Torulopsis utilis

The biosynthesis of myo-inositol in a yeast (Torulopsis utilis) has been studied with formate-C14, acetate-2-Cu, formaldehyde-C14, and D-glucose (variously labeled).136 The small molecules are the best precursors for inositol, and, indeed, it appears that, when the cyclitol is formed from D-glucose, the sugar is fragmented before incorporation, instead of being cyclized directly.

Miyazaki et al. (1966, 1967 Miyazaki and Takemura 1966) have used column chromatography on DEAE-Sephadex A-25 to fractionate tRNA from Torulopsis utilis. They were able to purify an alanine, a valine and an isoleucine tRNA using 3 elution systems 1) Linear gradient of ammonium sulphate in 0.02 M potassium acetate, 1% dimethylformamide, pH 5.3 2) Linear gradient of KCl in 1 M potassium phosphate + 5% dimethylformamide, pH 6.1 or 6.2 at 30°C ... 

For point (ii) the predictions given above agree with the results of Henrici (H7) on growth of E. coli, and with those of Rabotnova and Mineeva (Rl) on growth of Torulopsis utilis and Pseudomonas fluorescens. The maximum concentration of organism attained becomes roughly independent of inoculum size and dependent on initial substrate concentration, as known since Henrici s experiments (H7).

A speculative scheme for the biosynthesis of lysine has been proposed by Strassman and Weinhouse on the basis of the distribution of the label in the lysine isolated from the yeast, Torulopsis utilis, grown on methyl-and carboxyl-labeled acetate. 

Torula yeast Torulopsis utilis) is a hardy type of yeast that can be propagated on a variety of substrates, such as press liquor obtained during the manufacture of dried citrus pulp, molasses, sulphite waste liquor from the paper industry, saccharified wood (both hexoses and pentoses can be used), and fruit wastes such as coffee beans, apples, etc. While brewers yeast is truly a by-product food, torula yeast is cultured specifically as a foodstuff for man and animals.
