Source: Isolated from marine bottom de- posits. Habitat: Sea water. 18. Flavobacteriiim okeanokoites Zo- Bell and Upham, 1944. (Bull. Scripps Inst, of Oceanography, Univ. of Calif., 5, 1944, 270.) o.ke.a.no.ko.i'tes. Gr. mas.n. oceanus the ocean; Gr. fem.n. coite, coites bed; M.L. fem.gen.n. okeanokoites of the ocean bed. Rods, 0.8 to 0.9 b}^ 1.2 to 1.6 microns, with rounded ends, occurring singly and in long chains; many cells are coccoid. Motile by means of peritrichous fiagella. Gram-nega- tive. All media except the fresh-water broth, litmus milk and potato were prepared with sea water. Gelatin colonies: Small, circular, conve.x, entire, rust- or orange-colored; digest gela- tin. Gelatin stab: Slow, napiform liquefaction; j'ellow growth. Agar colonies: 2 mm in diameter, circular, entire, smooth, convex. Agar slant: Moderate, filiform, glistening, butyrous growth with yellow pigment. Sea-water broth: No pellicle; moderate turbidity; moderate, viscid sediment. Fresh-water broth: Good growth. Litmus milk: No visible change. Potato: No visible growth. Indole not produced. Hydrogen sulfide is produced. No acid or gas from glucose, lactose, maltose, sucrose, glycerol, mannitol, xylose or salicin. Starch not hydrolyzed. Casein is hydrolyzed. Non-lipolytic. Nitrites slowly produced from nitrates. Ammonia produced from peptone but not from urea. Aerobic, facultatively anaerobic. Optimum temperature, between 20° and 25° C. Source: Isolated from marine mud. Habitat: Sea water. 19. FJavobacterium marinovirosum ZoBell and Upham, 1944. (Bull. Scripps Inst, of Oceanograph}', Univ. of Calif., 5, 1944, 271.) ma. ri.no. vi.ro 'sum. L. adj. marinus of the sea; L. adj. virosus slimy; M.L. adj. marinovirosus probably intended to mean a marine slimy organism. Rods, 0.7 to 0.8 by 0.8 to 2.8 microns, with rounded ends, occurring singly and in long chains. Motile by means of peritrichous fiagella. Gram-negative. All media except the fresh-water broth, litmus milk and potato were prepared with sea water. Gelatin colonies: Small, circular, raised, rust-colored; gelatin slowly digested. Gelatin stab: Crateriform liquefaction becoming stratiform. Light orange pigment. Agar colonies: 1 to 2 mm, circular, convex, entire, smooth. Agar slant: Moderate, filiform, glistening, mucoid growth with grayish yellow pigment. Sea-water broth: Heavy turbidity; no pellicle; abundant, viscid sediment. Fresh-water broth: Good growth. Litmus milk: No visible change. Potato: No visible growth. Indole not produced. Hydrogen sulfide is produced. Does not ferment ghxerol, glucose, lac- tose, maltose, sucrose, mannitol, xylose or salicin. Starch not hydrolyzed. Casein not hydrolyzed. Non-lipolytic. Nitrites not produced from nitrates. Ammonia produced from peptone but not from urea. Aerobic, facultatively anaerobic. Optimum temperature, between 20° and 25° C. Source: Isolated from sea water and ma- rine mud. Habitat: Sea water. 20. Flavobaclerium suaveolens Soppe- land, 1924. (Jour. Agr. Res., 28, 1924, 275.) sua. ve'o. lens. L. adj. suaveolens having a sweet odor. Rods, 0.6 to 0.8 by 1.0 to 1.2 microns, with rounded ends, occurring singly and in pairs. Motile by means of peritrichous fiagella. Gram-negative on plain agar; Gram-posi- tive in young culture on milk powder agar.
