 1923, 166; Corynebacterium fimi Jensen, Proc. Linnean Soc. New So. Wales, 59, 1934, 48.) fi'mi. L. noun jimus dung; L. gen. noun fimi of dung. Angular rods, 0.4 to 0.5 by 1.2 to 2.5 mi- crons, occasionally clubbed, curved or branched. Feebly motile by means of one or a few peritrichous flagella. Gram-vari- able. Gelatin agar: Gelatin hydrolyzed. Gelatin stab : Slow, infundibuliform lique- faction. Agar slant: Smooth, glistening, opaque, yellow growth. Broth: Uniformly turbid; scant, soft, cream-colored to yellow sediment. Filter paper in 0.5 per cent peptone broth: Paper strip reduced to a pulpy mass or weakened sufficiently so that the fibers separate on slight agitation. Potato: Cream-colored to yellow growth. Acid from glucose, fructose, arabinose, xylose, maltose, sucrose, lactose, raffinose, melezitose, dextrin, starch, salicin and glyc- erol; no acid from mannitol or dulcitol. Acetylmethylcarbinol not produced. Starch is hydrolyzed. Nitrites usually produced from nitrates. Ammonia production scant if at all. Aerobic, facultatively anaerobic. Optimum temperature, between 28° and 33° C. Source: Isolated from soil. Habitat: Soil. 6. Cellulomonas galba (Kellerman et al., 1913) Bergey et al., 1923. {Bacillus galhus Kellerman, McBeth, Scales and Smith, Cent. f. Bakt., II Abt., 39, 1913, 509; Bergey et al.. Manual, 1st ed., 1923, 157.) gal'ba. L. adj. galbus yellow. Cells 0.4 by 1.0 micron. Motile by means of one to three peritrichous flagella. Gram- positive. Gelatin stab: Liquefaction slow, usually appearing only after 10 days. Agar slant: Moderate, raised, canary- yellow growth. Cellulose agar: Narrow enzymatic zone around colonies. Broth: Turbid. Potato: Scant yellow growth. Acid from glucose, maltose, lactose, su- crose, starch and glycerol; no acid from mannitol. Nitrites not produced from nitrates. Aerobic, facultatively anaerobic. Optimum temperature, between 28° and 33° C. Source: Isolated from soil from Louisi- ana. Habitat: Soil. 7. Cellulomonas gelida (Kellerman et al., 1913) Bergey et al., 1923. (Bacillus geli- dus Kellerman, McBeth, Scales and Smith, Cent. f. Bakt., II Abt., 39, 1913, 510; Bergey et al.. Manual, 1st ed., 1923, 162.) ge'li.da. L. adj. gelidus cold. Small, angular rods, 0.4 to 0.6 by 0.8 to 2.0 microns, sometimes curved, clubbed or branched. Motile by means of one or a few peritrichous flagella. Gram-variable. Gelatin agar: Gelatin hydrolyzed. Gelatin stab: Liquefaction very slow if at all. Agar slant: Moderate, flat, grayish white growth. Broth: Uniformly turbid. Filter paper in 0.5 per cent peptone broth: Paper strip reduced to a pulpy mass or weakened sufficiently so that the fibers separate on slight agitation. Potato: Good growth. Acid from glucose, maltose, lactose, su- crose, starch and glycerol; no acid from mannitol. Acetylmethylcarbinol not produced. Starch is hydrolyzed. Nitrites not produced from nitrates. Ammonia occasionally produced. Aerobic, facultatively anaerobic. Optimum temperature, between 28° and 33° C. Source: Isolated from soil from Connecti- cut. Habitat: Soil. 8. Cellulomonas flavigena (Kellerman and McBeth, 1912) Bergey et al., 1923. (Ba- cillus flavigena (sic) Kellerman and McBeth, Cent. f. Bakt., II Abt., 34, 1912, 488; Bergey et al., Manual, 1st ed., 1923, 165.)
