based on differences in sugar utilization, and 

 produces the antibiotic cinerubin. 



53. Streptomyces cinnamomeus Benedict 

 et al, 1954 (Benedict, R. G., Dvonch, \\\, 

 Shot well, (). L., Pridham, T. G., and Lin- 

 denfelser, L. A. Antibiotics & Chemotherapy 

 2: 591, L952; 1: 1 1 10, L954). 



The corred name of this organism is S. 

 cinnamomeus l'. cinnamorru us. 



Morphology: Sporophores straight; later 

 descriptions indicate verticil formation. 

 Spores globose, 0.(3 n (Fig. 36). 



Sucrose nitrate agar: Growth colorless to 

 white to cream-colored. Aerial mycelium 

 white to ligh.1 cinnamon. 



Glucose-asparagine agar: Growth color- 

 less; light greenish-yellow to dull yellowish- 

 orange in reverse. Aerial mycelium white to 

 cinnamon. 



Nutrient agar: Growth cream-colored to 

 light lemon-yellow. No aerial mycelium. No 

 soluble pigment. 



Oatmeal agar: Growth tough, leathery, 

 yellowish-green to cream-yellow. Aerial my- 

 celium floccose, pale violet to faint cinna- 

 mon. Exudate tan to white. 



Starch agar: ( rrowth colorless to brownish.

Potato: Growth grayish-white to yellow- 

 green to light brown. Aerial mycelium light 

 gray to gray. No soluble pigment. 



( lelatin : ( irowth flocculent , dirty yellow to 

 white. Aerial mycelium cretaceous. No solu- 

 ble pigment. Rapid liquefaction. 



Milk: King light brown. Aerial mycelium 

 limited, white. Rapid peptonization. 



('arbon utilization: Utilizes xylose, fruc- 

 tose, inositol, starch, dextrin, galactose, and 

 maltose. Does not utilize arabinose, rham- 

 aose, < lubdt ol, and salicin. 



Nitrate reduction : Negative. 



Production of IbS: Negative. 



Temperature: Good growth al 25 :!7 C. 



Antagonistic properties: Produces cinna- 

 mycin, a polypeptide antibiotic.

Remarks: Pridham et al. (1956) described 

 a second form under the name of S. cinna- 

 momeus f. azacoluta; it produced a shell-pink 

 aerial mycelium on starch agar and an anti- 

 biotic, duramycin. 



Type culture: IMRU 3664.
