SYNOPSIS The fatty acids lauric, myristic, and oleic, as well as long-chain bases (LCBs) obtained from sphingolipids, and Tween 80 “spare” the requirement for folate by Tetrahymena pyriformis W. Since LCBs are metabolized by the ciliate to ethano

A study of the enzymes of the orotate biosynthetic pathway in the kinetoplastid flagellate Crithidia fasciculata has revealed a number of differences between them and those of other organisms, either prokaryotic or eukaryotic. Carbamyl phosphate synt

Both adenosine and 2′-deoxyadenosine are inhibitory to the growth of Crithidia fasciculata . Half-maximal inhibition is caused by 0.3 mM adenosine. Effective reversal of the inhibition is brought about by uridine or cytidine; uracil has little effe

The growth characteristics of a number of species of ciliates have been reported recently in the literature. Most of these papers deal with saprozoic forms (Phelps, 1935, 1936, etc.) or with bacteria-feeders (Johnson, 1933; Kidder and Stuart, 1939b).

SUMMARY: In the use of an organism for assay of folic acid those compounds which affect the utilization of folic acid should be determined. With Tetrahymena pyriformis (geleii), it is shown that thymine (or thymidine), glycine, p-amino-benzoic acid,

SYNOPSIS. Crithidia fasciculata can synthesize threonine but it lacks an aspartokinase. The carbons of threonine may be derived from methionine when it is present in the medium. However, methionine can be synthesized by the organism provided organic

Inhibition of the growth of Tetrahymena pyriformis by 1-deaza-6-methyl-purine is not readily reversed by adenine. This purine analog also causes the death and eventual lysis of the cells. While it does not have a lethal effect, 6-methylpurine (6MeP)

1. In Eastman gelatin hydrolysate (EGH) and Factors I, II, and III from Liver Fraction L (heat- and alkali-treated to destroy thiamine) the ciliate Tetrahymena geleii W grows very poorly without added thiamine.2. A mixture of amino acids (11 AA) with
