 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.)
