in the sea.
