THE ACTINOMYCETES, Vol. II 



Starch: Hydrolysis positive. 



Cellulose: No decomposition. 



Nitrate reduction: Positive. 



Production of H 2 S: Positive. 



Carbon utilization: Utilizes glucose, 

 starch, dextrin, glycerol, galactose, maltose, 

 sucrose, trehalose, inositol, sorbitol, sodium 

 succinate, sodium citrate, and sodium ace- 

 tate. Does not utilize xylose, rafnnose, rham- 

 nose, lactose, arabinose, mannose, mannitol, 

 inulin, dulcitol, fructose, salicin, or esculin. 



Antagonistic properties: Produces an anti- 

 biotic, leucomycin. 



Remarks: S. kitasatoensis is similar to S. 

 reticuli in morphology of the mycelium, cul- 

 tural characteristics, and utilization of car- 

 bon sources, but different in several other 

 respects. 



131. Streptomyces kitasawacnsis Harada 

 and Tanaka, 1956 (Harada, Y. and Tanaka, 

 S. J. Antibiotics (Japan) 9A: 113-117, 1956). 



Morphology: Sporophores straight; no spi- 

 rals. 



Sucrose nitrate agar: Growth cream to 

 yellow. Aerial mycelium white with pale 

 pinkish tinge. 



Calcium malate agar: Growth cream-col- 

 ored. Aerial mycelium white. No soluble 

 pigment . 



Glucose-asparagine agar: Growth has 

 brownish tinge. Aerial mycelium white with 

 grayish tinge. Soluble pigment pale yellow- 

 ish-brown to pale greenish-yellow. 



Nutrient agar: Growth brownish. Aerial 

 mycelium absent or scarce. Soluble pigment 

 dark brown. 



Starch agar: Growth pale grayish-brown 

 to pale blackish-brown. Aerial mycelium 

 white. Soluble pigment pale greenish-yellow 

 to pale yellowish-brown. 



Gelatin: Growth white to gray. Aerial my- 

 celium absent or scarce. Soluble pigment 

 dark brown. No or weak liquefaction. 



Potato: Growth brown. Aerial mycelium 

 white. Soluble pigment dark brown. 



Milk: Growth in form of dark brownish 

 ring. Coagulation and peptonization. 



Carbon utilization: Utilizes i)(+)xylose, 

 D-mannitol, L-arabinose, salicin. Does not 

 utilize L(+)rhamnose, D-maltose. 



Antagonistic properties: Produces an anti- 

 tumor substance, carzinocidin. 



Habitat :Soil. 



132. Streptomyces lanatus Frommer, 1959 

 (Frommer, W. Arch. Mikrobiol. 32: 203, 

 1959). 



Morphology: Sporophores long, straight 

 or wavy, with short side branches; the ends 

 of these are more entangled than spiral- 

 shaped. 



Glycerol-sucrose agar: Growth abundant, 

 cottony, with red-brown reverse. Soluble 

 pigment brown to dark red-brown. 



Glucose-asparagine agar: Growth rose- 

 brown. Aerial mycelium velvety to cottony, 

 rose to gray-green. Soluble pigment brown- 

 ish. 



Calcium malate agar: Growth colorless to 

 yellowish. Aerial mycelium powdery, gray to 

 gray-green. No soluble pigment. 



Nutrient agar: Growth yellow-brown. Ae- 

 rial mycelium cream-colored or lacking. Sol- 

 uble pigment yellow-brown to dark brown. 



Starch: Weak hydrolysis. 



Potato: Growth yellow-brown. Aerial my- 

 celium powdery, white. Soluble pigment 

 black. 



Gelatin: Growth yellow. Aerial mycelium 

 yellow. Soluble pigment brown to red-brown. 

 Liquefaction medium. 



Milk: Growth abundant, dark brown. 

 Aerial mycelium powdery, cream-colored. 

 Coagulation, slow peptonization. 



Cellulose: No growth. 



Antagonistic properties: Produces actino- 

 mycin. 



Remarks: Closely related to S. purpureo- 

 chromogenes and S. phaeochromogenes.

 and Curtis, L916) Waksman and Henrici,
