54 MEDICAL MYCOLOGY 



Many workers have reported excellent results with various fungi on car- 

 rot agar. The following formula of Falchi may be considered typical: 



Carrots 500 gm. 



Water 1000 c.c. 



Agar 20 gm. 



Peptone (Rostock) 10 gm. 



Among the formulae for synthetic media, those of Currie (1917) and 

 Fulmer & Grimes (1923) are widely used. 

 Currie : 



Ammonium nitrate 2.5 gm. 



Potassium dihydrogen phosphate 1.0 gm. 



Magnesium sulphate 0.25 gm. 



Carbohydrate 10.0 gm. 



Water 1000.0 c.c. 



Agar q.s. 



Fulmer & Grimes: 



Ammonium chloride 1.88 gm. 



Dipotassium hydrogen phosphate 1.0 gm. 



Calcium chloride 1.0 gm. 



Sucrose 50.0 gm. 



Agar 15.0 gm. 



Water 1000.0 c.c. 



Both formulae have been used in studies of yeasts and fermentation. 



Acton & McGuire (1931) report very good results with Actinomyces from 

 the medium described by Norris (1929). It consists of: 



Soluble starch 



Dipotassium hydrogen phosphate 



Calcium chloride 



Ferric chloride 



Sodium nitrate 



Asparagin 



Agar 



Water 



The medium is adjusted to pH 7.4.
