Abstract

Antinutritive Effects in Single-Cell Proteins (SCP): Studies on the Starvation and Refeeding In Rats. Rev. esp. FisioL, 30, 103-110. 1974.

The Chemical composition and biological quality of Saecharonvyces cercvisiae grown on molasses and dried afterwards, of Candida utilis grown on waste liquors from extraction of olive oil and of Candida lipolytica grown on puré n-paraffins

were investigated.
Amino-acid analysis showed a deficiency in sulphur aminoacids.- Growth and

proteins metabolism of male rats promoted by yeast’s proteins was compared with that promoted by caseín. The Biological Valúes obtained from single-cell proteins comes out much below that which could be expected from its contení in essential aminoacids.

The effect of starvation and refeeding on liver and on serum proteins was studied in rats receiving high and low protein diets. During refeeding, the rats fed yeast protein diets showed some significant differences in serum protein fractions and in liver proteins.
