CARBOHYDRATE METABOLISM 



The utilization of various carbohydrates by ciliates, trichomonad 

 flagellates, trypanosomes and related forms is well known. On the other 

 hand, the significance of sugars in the metabolism of phytoflagellates re- 

 mains problematical. Quantitative techniques have not demonstrated 

 utilization of glucose by Chilomonas Paramecium and Chlorogoniiim 

 euchlorum (327). Furthermore, sugars do not accelerate growth of Poly- 

 tomella agilis and Polytoma ocellata in peptone media (454), and sugars 

 apparently cannot replace acetate in the synthesis of reserve carbohy- 

 drates by phytoflagellates (344). In a few cases, stimulation of growth 

 has been reported in peptone media supplemented with certain sugars.
