Yeasts mineral content

A mixture of corn flour, cottonseed flour, torula yeast, minerals, and vitamins developed by the Institute of Nutrition of Central America and Panama (INCAP) with the aid of funds from Central American governments, the Kellogg Foundation, the Rockefeller Foundation, and several other foundations. It has a protein content of about 25%. Incaparina can be used as a cereal for weanling infants and young children. It was test marketed in Nicaragua, El Salvador, Guatemala, and Colombia for the treatment and prevention of protein-energy malnutrition. 

Rumen Strain. In studies on strain Ml of M. ruminantium isolated from bovine rumen contents, we confirmed the results of Smith and Hungate (17), showing that this species requires factors present in rumen fiuid (23). It would not grow in medium containing H2-CO2, bicarbonate, sulfide, cysteine, yeast extract, trypticase, and minerals unless rumen fiuid was also added. In further experiments (23) we assayed fractions of rumen fiuid using the above medium and showed that growth factors could be separated into two components by acidification and ether extraction. One factor was not extractable with ether, and others were shown to be volatile acids. 

The term single cell protein (SCP) was coined at MIT by Professor C. L. Wilson in 1966 to represent the cells of algae, bacteria, yeast, and fungi grown for their protein contents. It should be noted that these microbial cells contain, in addition to proteins carbohydrates, lipids, nucleic acids, vitamins, and minerals.
