DESCRIPTION OF SPECIES OF STREPTOMYCES 



229 



Cellulose: No1 attacked. 



Carbon utilization: Fructose and inositol 



well utilized; xylose, rhanim >se, sucrose, lac- 

 lose, raflinose, and mannitol not utilized; 

 galactose and trehalose slightly utilized.

\'2\. Streptomyces hirsutus Ettlinger et al., 

 L958 (Ettlinger, L., Corbaz, R., and Hiitter, 

 R. Arch. Mikrobiol. 31: 344, L958). 



Morphology: Sporophores long, mono- 

 podially branched; shorl open spirals with 

 about three coils are produced. Spores cov- 

 ered with narrow, long spines (PI. II, k). 



Glycerol nitrate agar: Growth colorless. 

 Aerial mycelium at first milky white, later 

 leek-green. 



Glucose-asparagine agar: Growth color- 

 less. No aerial mycelium. 



Glycerol malate agar: Growth at first 

 milky white; later covered with aerial my- 

 celium gradually colored leek-green. 



Starch-K\( );; agar: Growth milky white. 

 Aerial mycelium leek-green. Starch hydro- 

 lyzed. 



Gelatin: Growth whitish-yellow, covered 

 with 1 i t»; 1 1 1 green aerial mycelium. Slow lique- 

 faction. No soluble pigment. Melanin-nega- 

 tive. 



Potato: ( rrowth colorless. Aerial mycelium 

 at first white, later leek-green. 



.Milk: Pellicle heavy, lighl yellow. Aerial 

 mycelium white-gray. Rapid coagulation; no 

 peptonizat ion. 



Antagonistic properties: None. 



I labitat : Soil in Switzerland. 



Remarks: Some of the cultures described 

 by < rause et al. 1 1957), such as .1. acrimycini 

 and .1. acrimycini var. globosus, are closely 

 related to this organism. 



122. Streptomyces hominis (Bostroem 

 L890; emend. Waksman, 1919) Waksman 



and Ilenrici, L948. (Bostroem, E. Beitr. 

 pathol. Anat. allgem. Pathol. 9: 1-240, 

 1890; Waksman, S. A. Soil Sci. 8: 12!) 130, 

 I'M!). 



Synonyms: Streptothriz hominis Fouler- 

 ton, 1899. Oospora hominis Ridet, L911. 



Morphology: Sporophores straight. A few 

 dextrorse spirals on glycerol synthetic me- 

 dia. 



Sucrose nitrate agar: Growth white with 

 shade of yellow, turning brownish with age. 

 Aerial mycelium white with olive tinge. No 



soluble pigmenl . 



Glycerol malate agar: Growth yellowish. 

 Aerial mycelium with olive-green tinge. 



Nutrient agar: Growth yellowish. Aerial 

 mycelium white. No soluble pigment. 



Starch: Hydrolysis good. 



Potato: Growth yellowish to orange, be- 

 coming brown. Aerial mycelium white. Color 

 of plu»; unchanged, later becoming brown. 



Gelatin: Growth cream-colored. No aerial 

 mycelium. No soluble pigment. 



Milk: Rapid coagulation and peptoniza- 

 tion. 



Nitrate reduction: Positive. 



Sucrose: Xot inverted. 



Production of IPS: Negative. 



Habitat: Supposed to have been isolated 

 from abscess of palm of hand; probably an 

 air contamination. Appears to be related to 

 the S. griseus series.

 Shibata, 1956 (Belgian Patent 533,386. Ta- 

 keda Pharmaceutical Industries bid., .la- 

 pan. March 21, L956; Proc. Japan Acad. 

 32: (lis 653, 1956).

 Spores oval, 1 to 1 .."> by 1 .2 to 2 m- 



Sucrose nitrate agar: Growth colorless. 

 Aerial mycelium white. No soluble pigment. 



Nutrient agar: Growth colorless. No aer- 

 ial mycelium. No soluble pigment.
